Hi,

I'm using C# in a WPF application and need to display a windows dialog to let the user specify a folder to use.

This code works in displaying the folder, but I get an error when testing the return result of the dialog:

            FolderBrowserDialog fdlg = new FolderBrowserDialog();
            //fdlg.ShowNewFolderButton = false;
            fdlg.Description = "Select Folder to save the Zip file";
            fdlg.RootFolder = System.Environment.SpecialFolder.MyDocuments;
            //fdlg.RootFolder = Environment.SpecialFolder.Desktop;             fdlg.ShowDialog();
            DialogResult result = fdlg.ShowDialog();

            if (result == DialogResult.OK)

The error occurs on the OK in the final line above (everything else is fine) and is:

'System.Nullable<bool>' does not contain a definition for 'OK' and no extension method 'OK' accepting a first argument of type 'System.Nullable<bool>' could be found (are you missing a using directive or an assembly reference?)

any ideas what I'm missing or an alternative technique?
