C#调用net.exe发送消息

默认情况下，WinXP
SP2的Messenger服务是禁止的，如果需要使用必须先启动该服务。

using System.Diagnostics;

//发消息

private void NetSendMsg(string strIp, string
strHostname, string strMsg)

{

try

{

Process sendprocess =new Process();

sendprocess.StartInfo.FileName = "net.exe";

sendprocess.StartInfo.Arguments = "send " + strIp + " " + strMsg;

sendprocess.StartInfo.UseShellExecute = false;

sendprocess.StartInfo.RedirectStandardOutput = true;

sendprocess.StartInfo.RedirectStandardError = true;

sendprocess.StartInfo.CreateNoWindow = true;

sendprocess.Start();
string strSend =
sendprocess.StandardOutput.ReadToEnd();

if (strSend.IndexOf("消息已经送到
"+strIp+"。") != -1)

{

lb_Info.Items.Add(DateTime.Now.ToLongTimeString() + "发消息到 " +
strHostname + ":" + strMsg);

}

else

{

lb_Info.Items.Add("发消息到" + strHostname +
"失败!"+DateTime.Now.ToLongTimeString());

}

}

catch(Exception ex)

{

lb_Info.Items.Add(ex.Message+DateTime.Now.ToLongTimeString()+"发消息到" +
strHostname + "失败!");

}

}
