POST请求

Question

我已经开发了REST WCF服务方法如下：

[OperationContract] 
    [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.WrappedRequest, RequestFormat = WebMessageFormat.Xml, ResponseFormat = WebMessageFormat.Xml, UriTemplate = "/Details")] 
    DetailData GetDetails(TestData requst); 


[DataContract] 
public class TestData 
{ 
    [DataMember] 
    public string DetailData { get; set; } 
} 

现在我尝试使用下面的客户端代码来调用服务：

ASCIIEncoding encoding = new ASCIIEncoding(); 
    string testXml = "<TestData>" + 
         "<DetailData>" + 
          "4000" + 
         "</DetailData>" + 
        "</TestData>"; 

string postData = testXml.ToString(); 
byte[] data = encoding.GetBytes(postData); 
string url = "http://localhost/WCFRestService.svc/bh/Details"; 
string strResult = string.Empty; 

// declare httpwebrequet wrt url defined above 
HttpWebRequest webrequest = (HttpWebRequest)WebRequest.Create(url); 
// set method as post 
webrequest.Method = "POST"; 
// set content type 
webrequest.ContentType = "text/xml"; 
// set content length 
webrequest.ContentLength = data.Length; 
// get stream data out of webrequest object 
Stream newStream = webrequest.GetRequestStream(); 
newStream.Write(data, 0, data.Length); 
newStream.Close(); 

//Gets the response 
WebResponse response = webrequest.GetResponse(); 
//Writes the Response 
Stream responseStream = response.GetResponseStream(); 

StreamReader sr = new StreamReader(responseStream); 
string s = sr.ReadToEnd(); 

我收到以下错误：

“远程服务器返回错误：（400）错误的请求”

我可以成功调用另一种使用“GET”动词的服务方法。但上面的客户端代码使用“POST”动词调用服务不起作用。我想，我在客户端代码中丢失了一些东西。 可能是什么问题？

尝试改变

WebMessageBodyStyle.WrappedRequest 

到

WebMessageBodyStyle.Bare
