無法連線，因為目標電腦拒絕連線。
protected void Page_Load(object sender, EventArgs e)
{
this.TextBox1.Text += socket("localhost");
}
public String socket(string server)//
http://msdn2.microsoft.com/zh-tw/library/system.net.sockets.addressfamily(VS.80).aspx
{
Encoding ASCII = Encoding.ASCII;
string Get = "GET / HTTP/1.1\r\nHost: " + server + "\r\nConnection:
Close\r\n\r\n";
Byte[] ByteGet = ASCII.GetBytes(Get);
Byte[] RecvBytes = new Byte[256];
String strRetPage = null;
Socket s = null;
IPEndPoint hostEndPoint;
IPAddress hostAddress = null;
int conPort = 80;

}
Int32 bytes = s.Receive(RecvBytes, RecvBytes.Length, 0);
strRetPage = "Default HTML page on " + server + ":\r\n";
strRetPage = strRetPage + ASCII.GetString(RecvBytes, 0, bytes);
while (bytes > 0)
{
bytes = s.Receive(RecvBytes, RecvBytes.Length, 0);
strRetPage = strRetPage + ASCII.GetString(RecvBytes, 0, bytes);
}
return "strRetPage";
}
