Most of the functionality for this class is found in the FileDialog class.

Windows Mobile 2003 for Pocket PC, Windows Mobile 2003 for Smartphone, Windows CE Platform Note: On the Pocket PC, if you do not specify a file name extension, the control appends the extension of the selected type from the dialog box. On Windows CE, the control does not append an extension. All platforms support the FilterIndex property, which returns the index of the selected extension filter.

The following code example illustrates creating a SaveFileDialog, setting members, calling the dialog box using the ShowDialog method, and saving the current file. The example requires a form with a button placed on it.

Private Sub button1_Click(sender As Object, e As System.EventArgs)
    Dim myStream As Stream
    Dim saveFileDialog1 As New SaveFileDialog()
    saveFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*"
    saveFileDialog1.FilterIndex = 2
    saveFileDialog1.RestoreDirectory = True
    If saveFileDialog1.ShowDialog() = DialogResult.OK Then
        myStream = saveFileDialog1.OpenFile()
        If (myStream IsNot Nothing) Then
            ' Code to write the stream goes here.
        End If
    End If
End Sub

protected void button1_Click(Object sender, System.EventArgs e)
    Stream myStream;
    SaveFileDialog saveFileDialog1 = new SaveFileDialog();
        "txt files (*.txt)|*.txt|All files (*.*)|*.*");
    if (saveFileDialog1.ShowDialog() == get_DialogResult().OK) {
        if ((myStream = saveFileDialog1.OpenFile()) != null) {

            // Code to write the stream goes here.
} //button1_Click
