DirectoryInfo, FileInfo and very long path

Question

I try to work with DirectoryInfo, FileInfo with very long path.

• I try use \\?\c:\long path (i got illegal caracter with fileInfo and DirectoryInfo)
• I try use file://c:/long path (i got uri not supported)

Can i use ~ in a path or something else.

I read this post but i would like to use another way that call a API. Is it any other solutions ?

There is an article from microsoft for use \\? in file path link text

The question is how can i work with very long path, and DirectoryInfo, and FileInfo for path who are more longer that 256 char

Answer 1

Looking at the Long Paths in .NET blog post series, it looks like going to the Win32 API through P/Invoke is the only solution at the moment, other than restructuring your directories so that you don't hit the limit.

A way I solved this issue in the past was using the library from Delimon called Delimon.Win32.IO. It looks like his site http://www.delimon.be is down at the moment. But I had used it on a project in the past and it worked like a champ. I can try to track it down for you later this evening or just try to find a valid link to it somewhere via google. Cheers. Here's another link talking discussing this issue.

Hi ElvisLives,

is it possible to get the "Delimon.Win32.IO.dll" from you, and how. www.delimon.be seems permanent down.
