Ошибка времени выполнения unable to read beyond the end of the stream

I did some quick method to write a file from a stream but it’s not done yet. I receive this exception and I can’t find why:

Unable to read beyond the end of the stream

Is there anyone who could help me debug it?

public static bool WriteFileFromStream(Stream stream, string toFile)
{
    FileStream fileToSave = new FileStream(toFile, FileMode.Create);
    BinaryWriter binaryWriter = new BinaryWriter(fileToSave);

    using (BinaryReader binaryReader = new BinaryReader(stream))
    {
        int pos = 0;
        int length = (int)stream.Length;

        while (pos < length)
        {
            int readInteger = binaryReader.ReadInt32();

            binaryWriter.Write(readInteger);

            pos += sizeof(int);
        }
    }

    return true;
}

Thanks a lot!

Not really an answer to your question but this method could be so much simpler like this:

public static void WriteFileFromStream(Stream stream, string toFile) 
{
    // dont forget the using for releasing the file handle after the copy
    using (FileStream fileToSave = new FileStream(toFile, FileMode.Create))
    {
        stream.CopyTo(fileToSave);
    }
}

Note that i also removed the return value since its pretty much useless since in your code, there is only 1 return statement

Apart from that, you perform a Length check on the stream but many streams dont support checking Length.

As for your problem, you first check if the stream is at its end. If not, you read 4 bytes. Here is the problem. Lets say you have a input stream of 6 bytes. First you check if the stream is at its end. The answer is no since there are 6 bytes left. You read 4 bytes and check again. Ofcourse the answer is still no since there are 2 bytes left. Now you read another 4 bytes but that ofcourse fails since there are only 2 bytes. (readInt32 reads the next 4 bytes).

I presume that the input stream have ints only (Int32). You need to test the PeekChar() method,

while (binaryReader.PeekChar() != -1)
{
  int readInteger = binaryReader.ReadInt32();
  binaryWriter.Write(readInteger);          
}

You are doing while (pos < length) and length is the actual length of the stream in bytes. So you are effectively counting the bytes in the stream and then trying to read that many number of ints (which is incorrect). You could take length to be stream.Length / 4 since an Int32 is 4 bytes.

After reading the stream by the binary reader the position of the stream is at the end, you have to set the position to zero «stream.position=0;»

  • I do not think you have to use a while loop, but you must write and read the exact kind of data in correct order.

    For writing try this:

    writer.Write(txtName.Text);
writer.Write(txtNickName.Text);
writer.Write(rdoMale.Checked);
writer.Write(txtAge.Text);
writer.Write(dtpBirthDate.Value.ToBinary());
writer.Write(txtEmail.Text);
writer.Write(txtPhone.Text);
writer.Write(cbxStatus.SelectedItem.ToString());

    For reading, remove the while line (or replace with if, which checks that the file is not empty) and try this:

    txtName.Text = reader.ReadString();
txtNickName.Text = reader.ReadString();
rdoMale.Checked = reader.ReadBoolean();
txtAge.Text = reader.ReadString();
dtpBirthDate.Value = DateTime.FromBinary(reader.ReadInt64());
txtEmail.Text = reader.ReadString();
txtPhone.Text = reader.ReadString();
cbxStatus.SelectedItem = reader.ReadString();

    (If cbxStatus does not contain strings, then it has to be saved in different manner. Show some details about
    cbxStatus items if the last line does not work).

thats a permission issue. you didnt follow the install instructions correctly.

**How to Install:**

**+** Stop your Torrent from seeding (close it, maybe check your task manager)

**+** Move the Warhammer Online — Return of Reckoning outside the ReturnofReckoning-March2020 folder and move it to c: … for instance move it to c:Games
(but **NOT** inside c: Program Files or c: Program Files (x86); it should be in a folder which it have write access)

**+** Remove the write-protection from all the files in the Warhammer Online — Return of Reckoning folder.
(right click on the War Online — RoR folder > properties > disable the read-only box)

**+** Check that your whole Warhammer Online — Return of Reckoning folder is whitelisted in your Antivirus program and check if your Firewall or Maleware doesn’t interfere with the install.

**+** You may also try running the launcher with Administrator privileges.
(Right click on the RoRLauncher.exe > properties > run administrator)

**+** Run the RoRLauncher.exe
**+** Let it update (sometimes it needs a few seconds until it starts)
**+** Exit launcher and rerun it again
**+** Repeat the last 2-steps until there is no update left
**+** Launch the game

**!!!** [If you don’t have DirectX 9.0c, installed it is required, and now this is also included in the torrent. In the ReturnOfReckoning-March2020 folder find the dx90c folder, open that and run DXSETUP.exe]

What Valve game does this happen in

Dota 2

Reference file in a Source 2 game

D:SteamSteamAppscommondota 2 betagamedotapak01_dir.vpkmodelsheroeshoodwinkhoodwink.vmdl_c

Expected behavior

I expect when I double click the left mouse button a hoodwink.vmdl_c file, no error should appear and the MODEL subtab should display the loaded model that I can export.

What version of VRF are you using? On what platform?

  • I do not think you have to use a while loop, but you must write and read the exact kind of data in correct order.

