How do I use a FolderBrowserDialog with Environment.SpecialFolder?

I currently am writing a lightweight and flexible program to view and possibly edit pictures. Everything is going smoothly, but I've run into a roadblock. The RootFolder property of a FolderBrowserDialog control is of the Environment.SpecialFolder type, which is an enum. Due to this nature, I can't set its value as a string. How can I use the SelectedPath property of the FolderBrowserDialog to set the RootPath property for a FolderBrowserDialog?

(Note: The FolderBrowserDialog is for selecting the default folder for opening images from)

In addition to the below solutions if you are wanting to restore your folder browser dialog to the last selected path when it reopens just save the value of SelectedPath when the OK button of folderBrowserDialog is clicked and then right before you call ShowDialog() again just reassign the value. i.e.

something like this

if (lastPath != "")
{
folderBrowserDialog1.SelectedPath = lastPath;
}
if (folderBrowserDialog1.ShowDialog() == DialogResult.OK)
{
lastPath = folderBrowserDialog1.SelectedPath;
}

** lastPath being a string you have defined somewhere.

Hi,

I think you need to take a look at: Environment.GetFolderPath(Environment.SpecialFolder).
If you feed the result of this call to the FolderBrowserDialog you should be OK.

Try using Environment.SpecialFolder.MyComputer, set the SelectedPath, and then call ShowDialog(). I did the following and it worked fine:

C#

FolderBrowserDialog dlg = new FolderBrowserDialog();
dlg.RootFolder = Environment.SpecialFolder.MyComputer;
dlg.SelectedPath = @"d:\dev";
dlg.ShowDialog();
