第一種情況是告訴Server你正在以Json方式呼叫Request，如：
 

using (WebClient webClient = new WebClient())
{
    webClient.Encoding = Encoding.UTF8;
    webClient.Headers.Add(HttpRequestHeader.ContentType, "application/json");
    //webClient.Headers.Add("authorization", "token {apitoken}");
    PostData postData = new PostData() { UserId= "Eddie",  SystemId="CRM" };
    string json = JsonConvert.SerializeObject(postData);
    var result = webClient.UploadString("https://jsonbin.org/yowko/test", json);
}

{ UserId: 'Eddie', SystemId:'CRM' }

第二種情況是告訴Web Server你正在對URL中參數編碼Reuqest

，如：
 

UserId=Eddie&SystemId=CRM

string url= "";
using (WebClient client = new WebClient())
{
    System.Collections.Specialized.NameValueCollection postData = 
        new System.Collections.Specialized.NameValueCollection()
       {
              { "para1", para1},  
              { "para2", para2},
              { "para3", para3}
       };
    string pagesource = Encoding.UTF8.GetString(client.UploadValues(url, postData));
}

 

        //ReturnApiData returnFinalApiData = WebAPIModel.GetFinalApi(FinelApiUrl, FinalApiUrlParam);
        //ReturnHotelFinalData returnFinalData = WebAPIModel.GetSuccessData<ReturnFinalData>(returnFinalApiData );  
        public static TResult HttpGet<TParam, TResult>(string address, TParam t)
        {
            string url = string.Format("{0}?{1}", address, ClassConvertToParam(t));
            //HttpContext.Current.Response.Write(url);
            using (WebClient wc = new WebClient() { Encoding = Encoding.UTF8 })
            {
                string srcString = wc.DownloadString(url);
                TResult result = JsonConvert.DeserializeObject<TResult>(srcString);
                return result;
            }
        }

            string postData = "";

            if (t.GetType() == typeof(String))
            {
                postData = t.ToString();
            }
            else
            {
