模擬POST傳參 並接收返回值

            System.Net.WebClient WebClientObj = new System.Net.WebClient();
            System.Collections.Specialized.NameValueCollection PostVars = new System.Collections.Specialized.NameValueCollection();
            
            PostVars.Add("參數名", "參數值");//參數
            PostVars.Add("參數名", "參數值");//參數


            try
            {
                byte[] byRemoteInfo = WebClientObj.UploadValues("請求地址", "POST", PostVars);//請求地址,傳參方式,參數集合

                string sRemoteInfo = System.Text.Encoding.Default.GetString(byRemoteInfo);//獲取返回值


            }
            catch
            { }
