NetworkShareAccesser: 远程PC1 文件 copy 到PC2 文件夹

Usage:

string strRepoBundlePath = @"\\at1-repo01\ATE\Bundles\SharePoint\Open\denyopen.zip";
string strRemoteBundle = @"\\"+serverHostName+@"\c$\denyopen.zip";using (NetworkShareAccesser.Access(serverHostName, domain, userName, password))
{
       File.Copy(@strRepoBundlePath, @strRemoteBundle);
}

WARNING: Please make absolutely sure, that Dispose of the NetworkShareAccesser is called (even if you app crashes!), otherwise an open connection will remain on Windows. You can see all open connections by opening the cmd prompt and enter net use.
