VB.NET遠程服務器返回錯誤：（405）方法不允許

Question

下面的代碼工作的一些網址，但有參數的一些其他URL返回錯誤：The remote server returned an error: (405) Method Not Allowed.

我的工作：

 Dim objHttpWebRequest As HttpWebRequest = Nothing 
     Dim objHttpWebResponse As HttpWebResponse = Nothing 
     Dim objRequestStream As Stream = Nothing 
     Dim objResponseStream As Stream = Nothing 
     Dim objXMLReader As XmlTextReader 

     Try 
     objHttpWebRequest = WebRequest.Create(URL) 

     'Start HttpRequest 
     objHttpWebRequest.Method = "POST" 
     objHttpWebRequest.ContentType = "application/xml" 

     'Get Stream Object 
     objRequestStream = objHttpWebRequest.GetRequestStream() 
     objRequestStream.Close() 

     'Start HTTP Response 
     objHttpWebResponse = objHttpWebRequest.GetResponse() 

     If objHttpWebResponse.StatusCode = HttpStatusCode.OK Then 
      objResponseStream = objHttpWebResponse.GetResponseStream() 
      objXMLReader = New XmlTextReader(objResponseStream) 

      Dim xmldoc As XmlDocument = New XmlDocument 
      xmldoc.Load(objXMLReader) 
      XMLResponse = xmldoc 
      objXMLReader.Close() 
     End If 

問題在我使用的方法中？或內容類型？

根據狀態碼，問題出在該方法中。並非所有的網址都可以響應POST請求。

Wikipedia狀態

405 Method Not Allowed

A request was made of a resource using a request method not supported by that resource; for example, using GET on a form which requires data to be presented via POST, or using PUT on a read-only resource.
