Translate drive letter to UNC for mapped drives

[Michael Russell]

Hi, I'm converting a C++ program over to C# (on .Net 2.0), and am not
sure of the best way to look up the UNC path for mapped drives.

The way the C++ program does this is it iterates through a listing of
drive letters, then calls WNetGetUniversalName for each to get the UNC.
.Net 2.0 seems to have a fairly broad selection of IO handling
options, but I've not yet found one to handle my problem.

Any pointers?

Michael,

.NET doesn't have anything to handle this out of the box. However, you
can call the WNetGetUniversalName API through the P/Invoke layer if you
wish.

Hope this helps.

Like Nicholas said, you should use WNetGetUniversalName. Here's a code
snippet that shows how to use P/Invoke to get the UNC path:

Thanks John and Nicholas. A little disappointing that there isn't
something built-in, but I appreciate the confirmation and the link to
the code snippet.
