asp.net XMLHTTP encapsulation class (Get,post send and receive data) _ Practical Tips

Copy Code code as follows:

/****************************************************************
* Function Name: SendCommand (Sendmethod method, St_param p)
* Function Description: Send the URL and parameters to the remote, accept the return information (no garbled);
* Parameter: Method:xml send method, post/get two kinds
P: Parametric structural body
public string Url; Remote URL
public string Parameters; Parameters
public string Uid; Account
public string Pwd; Command
* Call Columns:
* Using EBCNC; Reference Space Name
* XMLHTTP x = new XMLHTTP (); The XMLHTTP of creating construction
* XMLHTTP. St_param st = new XMLHTTP. St_param (); Creating an array of parameters
* St. Parameters = ""; URL Detail Parameters
* St. URL = "http://www.baidu.com/"; Url
* St. Uid = ""; Account
* St. PWD = ""; Password
* String rn= ""; return string
* Rn=x.sendcommand (XMLHTTP. Sendmethod.post, ST); Get return information
* X.dispose ();
