这里我给大家提供一个很实用的例子，就是在线发送ICQ信息。想一想我们在网页上直接给朋友发送ICQ信息，那是多么美妙的事情啊。呵呵，在吹牛啊，其实ICQ本来就有在线发送的代码，不过，这些都是AOL给你写好的代码，多没有意思啊。还是自已写的比较好，呵呵,废话少说，大家来看代码吧<% @ Page Language="C#" %><% @ Assembly Name="System.Net" %><% @ Import Namespace="System.Net" %><% @ Import Namespace="System.Net.Sockets" %><% @ Import Namespace="System.IO" %><% @ Import Namespace="System.Text" %><Script Language="C#" Runat="Server">public void Page_Load(Object src,EventArgs e){ICQ_Show.Text="如果提交后，在这里显示信息"; }public void Send_Click(Object sender,EventArgs e){string sendmsg;string commandmsg;//首先取得要发送的信息commandmsg = "from="+ICQ_Name.Text+"&fromemail="+ICQ_Email.Text+"&subject="; commandmsg += ICQ_Subject.Text+"&body="+ICQ_Message.Text+"&to="+ICQ_Number.Text commandmsg += "&Send=Send+Message";//然后就是组装全部的信息sendmsg="POST /scripts/WWPMsg.dll HTTP/1.1/r/n";sendmsg += "Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg,";sendmsg += " application/vnd.ms-excel,";sendmsg += " application/msword, application/vnd.ms-powerpoint, */*/r/n";sendmsg += "Accept-Language: zh-cn/r/n";sendmsg += "Content-Type: application/x-www-form-urlencoded/r/n";sendmsg += "Accept-Encoding: gzip, deflate/r/n";sendmsg += "User-Agent: Mozilla/4.0 (compatible; MSIE 5.01; Windows 95)/r/n";sendmsg += "Host: wwp.icq.com/r/n";sendmsg += "Content-Length: " + commandmsg.Length + "/r/n";sendmsg += "Connection: Keep-Alive/r/n/r/n";sendmsg += commandmsg + "/r/n/r/n";Byte[] arrMsg=Encoding.Default.GetBytes(sendmsg.ToCharArray());//需要发送的信息处理完毕//======下面就是发送这些信息=====//首先是建立一个TCPClient 对象TCPClient tcpc=new TCPClient();if(0==tcpc.Connect("wwp.icq.com",80)){Stream sm = tcpc.GetStream();sm.Write(arrMsg,0,sendmsg.Length);StreamReader sr=new StreamReader(tcpc.GetStream(),Encoding.Default);string strRev=sr.ReadLine();if(strRev.IndexOf("OK")!=-1){ICQ_Show.Text="ICQ消息发送成功";}else{ICQ_Show.Text="ICQ消息发送不成功";}}else{ICQ_Show.Text="ICQ消息发送不成功，无法联结ICQ服务器";}//关闭TCP联结tcpc.Close();}</script><html><meta http-equiv="Content-Language" content="zh-cn"><head><title></title></head><body><form runat="server" ><table><tr><td align=center colspan=2> <asp:Label id="ICQ_Show" runat="server" ForeColor="red" /></td></tr><tr><td></tr><tr><td align=center colspan=2>发送ICQ信息</td></tr><tr><td>您的ICQ号:</td><td><asp:TextBox id="ICQ_Number" runat="server" /></td></tr><tr><td>您的网名:</td><td><asp:TextBox id="ICQ_Name" runat="server" /></td></tr><tr><td>您的Email:</td><td><asp:TextBox id="ICQ_Email" runat="server" /></td></tr><tr><td>发送主题:</td><td><asp:TextBox id="ICQ_Subject" runat="server" /></td></tr><tr><td>发送内容:</td><td><asp:TextBox id="ICQ_Message" runat="server" /></td></tr><tr><td><asp:Button OnClick="Send_Click" Text="发送ICQ信息" RunAt="server" /></td></tr></table></form></body></html>
