Asp.net XMLHTTP封装类(GET,Post发送和接收数据)

代码如下:

/**************************************************************** 
* 函数名称:SendCommand(SendMethod method, ST_Param p) 
* 功能说明:向远程发送URL和参数,接受返回信息(无乱码); 
* 参 数:method:xml发送方法,POST/Get 两种 
P:参数结构体 
public string Url; //远程URL 
public string Parameters; //参数 
public string Uid; //帐号 
public string Pwd; //号令 
* 调用示列: 
* using ebcnc; //引用空间名 
* XMLHTTP x = new XMLHTTP(); //创建设xmlhttp对像 
* XMLHTTP.ST_Param st = new XMLHTTP.ST_Param(); //创建参数数组 
* st.Parameters = ""; //url详细参数 
* st.Url = "http://www.baidu.com/"; //url 
* st.Uid = "" ; //帐号 
* st.Pwd = ""; //口令 
* string rn=””; //返回字符串 
* rn=x.SendCommand(XMLHTTP.SendMethod.POST, st); //获取返回信息 
* x.Dispose();