    For writing try this:

    writer.Write(txtName.Text);
writer.Write(txtNickName.Text);
writer.Write(rdoMale.Checked);
writer.Write(txtAge.Text);
writer.Write(dtpBirthDate.Value.ToBinary());
writer.Write(txtEmail.Text);
writer.Write(txtPhone.Text);
writer.Write(cbxStatus.SelectedItem.ToString());

    For reading, remove the while line (or replace with if, which checks that the file is not empty) and try this:

    txtName.Text = reader.ReadString();
txtNickName.Text = reader.ReadString();
rdoMale.Checked = reader.ReadBoolean();
txtAge.Text = reader.ReadString();
dtpBirthDate.Value = DateTime.FromBinary(reader.ReadInt64());
txtEmail.Text = reader.ReadString();
txtPhone.Text = reader.ReadString();
cbxStatus.SelectedItem = reader.ReadString();

    (If cbxStatus does not contain strings, then it has to be saved in different manner. Show some details about
    cbxStatus items if the last line does not work).

одна из причин сбоя кода — если файл содержит дополнительные байты (т. е. файл длиной 7 байт). Ваш код будет срабатывать на последних 3 байтах.

чтобы исправить-рассмотрим вычисление числа целых чисел заранее и с помощью for читать:

var count = br.BaseStream.Length / sizeof(int);
for (var i = 0; i < count; i++)
{
  int v = br.ReadInt32();
  textBox1.Text = v.ToString();
}

обратите внимание, что этот код будет просто игнорировать последние 1-3 байта, если они там есть.

вы должны использовать более надежный способ выяснить, когда вы находитесь в конце потока, а не катить свой собственный счетчик с sizeof(int). Ваш метод может быть недостаточно точной, и тот факт, что вы используете небезопасный код, что тоже не слишком хорошо.

один из способов зонда, если вы находитесь в конце потока или нет, чтобы использовать PeekChar способ:

while (br.PeekChar() != -1)
{
    // 3.
    // Read integer.
    int v = br.ReadInt32();
    textBox1.Text = v.ToString();
}

более распространенным решением является запись числа ints, которые вы сохраняете в двоичном файле перед фактическим списком целых чисел. Таким образом, вы знаете, когда остановиться, не полагаясь на длину или положение потока.

One thing that looks different is line 46:
d.Age = (int)r.ReadInt64();

You are reading a 64 bit integer but you have created it on line 35 as a 32 bit integer (int).

Change to
d.Age = (int)r.ReadInt32();

hmm… Did you save the data into a file in the same order then you are retreiving them back out?

the point is that you cannot just simply asign some binary data to something. You have to get the data into the text in some order, and then retreive …

Thanks single blade , it works now. but why wont the number show up clearly in the text?

why am i being shown some weird square after the file is produced??

btw, why do you use a BinaryRader class, becuase you only read from a text file?
Why you dont use StreamReader instead, and you wont even need to convert byte into string, something?

An idea.

i know the method of StreamReader. i wanted to investigate how to do it with Binary,
why does it refuse to translate it to an int..?

the point is that you cannot just simply asign some binary data to something. You have to get the data into the text in some order, and then retreive them back in the same way:EXAMPLE!

If this is not enough its better to take a look into some other example, that you will learn how to use bytes and converted them back to the characters (strings, integers,…).

Give it some time and go through all the code slowely:

The square usually means some non visual output like a new line character or tab or something similar.

Check your file and make sure there is nothing in it but the age.

    }
    public void Save(BinaryWriter bw)

        bw.Write(Name);
        bw.Write(Age);
        bw.Write(Height);
    //    if(Yadid!=null)
    //        Yadid.Save(bw);
    }
    public static Person Load(BinaryReader br)
    {
        Person person = new Person();
        person.Name = br.ReadString();
        person.Age = br.ReadInt32();
        person.Height = br.ReadDouble();
       // person.Yadid = Person.Load(br);
        return person;
    }

}

Thats the teachers code. it works.
i just applied different variables and added a class. Why doesnt my code work? it follows the same principles, or does it not?

  • I do not think you have to use a while loop, but you must write and read the exact kind of data in correct order.

    For writing try this:

    writer.Write(txtName.Text);
writer.Write(txtNickName.Text);
writer.Write(rdoMale.Checked);
writer.Write(txtAge.Text);
writer.Write(dtpBirthDate.Value.ToBinary());
writer.Write(txtEmail.Text);
writer.Write(txtPhone.Text);
writer.Write(cbxStatus.SelectedItem.ToString());

    For reading, remove the while line (or replace with if, which checks that the file is not empty) and try this:

    txtName.Text = reader.ReadString();
txtNickName.Text = reader.ReadString();
rdoMale.Checked = reader.ReadBoolean();
txtAge.Text = reader.ReadString();
dtpBirthDate.Value = DateTime.FromBinary(reader.ReadInt64());
txtEmail.Text = reader.ReadString();
txtPhone.Text = reader.ReadString();
cbxStatus.SelectedItem = reader.ReadString();

    (If cbxStatus does not contain strings, then it has to be saved in different manner. Show some details about
    cbxStatus items if the last line does not work).
