要映射一个网络目录为本地驱动器，需要调用系统DLL的WNetAddConnection2函数来进行添加。

首先，系统函数的申明如下：

using System.Runtime.InteropServices;

[DllImport("mpr.dll", EntryPoint="WNetAddConnection2")]

public static extern uint WNetAddConnection2(

[In] NETRESOURCE lpNetResource,

string lpPassword,

string lpUsername,

uint dwFlags);

[DllImport("Mpr.dll")]

public static extern uint WNetCancelConnection2(

string lpName,

uint dwFlags,

bool fForce);

[StructLayout(LayoutKind.Sequential)]

public class NETRESOURCE

{

public int dwScope;

public int dwType;

public int dwDisplayType;

public int dwUsage;

public string LocalName;

public string RemoteName;

public string Comment;

public string Provider;

}

添加映射网络驱动器调用的代码如下：

NETRESOURCE myNetResource = new NETRESOURCE();

myNetResource.dwScope = 2; //2:RESOURCE_GLOBALNET

myNetResource.dwType = 1 ; //1:RESOURCETYPE_ANY

myNetResource.dwDisplayType = 3; //3:RESOURCEDISPLAYTYPE_GENERIC

myNetResource.dwUsage = 1; //1: RESOURCEUSAGE_CONNECTABLE

myNetResource.LocalName = "T:";

myNetResource.RemoteName = yourNetworkPath;

myNetResource.Provider = null;

uint nret = WNetAddConnection2( myNetResource, pwd, username, 0);

注意：如果正确，返回值是0；否则错误。

删除映射网络驱动器调用的代码如下：

uint nret = WNetCancelConnection2( yourNetDriveName, 1,true);

//局域网内copy文件

        private void button1_Click(object sender, EventArgs e)
        {
            if (Ping(remoteHost))
   {
    if (Connect(remoteHost,"账号","密码"))
    {
        File.Copy("E:\\OpenForm.txt",@"\\192.168.1.21\file\chs.txt", true);//将OpenForm.txt内容copy到chs.txt中
    }
   }
        }
        public static bool Ping(string remoteHost)
        {

            bool Flag = false; //是否在线
             Ping ping = new Ping();
             PingReply pingReply = ping.Send(remoteHost);
             if (pingReply.Status == IPStatus.Success)
             {
                 Flag = true;
                  Console.WriteLine("当前在线，已ping通！");
             }
             else
             {
                  Console.WriteLine("不在线，ping不通！");
             }

            return Flag;
        }

        public static bool Connect(string remoteHost, string userName, string passWord)
        {
            if (!Ping(remoteHost))
            {
                return false;
            }
            bool Flag = true;
            Process proc = new Process();
            try
            {
                proc.StartInfo.FileName = "cmd.exe";
                proc.StartInfo.UseShellExecute = false;
                proc.StartInfo.RedirectStandardInput = true;
                proc.StartInfo.RedirectStandardOutput = true;
                proc.StartInfo.RedirectStandardError = true;
                proc.StartInfo.CreateNoWindow = true;
                proc.Start();
                string dosLine = @"net use \\" + remoteHost + " " + passWord + " " + " /user:" + userName + ">NUL";
                proc.StandardInput.WriteLine(dosLine);
                proc.StandardInput.WriteLine("exit");
                while (proc.HasExited == false)
                {
                    proc.WaitForExit(1000);
                }
                string errormsg = proc.StandardError.ReadToEnd();
                if (errormsg != "")
                {
                    Flag = false;
                }
                proc.StandardError.Close();
            }
            catch (Exception ex)
            {
                Flag = false;
            }
            finally
            {
                try
                {
                    proc.Close();
                    proc.Dispose();
                }
                catch
                {
                }
            }
            return Flag;
        }
