/***************************************
* 對象名稱: SocketObj
* 功能說明: 遠程發送與接收
* 試用示例:
* using EC; //引用空間名
* string url = "218.75.111.74"; // URL也可以是(http://www.baidu.com/)這種形式
* int port = 8000; //端口
* string SendStr = "domainname/n"; //組織要發送的字符串
* SendStr += "check/n";
* SendStr += "entityname:domains/n";
* SendStr += "domainname:" + this.TextBox1.Text + "/n";
* SendStr += "./n";
* EBSocketObj o = new SocketObj(); //創建新對象
* o.Connection(url, port); //打開遠程端口
* o.Send(SendStr); //發送數據
* Response.Write(o.Recev()); //接收數據
* o.Dispose(); //銷毀對象
