hi i have the following code to perform xml serialization:

private void SaveButton_Click(object sender, RoutedEventArgs e)
        {
            string savepath;
            SaveFileDialog DialogSave = new SaveFileDialog();
            // Default file extension
            DialogSave.DefaultExt = "txt";
            // Available file extensions
            DialogSave.Filter = "XML file (*.xml)|*.xml|All files (*.*)|*.*";
            // Adds a extension if the user does not
            DialogSave.AddExtension = true;
            // Restores the selected directory, next time
            DialogSave.RestoreDirectory = true;
            // Dialog title
            DialogSave.Title = "Where do you want to save the file?";
            // Startup directory
            DialogSave.InitialDirectory = @"C:/";
            DialogSave.ShowDialog();
            savepath = DialogSave.FileName;
            DialogSave.Dispose();
            DialogSave = null;

            FormSaving abc = new FormSaving();
            if (MajorversionresultLabel != null && MajorversionresultLabel.Content != null && MajorversionLabel.Content.ToString() != string.Empty)
            abc.Majorversion = MajorversionresultLabel.Content.ToString();
            //abc.Minorversion = MinorversionresultLabel.Content.ToString();
            //abc.Projectnumber = ProjectnumberresultLabel.Content.ToString();
            //abc.Buildnumber = BuildnumberresultLabel.Content.ToString();
            //abc.Previousbuildversion = PreviousbuildversionresultLabel.Content.ToString();
            abc.Startzbuildfrom = StartzbuildfromcomboBox.SelectedItem;

            using (Stream savestream = new FileStream(savepath, FileMode.Create))
            {

                    XmlSerializer serializer = new XmlSerializer(typeof(FormSaving));
                    serializer.Serialize(savestream, abc);
            }



        }

the error «There was an error generating the XML document» occurs at serializer.Serialize(savestream, abc);

my form saving class:

public class FormSaving
        {

            public string Majorversion
            {
                get;

                set;

            }
            public string Minorversion
            {
                get;

                set;

            }
            public string Projectnumber
            {
                get;

                set;

            }
            public string Buildnumber
            {
                get;

                set;

            }
            public string Previousbuildversion

                get;

                set;

            }
            public object Startzbuildfrom
            {
                get;

                set;
            }
    }

can anyone help me fix this?

EDIT:

i tried this but it doesnt work as well:

under «save button»

abc.Startzbuildfrom = StartzbuildfromcomboBox.SelectedItem.ToString();

under «load button»

StartzbuildfromcomboBox.SelectedItem = abc.Startzbuildfrom;

here is how i populate my combobox items:

<ComboBox Height="23" Margin="577,72,497,0" Name="StartzbuildfromcomboBox" VerticalAlignment="Top"><ComboBoxItem>library</ComboBoxItem></ComboBox>

привет, у меня есть следующий код для сериализации xml:

private void SaveButton_Click(object sender, RoutedEventArgs e)
        {
            string savepath;
            SaveFileDialog DialogSave = new SaveFileDialog();
            // Default file extension
            DialogSave.DefaultExt = "txt";
            // Available file extensions
            DialogSave.Filter = "XML file (*.xml)|*.xml|All files (*.*)|*.*";
            // Adds a extension if the user does not
            DialogSave.AddExtension = true;
            // Restores the selected directory, next time
            DialogSave.RestoreDirectory = true;
            // Dialog title
            DialogSave.Title = "Where do you want to save the file?";
            // Startup directory
            DialogSave.InitialDirectory = @"C:/";
            DialogSave.ShowDialog();
            savepath = DialogSave.FileName;
            DialogSave.Dispose();
            DialogSave = null;

            FormSaving abc = new FormSaving();
            if (MajorversionresultLabel != null && MajorversionresultLabel.Content != null && MajorversionLabel.Content.ToString() != string.Empty)
            abc.Majorversion = MajorversionresultLabel.Content.ToString();
            //abc.Minorversion = MinorversionresultLabel.Content.ToString();
            //abc.Projectnumber = ProjectnumberresultLabel.Content.ToString();
            //abc.Buildnumber = BuildnumberresultLabel.Content.ToString();
            //abc.Previousbuildversion = PreviousbuildversionresultLabel.Content.ToString();
            abc.Startzbuildfrom = StartzbuildfromcomboBox.SelectedItem;

            using (Stream savestream = new FileStream(savepath, FileMode.Create))
            {

                    XmlSerializer serializer = new XmlSerializer(typeof(FormSaving));
                    serializer.Serialize(savestream, abc);
            }



        }

ошибка «Произошла ошибка при создании XML-документа» возникает в serializer.Serialize(savestream, abc);

мой класс сохранения формы:

public class FormSaving
        {

            public string Majorversion
            {
                get;

                set;

            }
            public string Minorversion
            {
                get;

                set;

            }
            public string Projectnumber
            {
                get;

                set;

            }
            public string Buildnumber
            {
                get;

                set;

            }
            public string Previousbuildversion
            {
                get;

                set;

            }
            public object Startzbuildfrom
            {
                get;

                set;
            }
    }

кто-нибудь может помочь мне это исправить?

EDIT:

Я пробовал это, но это тоже не работает:

под «кнопкой сохранения»

abc.Startzbuildfrom = StartzbuildfromcomboBox.SelectedItem.ToString();

под «кнопкой загрузки»

StartzbuildfromcomboBox.SelectedItem = abc.Startzbuildfrom;

вот как я заполняю элементы поля со списком:

<ComboBox Height="23" Margin="577,72,497,0" Name="StartzbuildfromcomboBox" VerticalAlignment="Top"><ComboBoxItem>library</ComboBoxItem></ComboBox>
