Asp.net XMLHTTP 基类 (GET,Post发送和接收数据)

1.   
2. /****************************************************************
3.  * 函数名称：SendCommand(SendMethod method, ST_Param p)
4.  * 功能说明：向远程发送URL和参数,接受返回信息(无乱码); 
5.  * 参    数：method:xml发送方法,POST/Get 两种
6.       P:参数结构体
7.               public string Url; //远程URL
8.               public string Parameters; //参数
9.               public string Uid; //帐号
10.               public string Pwd; //号令
11.  * 调用示列：
12.  *           using ebcnc;    //引用空间名 
13.  *           XMLHTTP x = new XMLHTTP(); //创建设xmlhttp对像
14.  *           XMLHTTP.ST_Param st = new XMLHTTP.ST_Param(); //创建参数数组
15.  *           st.Parameters = "";  //url详细参数
16.  *           st.Url = "http://www.baidu.com"; //url
