Property Value

true if the dialog box restores the current directory to its original value if the user changed the directory while searching for files; otherwise, false. The default value is false.

The following code example uses the OpenFileDialog implementation of FileDialog and illustrates creating, setting of properties, and showing the dialog box. The example uses the RestoreDirectory property to ensure that the current directory is restored when the dialog box is closed. The example requires a form with a Button placed on it and the System.IO namespace added to it.

private void button1_Click(object sender, System.EventArgs e)
{
    Stream myStream = null;
    OpenFileDialog openFileDialog1 = new OpenFileDialog();
 
    openFileDialog1.InitialDirectory = "c:\\" ;
    openFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*" ;
    openFileDialog1.FilterIndex = 2 ;
    openFileDialog1.RestoreDirectory = true ;

    if(openFileDialog1.ShowDialog() == DialogResult.OK)
    {
        try
        {
            if ((myStream = openFileDialog1.OpenFile()) != null)
            {
                using (myStream)
                {
                    // Insert code to read the stream here.
                }
            }
        }
        catch (Exception ex)
        {
            MessageBox.Show("Error: Could not read file from disk. Original error: " + ex.Message);
        }
    }
}
    

protected void button1_Click(Object sender, System.EventArgs e)
{
    Stream myStream;
    OpenFileDialog openFileDialog1 = new OpenFileDialog();
    openFileDialog1.set_InitialDirectory("c:\\");
    openFileDialog1.set_Filter(
        "txt files (*.txt)|*.txt|All files (*.*)|*.*");
    openFileDialog1.set_FilterIndex(2);
    openFileDialog1.set_RestoreDirectory(true);
    if (openFileDialog1.ShowDialog().Equals(get_DialogResult().OK)) {
        if ((myStream = openFileDialog1.OpenFile()) != null) {
            // Insert code to read the stream here.
            myStream.Close();
        }
    }
} //button1_Click
