如何通過WebClient請求使用動詞GET？

Question

我該如何更改WebClient請求的動詞？它似乎只允許/默認爲POST，即使在DownloadString的情況下。

 try 
     { 
      WebClient client = new WebClient();    
      client.QueryString.Add("apiKey", TRANSCODE_KEY); 
      client.QueryString.Add("taskId", taskId); 
      string response = client.DownloadString(TRANSCODE_URI + "task");     
      result = JsonConvert.DeserializeObject<Dictionary<string, dynamic>>(response); 
     } 
     catch (Exception ex) 
     { 
      result = null; 
      error = ex.Message + " " + ex.InnerException; 
     } 

而且小提琴手說：

POST http://someservice?apikey=20130701-234126753-X7384&taskId=20130701-234126753-258877330210884 HTTP/1.1

如果您使用HttpWebRequest，而不是您將獲得對呼叫的更多控制。您可以通過方法屬性，改變REST動詞（默認爲GET）

HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(HostURI); 
request.Method = "GET"; 
String test = String.Empty; 
using (HttpWebResponse response = (HttpWebResponse)request.GetResponse()) 
{ 
    Stream dataStream = response.GetResponseStream(); 
    StreamReader reader = new StreamReader(dataStream); 
    test = reader.ReadToEnd(); 
    reader.Close(); 
    dataStream.Close(); 
} 
DeserializeObject(test ...)
