使用c＃将json字符串数据传递给Rest服务（POST方法）

Question

在我的项目中，我必须将动态Json字符串传递给WCF Rest服务。这里的输入/输出都应该是Json格式。我正在使用服务器端代码传递我的数据。这是我的代码

在testpage.aspx.cs页面

    string json = "{\"sjSonData\":[{"
                             + "\"log_Id\" : 0,"
                             + "\"user_Id\" : 1249,"
                             + "\"session_key\" : \"dvnoewcdw\","
                             + "\"app_id\" : 1,"
                             + "\"app_version\" :\"1.2.7\","
                             + "\"app_isOnline\" : true,"
                             + "\"app_dateTimeZone\" : \"1997-07-16T19:20:30+01:00\","
                             + "\"log_typeId\" : 1,"
                             + "\"log_description\" : \"valid\""
                         + "},"
                         + "{"
                             + "\"log_Id\" : 1,"
                             + "\"user_Id\" : 1249,"
                             + "\"session_key\" : \"dvnoewcdw\","
                             + "\"app_id\" : 1,"
                             + "\"app_version\" : \"1.2.7\","
                             + "\"app_isOnline\" : true,"
                             + "\"app_dateTimeZone\" : \"1997-07-16T19:20:30+01:00\""
                             +"}]}";

const string url = "http://localhost/RestServiceImpl.svc/jsoninputdata";

       //create an HTTP request to the URL that we need to invoke
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);                
            request.ContentType = "application/json; charset=utf-8"; //set the content type to JSON
            request.Method = "POST"; //make an HTTP POST

            using (var streamWriter = new StreamWriter(request.GetRequestStream()))
            {
                //initiate the request
                JavaScriptSerializer serializer = new JavaScriptSerializer();
                var resToWrite = serializer.Deserialize<Dictionary<string, object>>(json);
                streamWriter.Write(restoWrite);
                streamWriter.Flush();
                streamWriter.Close();
            }

            // Get the response.
            WebResponse response = request.GetResponse();                
            var streamReader = new StreamReader(response.GetResponseStream());                
            var result = streamReader.ReadToEnd();

我是WCF服务的新手。我不知道如何将此数据传递给Rest服务。在这里，我的输入数据在每次通话时都有所不同。

休息服务代码

[ServiceContract]
 public interface IRestServiceImpl
 {
   [OperationContract]
        [WebInvoke(Method = "POST",
            ResponseFormat = WebMessageFormat.Json,
            RequestFormat = WebMessageFormat.Json,
            BodyStyle = WebMessageBodyStyle.Bare,
            UriTemplate = "jsoninputdata")]
    string jsoninputdata(List<Dictionary<string, object>> rData);
 }    

 public class RestServiceImpl : IRestServiceImpl
 {    
      public jSonResponseData jsoninputdata(List<Dictionary<string, object>> rData)
      {       
          string json = JsonConvert.SerializeObject(rData);
          //Do my stuff here.....    
          return ojSonRes; // Here i need to return my output mentioned below
      }
  }

我需要返回如下所示的数据（输出），

条件1：如果两者都保存在db中而没有任何错误，

{"sjSonData":[{
  "success":true
}]}

条件2：假设任何一个数据都无法保存在数据库中，那么

{"sjSonData":[
{
"log_Id":1,
"success":false
},
{
 "log_Id":2,
 "success":true
}
]}

现在我得到了结果，

{"sjSonData":"{}"}

我做错了什么!!!!!还请解释我在web.config文件中要做的所有更改。
