服务端代码与接口页面post交互

webclient对象实现

WebClient wb = new WebClient();                        

System.Collections.Specialized.NameValueCollection varPost = new System.Collections.Specialized.NameValueCollection();  

参数对象，对方页面接收                                 

varPost.Add("a", a);                        

varPost.Add("b", b);

varPost.Add("c", c);

byte[] RemoteInfo = wb.UploadValues(requestUrl, "POST", varPost);
