ASP.NET发送ICQ消息DIY

<br> 
<br> 
<br> 
　　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<br> 
<br> 
＜% @ Page Language="C#" %＞<br> 
＜% @ Assembly Name="System.Net" %＞<br> 
＜% @ Import Namespace="System.Net" %＞<br> 
＜% @ Import Namespace="System.Net.Sockets" %＞<br> 
＜% @ Import Namespace="System.IO" %＞<br> 
＜% @ Import Namespace="System.Text" %＞<br> 
<br> 
＜Script Language="C#" Runat="Server"＞<br> 
public void Page_Load(Object src,EventArgs e)<br> 
{<br> 
ICQ_Show.Text="如果提交后，在这里显示信息"; <br> 
}<br> 
<br> 
public void Send_Click(Object sender,EventArgs e)<br> 
{<br> 
string sendmsg;<br> 
string commandmsg;<br> 
file://首先取得要发送的信息<br> 
commandmsg = "from="+ICQ_Name.Text+"&fromemail="+ICQ_Email.Text+"&subject="; <br> 
commandmsg += ICQ_Subject.Text+"&body="+ICQ_Message.Text+"&to="+ICQ_Number.Text <br> 
commandmsg += "&Send=Send+Message";<br> 
file://然后就是组装全部的信息<br> 
sendmsg="POST /scripts/WWPMsg.dll HTTP/1.1\r\n";<br> 
sendmsg += "Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg,";<br> 
sendmsg += " application/vnd.ms-excel,";<br> 
sendmsg += " application/msword, application/vnd.ms-powerpoint, */*\r\n";<br> 
sendmsg += "Accept-Language: zh-cn\r\n";<br> 
sendmsg += "Content-Type: application/x-www-form-urlencoded\r\n";<br> 
sendmsg += "Accept-Encoding: gzip, deflate\r\n";<br> 
sendmsg += "User-Agent: Mozilla/4.0 (compatible; MSIE 5.01; Windows 95)\r\n";<br> 
sendmsg += "Host: wwp.icq.com\r\n";<br> 
sendmsg += "Content-Length: " + commandmsg.Length + "\r\n";<br> 
sendmsg += "Connection: Keep-Alive\r\n\r\n";<br> 
sendmsg += commandmsg + "\r\n\r\n";<br> 
<br> 
Byte[] arrMsg=Encoding.Default.GetBytes(sendmsg.ToCharArray());<br> 
file://需要发送的信息处理完毕<br> 
<br> 
file://======下面就是发送这些信息=====<br> 
file://首先是建立一个TCPClient 对象<br> 
TCPClient tcpc=new TCPClient();<br> 
if(0==tcpc.Connect("wwp.icq.com",80))<br> 
{<br> 
Stream sm = tcpc.GetStream();<br> 
sm.Write(arrMsg,0,sendmsg.Length);<br> 
StreamReader sr=new StreamReader(tcpc.GetStream(),Encoding.Default);<br> 
string strRev=sr.ReadLine();<br> 
if(strRev.IndexOf("OK")!=-1)<br> 
{<br> 
ICQ_Show.Text="ICQ消息发送成功";<br> 
}<br> 
else<br> 
{<br> 
ICQ_Show.Text="ICQ消息发送不成功";<br> 
}<br> 
<br> 
}<br> 
else<br> 
{<br> 
ICQ_Show.Text="ICQ消息发送不成功，无法联结ICQ服务器";<br> 
}<br> 
file://关闭TCP联结<br> 
tcpc.Close();<br> 
}<br>
