Question about UNC shares

Question

Hello I have a fileserver 10.10.2.19/Homes. I want the C# code I am running in an ASP.NET page to be able to browse this directory using the System.IO namespace. However the share above has a very specific login for access. This is for security reasons. How do I pass the username/password to it in order to be able to browse this directory??? Thanks DanWifi

Awesome this works well but I have another question. How do I use this connection to actually pull files from that share? I looked up the WNet functions on the MSDN site but it only seems to have ways to create a mapped drive to the connection. This wont work for me since at any given time there could be more than 26 users connected to this page at a time. Thanks for you help! Dan

PInvoke using WNETADDConnection2 win32 API function. It will establish a connection (without a mapped drive) using the login you provide. You must be sure to specify the correct provider. If this doesn't work you'll have to write code to try every available provider. I've written an article on how to do this (it's in Delphi). http://www.delphi3000.com/articles/article_3823.asp using System.Runtime.InteropServices; ... ... //Win32 unmanaged functions private struct NETRESOURCE { public UInt32 dwScope; public UInt32 dwType; public UInt32 dwDisplayType; public UInt32 dwUsage; public string lpLocalName; public string lpRemoteName; public string lpComment; public string lpProvider; public void Initialize() { dwScope = 0; dwType = 0; dwDisplayType = 0; dwUsage = 0; lpLocalName = null; lpRemoteName = null; lpComment = null; lpProvider = null; } }; [DllImport(mpr.dll)] private static extern UInt32 WNetAddConnection2( NETRESOURCE nr string password string username UInt32 dwFlags ); ... ... private void button1_Click(object sender System.EventArgs e) { NETRESOURCE nr = new NETRESOURCE(); nr.Initialize(); nr.lpProvider = Micrsoft Network Provider; nr.lpRemoteName = @\servername\sharename; WNetAddConnection2(nr username password 0); }
