File Save problem

Question

Hi...

 

I am trying to save a file in the MDI -  which uses the RichTextBox...    But I am not able to save the formatting to the text..

 

Example : -   If I chnage the font, color, size of the text.. it doesnt save the formatting but stores the simple text..

NOTE:  this is happening when I select the RTF option in the Save File Dialog box

 

public void save_file()

{

savedlg.Filter = "Text Documents (*.txt)|*.txt|Rich Text Documents (*.rtf)|*.rtf";

DialogResult res = savedlg.ShowDialog();

RichTextBox t1 = (RichTextBox)tabControl1.SelectedTab.Controls[0];

if (res == DialogResult.OK)

{

FileStream f1 = new FileStream(savedlg.FileName, FileMode.Create, FileAccess.Write);

StreamWriter sw = new StreamWriter(f1);

char[] ary = t1.Text.ToCharArray();

int i = 0;

while (i <= ary.Length - 1)

{

sw.Write(ary[i++]);

}

sw.Close();

f1.Close();

fileName = savedlg.FileName;

tabControl1.SelectedTab.Text = System.IO.Path.GetFileName(fileName);

fileName = "";

}

else if (res == DialogResult.Cancel)

return;

else

{

t1.SaveFile(fileName, RichTextBoxStreamType.RichText);

tabControl1.SelectedTab.Text = System.IO.Path.GetFileName(fileName);

}

}

 

 

 

Please Help me...!!!
