如何調用刪除/放置方法從silverlight中休息服務

我得到了很多關於post的文章，並在休息服務中獲取方法，但我沒有得到任何好的put/delete方法。我創建了一個休息服務並試圖調用四個操作。獲取和發佈工作，但不是放入/刪除。我會在這裏提供我的代碼;如何調用刪除/放置方法從silverlight中休息服務

在WCF服務的Silverlight PUT和POST方法調用REST服務

const string uridel = 
       "http://localhost:50211/CustomerService.svc/deletecustomer/1"; 
const string uriput = 
       "http://localhost:50211/CustomerService.svc/modifycustomer/1"; 

client.DownloadStringCompleted += (s, ev) =>//delete method 
     { 
      XDocument xml = XDocument.Parse(ev.Result); 

      var Customer = from results in xml.Descendants 
               ("CustomerResponse") 
          select new CustomerResponse 
          { 
           CustomerId = Int32.Parse(results.Descendants 
               ("CustomerId").First().Value), 
          }; 


      int id = Customer.Select(w => w.CustomerId).FirstOrDefault(); 
      MessageBox.Show("result is :" + id); 
     }; 
     client.DownloadStringAsync(new Uri(uridel), "DELETE"); 


CustomerResponse cusres = new CustomerResponse();//put method 
     cusres.CustomerName = textBox1.Text; 
     cusres.CustomerPh = textBox2.Text; 
     DataContractSerializer dataContractSerializer = 
          new DataContractSerializer(typeof(CustomerResponse)); 
     MemoryStream memoryStream = new MemoryStream(); 
     dataContractSerializer.WriteObject(memoryStream, cusres); 
     string xmlData = Encoding.UTF8.GetString(memoryStream.ToArray(), 0, 
               (int)memoryStream.Length); 

     client.UploadStringCompleted += (s, ev) => 
     { 
      XDocument xml = XDocument.Parse(ev.Result); 

      var Customer = from results in xml.Descendants("CustomerResponse") 
          select new CustomerResponse 
          { 

           CustomerId = Int32.Parse(results.Descendants 
               ("CustomerId").First().Value), 
          }; 

      int id = Customer.Select(w => w.CustomerId).FirstOrDefault(); 
      MessageBox.Show("result is :" + id); 
      textBox1.Text = ""; 
      textBox2.Text = ""; 
     }; 
     client.Headers[HttpRequestHeader.ContentType] = "application/xml"; 
     client.UploadStringAsync(new Uri(uriput), "PUT", xmlData);

[OperationContract] 
    [WebInvoke(Method = "DELETE", 
       RequestFormat = WebMessageFormat.Xml, 
       ResponseFormat = WebMessageFormat.Xml, 
       BodyStyle = WebMessageBodyStyle.Bare, 
       UriTemplate = "deletecustomer/{id}")] 
    CustomerResponse DeleteCustomer(string id); 


[OperationContract] 
    [WebInvoke(Method = "PUT", 
       RequestFormat = WebMessageFormat.Xml, 
       ResponseFormat = WebMessageFormat.Xml, 
       BodyStyle = WebMessageBodyStyle.Bare, 
       UriTemplate = "modifycustomer/{id}")] 
    CustomerResponse ModifyCustomer(string id,CustomerResponse cusres);

對於刪除我得到一個例外，該服務器沒有發現針對put方法我的錯誤得到了像此請求不支持指定的方法。任何人都可以提出錯誤的地方..或建議好的文章，可以使用put和delete方法在silverlight中消耗？

步驟1：在Silverlight應用程序中檢查您是否在App（）構造函數的App.xaml.cs中添加了以下行。

HttpWebRequest.RegisterPrefix("http://", WebRequestCreator.ClientHttp); 
HttpWebRequest.RegisterPrefix("https://", WebRequestCreator.ClientHttp);

第2步：

<?xml version="1.0" encoding="utf-8"?> 
<access-policy> 
    <cross-domain-access> 
    <policy> 
    <allow-from http-request-headers="*" http-methods="*">  
     <domain uri="*"/> 
    </allow-from> 
    <grant-to> 
     <resource path="/" include-subpaths="true"/> 
    </grant-to> 
    </policy> 
</cross-domain-access> 
</access-policy>

保存XML爲「clientaccesspolicy.xml」你的服務主體項目之下。
