這里我給大家提供一個很實用的例子，就是在線發送ICQ信息。想一想我們在網頁上直接給朋友發送ICQ信息，那是多么美妙的事情啊。呵呵，在吹牛啊，其實ICQ本來就有在線發送的代碼，不過，這些都是AOL給你寫好的代碼，多沒有意思啊。還是自已寫的比較好，呵呵,廢話少說，大家來看代碼吧
<% @ Page Langua
ge="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，在這里顯示信息";
} public void Send_Click(Object sender,EventArgs e)
{
string sendmsg;
string commandmsg;
//首先取得要發送的信息
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";
//然后就是組裝全部的信息
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());
//需要發送的信息處理完畢 //======下面就是發送這些信息=====
//首先是建立一個TCPClient 對象
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消息發送成功";
}
else
{
ICQ_Show.Text="ICQ消息發送不成功";
} }
else
{
ICQ_Show.Text="ICQ消息發送不成功，無法聯結ICQ服務器";
}
//關閉TCP聯結
tcpc.Close();
