將Json傳遞給安靜的WCF

Question

我正在發送（發佈）Json數據給wcf服務。

---

public interface IRegisterEmployee 
    { 

     [OperationContract] 
     [WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, BodyStyle=WebMessageBodyStyle.Bare, ResponseFormat=WebMessageFormat.Json, UriTemplate = "AddEmployee")] 
     bool ProcessEmployee(Employee emps); 
    } 

---

[DataContract] 
    public class Employee 
    { 
     [DataMember] 
     public Emp[] emps { get; set; } 

    } 

---

DataContract] 
    public class Emp 
    { 
     [DataMember] 
     public string FName { get; set; } 
     [DataMember] 
     public string joinDate {get; set; } 
     [DataMember] 
     public Contact[] contacts {get; set; } 

    } 

---

DataContract] 
    public class Contact 
    { 
     [DataMember] 
     public string key { get; set; } 
     [DataMember] 
     public string value {get; set; } 

    }

public class RegisterEmployee : IRegisterEmployee 
    { 
     public bool ProcessEmployee(Employee emps) 
     { 
      //do some processing 
      return true; 

     } 

當我使用提琴手發送輸入數據（JSON），在調試模式下，我看到輸入（emps）包含Emp（即FName和joinDate）的值，但是聯繫人（鍵值）的數據即將到來儘管它存在於輸入中，儘管它是空的。任何想法爲什麼它是空的？如果我用soap/xml測試這個，我可以看到所有的輸入數據，它工作正常。

你打電話給你的服務？ 我試圖在本地複製的問題，我能得到一些數據調用服務的方式如下：

string sURL = "http://localhost:13104/RegisterEmployee.svc/AddEmployee"; 

     var employee = new Employee 
     { 
      emps = new Emp[1] { 
       new Emp { 
        FName = "MyFName", 
        joinDate = "12/01/2012", 
        contacts = new WcfService1.Contact[1] 
        { 
         new WcfService1.Contact { key = "myKey", value="myVailue" } 
        } 
       } 
      } 
     }; 

     var json = Newtonsoft.Json.JsonConvert.SerializeObject(employee); 

     ASCIIEncoding encoding = new ASCIIEncoding(); 
     byte[] byte1 = encoding.GetBytes (json); 

     WebRequest wrGETURL; 
     wrGETURL = WebRequest.Create(sURL); 
     wrGETURL.Method = "POST"; 
     wrGETURL.ContentType = @"application/json; charset=utf-8"; 
     wrGETURL.ContentLength = byte1.Length; 
     Stream requestStream = wrGETURL.GetRequestStream();    
     requestStream.Write(byte1, 0, byte1.Length); 
     requestStream.Close(); 


     HttpWebResponse webresponse = wrGETURL.GetResponse() as HttpWebResponse; 

     Encoding enc = System.Text.Encoding.GetEncoding("utf-8"); 
     // read response stream from response object 
     StreamReader loResponseStream = new StreamReader(webresponse.GetResponseStream(), enc); 
     // read string from stream data 
     string strResult = loResponseStream.ReadToEnd(); 
     // close the stream object 
     loResponseStream.Close(); 
     // close the response object 
     webresponse.Close(); 
     // assign the final result to text box 
     Response.Write(strResult);
