Answer 1

执行此操作的最佳方法是p/invoke WNetUseConnection.

[StructLayout(LayoutKind.Sequential)] 
private class NETRESOURCE
{ 
        public int dwScope = 0;
        public int dwType = 0;
        public int dwDisplayType = 0;
        public int dwUsage = 0;
        public string lpLocalName = "";
        public string lpRemoteName = "";
        public string lpComment = "";
        public string lpProvider = "";
}


[DllImport("Mpr.dll")] 
private static extern int WNetUseConnection(
            IntPtr hwndOwner,
            NETRESOURCE lpNetResource,
            string lpPassword,
            string lpUserID,
            int dwFlags,
            string lpAccessName,
            string lpBufferSize,
            string lpResult
        );

这里的示例代码.

来自http://social.msdn.microsoft.com/Forums/vstudio/en-US/287ca606-86da-4794-baed-2ad5db9bc833/access-to-remote-folder的非常优雅的解决方案.这个只使用.Net库,不需要使用任何命令行或Win32 API.

准备参考的代码:

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

Answer 3

您可以使用WindowsIdentity类(使用登录标记)在读取和写入文件时进行模拟.

var windowsIdentity = new WindowsIdentity(logonToken);
using (var impersonationContext = windowsIdentity.Impersonate()) {
    // Connect, read, write
}

Answer 4

您可以使用 system.diagnostocs.process 调用“net use .... with userid and password”或调用这些命令的命令 shell。
