WCF REST使用POST或PUT 400錯誤請求添加數據

HI 如何使用wcf rest架構添加數據。我不想使用channelfactory來調用我的方法。與用於GET的webrequest和webresponse類似。同樣的事情也給Ajax WebServiceProxy restInvoke 還是我總是要使用Webchannelfactory實施WCF REST使用POST或PUT 400錯誤請求添加數據

我通過以下

昏暗的URL的String =「http://localhost:4475/Service.svc/Entity/Add」昏暗REQ作爲WebRequest的得到一個400錯誤的請求=「WebRequest.Create（url） req.Method =」POST「 req.ContentType =」application/xml; charset = utf-8「 req.Timeout = 30000 req.Headers.Add（」SOAPAction「，url）

Dim xEle As XElement 
    xEle = <Entity xmlns:i="http://www.w3.org/2001/XMLSchema-instance"> 
       <Name>Entity1</Name> 
      </Entity> 

    Dim sXML As String = xEle .Value 
    req.ContentLength = sXML.Length 
    Dim sw As New System.IO.StreamWriter(req.GetRequestStream()) 
    sw.Write(sXML) 
    sw.Close() 

    Dim res as HttpWebResponse = req.GetResponse()

Sercice Contract is as follows 

    <OperationContract()> _ 
    <WebInvoke(Method:="PUT", UriTemplate:="Entity/Add")> _ 
    Function AddEntity(ByVal e1 As Entity)

 DataContract is as follows 

    <Serializable()> _ 
    <DataContract()> _ 
    Public Class Entity 
     private m_Name as String 
    <DataMember()> _ 
     Public Property Name() As String 
     Get 
     Return m_Name 
     End Get 
     Set(ByVal value As String) 
     m_Name = value 
     End Set 
     End Property 
    End Class

感謝
