c＃WCF JSON POST - （400）错误请求

Question

我尝试了一切！

我总是得到一个＆＃34;（400）错误请求＆＃34;我尝试从客户端调用WCF服务时出错。

我想通过JSON发送给服务器a＆＃39;用户＆＃39;类

我的代码：

计算值

 [OperationContract]
 [WebInvoke(Method="POST",
        RequestFormat=WebMessageFormat.Json,
        ResponseFormat=WebMessageFormat.Json,
        UriTemplate = "/UplaodData")]
void PostUser(Users user);

界面ICalc

 public void PostUser(Users user)
 {
     int userId = user.id;
     .....
 }

的Web.config

客户端

private void btnAdd_Click(object sender, EventArgs e)
{
    if(ValidateChildren(ValidationConstraints.Enabled))
    {
        var user = new Users();
        user.id = 1;
        user.birthday = new DateTime(2009,1,1);
        WebClient Proxy = new WebClient();
        Proxy.Headers["Content-type"] = "application/json";
        MemoryStream ms = new MemoryStream();
        var serializerToUpload = new DataContractJsonSerializer(typeof(Users));
        serializerToUpload.WriteObject(ms, user);
        proxy.UploadData(basicURL + "UplaodData", "POST", ms.ToArray());
    }
}

修改

private string basicURL = string.Format("http://localhost:20524/finalProjectServer/Service.svc/");
private WebClient proxy = new WebClient();
