The OpenFileDialog is used to select a file. These are the some common properties of OpenFileDialog class.

File name

The FileName Property is used to get or set file name selected in the file dialog box.

<Button Content="Openfile" Height="23" HorizontalAlignment="Left" Margin="52,198,0,0" Name="Button1" VerticalAlignment="Top" Width="167" />
