Very elegant solution inspired from <a href="http://social.msdn.microsoft.com/Forums/vstudio/en-US/287ca606-86da-4794-baed-2ad5db9bc833/access-to-remote-folder" rel="noreferrer">this one</a>. This one uses only .Net library and does not need to use any command line or Win32 API.

Code for ready reference:

<pre><code>NetworkCredential theNetworkCredential = new NetworkCredential(@"domain\username", "password");
CredentialCache theNetCache = new CredentialCache();
theNetCache.Add(new Uri(@"\\computer"), "Basic", theNetworkCredential);
string[] theFolders = Directory.GetDirectories(@"\\computer\share");

Use this code for Impersonation its tested in MVC.NET maybe for dot net core it required some change, If you want to dot net core let me know I will share.
<pre><code> public static class ImpersonationAuthenticationNew

 private static extern bool LogonUser(string usernamee, string domain, string password, LogonType dwLogonType, LogonProvider dwLogonProvider, ref IntPtr phToken);
 [DllImport(&quot;kernel32.dll&quot;)]
 private static extern bool CloseHandle(IntPtr hObject);
 public static bool Login(string domain,string username, string password)
 { 
 IntPtr token = IntPtr.Zero;
 var IsSuccess = LogonUser(username, domain, password, LogonType.LOGON32_LOGON_NEW_CREDENTIALS, LogonProvider.LOGON32_PROVIDER_WINNT50, ref token);
 if (IsSuccess)

string[] theFolders = Directory.GetDirectories(@"\\computer\share");
