in wpf, how can I use a standard dialog to select a directory

Question

I need the user to select a directory, not a file. How can I use Microsoft.Win32.OpenFileDialog (or any other component) to do that?

I'm using WPF4.0 in VisualStudio 2010 (.net 4.0)

Answer 1

use the System.Windows.Forms.FolderBrowserDialog :

var dlg = new System.Windows.Forms.FolderBrowserDialog();
dlg.ShowNewFolderButton = true; //if you want new folders as well
dlg.SelectedPath = someStartPath; //where to start
if( dlg.ShowDialog() == DialogResult.OK )
{
  //ok user selected something
  DoStuffWith( dlg.SelectedPath );
}

您可以通过Windows API代码包来访问Win32生态系统中的该对话框以及许多其他标准对话框和控件。
