copied!<p>The easiest way is to just do it (i.e. try to read a file, for example). As Jared mentioned, there is no way to make sure that you will be able to read in the future (network failure, change of permissions, etc).</p> <p>As far as code goes, you could use the <a href="http://msdn.microsoft.com/en-us/library/system.io.directoryinfo.aspx" rel="nofollow noreferrer">DirectoryInfo</a> class for some attempts at an answer:</p> <pre><code> string remotePath = @"\\server\share$"; bool haveAccess = false; DirectoryInfo di = new DirectoryInfo(remotePath); if (di.Exists) { try { // you could also call GetDirectories or GetFiles // to test them individually // this will throw an exception if you don't have // rights to the directory, though var acl = di.GetAccessControl(); haveAccess = true; } catch (UnauthorizedAccessException uae) { if (uae.Message.Contains("read-only")) { // seems like it is just read-only haveAccess = true; } // no access, sorry // do something else... } } </code></pre> <p>There are many shortcomings in the above code (such as the hard-coded "read-only" test), but it is just an example used to illustrate what you could do. DirectoryInfo has a few other helper methods that you can use to list the files in the folder. If you don't have access, the methods will throw an <code>UnauthorizedAccessException</code> exception which you can use to test why the access failed. Check out the info on <a href="http://msdn.microsoft.com/en-us/library/t1h6d4k4.aspx" rel="nofollow noreferrer">GetAccessControl</a> for further details on the exceptions it throws.</p>
