Determining if file exists using c# and resolving UNC path

by

You can create a FileInfo for an non-existing file. But then you can check the FileInfo.Exists property to determine whether the file exists, e.g:

FileInfo fi = new FileInfo(somePath);
bool exists = fi.Exists;

Update:
In a short test this also worked for UNC paths, e.g. like this:

FileInfo fi = new FileInfo(@"\\server\share\file.txt");
bool exists = fi.Exists;

Are you sure that the account (under which your application is running) has access to the share. I think that (by default) administrative rights are required to access the share “c$”.
