简单的消息发送小程序

借用命令行发送消息机制实现，十分简单，废话不说，贴代码吧using System.Runtime.InteropServices;

public int SendMessage(string sFrom,string sTo,string sMessage)

[DllImport ("Netapi32", CharSet=CharSet.Unicode)]
public static extern int NetMessageBufferSend( string servername, string msgname, string fromname, string buf, int buflen);

//调用举例
int a = SendMessage(Request.UserHostName.ToString(),tbx_sendto.Text.Trim(),tbx_message.Value.ToString());
