save file dialog help

Question

Greetings Friends,

I have a problem while saving a batch file.
In my program i have a button, when button clicks it need to save the file with extension .bat. I defined it as " SaveFileDialog saveFileDialog1 = new SaveFileDialog();

            saveFileDialog1.InitialDirectory = @"C:\";

            saveFileDialog1.Title = "";

            saveFileDialog1.CheckFileExists = true;

            saveFileDialog1.CheckPathExists = true;

            saveFileDialog1.DefaultExt = "bat";

            saveFileDialog1.Filter = "Batch Files (*.bat)|*.bat"|All files (*.*)|*.*;

            saveFileDialog1.FilterIndex = 2;

            saveFileDialog1.RestoreDirectory = true;

            if (saveFileDialog1.ShowDialog() == DialogResult.OK)

            {

              textBox1.Text = saveFileDialog1.FileName;

            } "
The dialog box appears but the file is not saving.
please help me.
