如何将自定义对象传递给WCF服务 [英] How to pass a custom object to WCF service

问题描述

大家好，



我试图通过客户端应用程序将复杂对象传递给WCF服务。

当我调试时代码，我看到对象即将为空。



我尝试了以下代码。



界面方法

Hi All,

I am trying to pass a complex object to WCF service through a Client Application.
When i debug the code, I see object is coming as null.

I tried the following code.

Interface method

[OperationContract]
        [WebInvoke(Method = "POST",
            ResponseFormat = WebMessageFormat.Json,
            BodyStyle = WebMessageBodyStyle.WrappedRequest,
            UriTemplate = "Testmethod/JSON/")]
        bool TestmethodJson(Complain comp);

服务实施

Service Implementation

public bool TestmethodJson(Complain comp)
        {
            if (comp != null)
            {
             //code goes here  
                return true;
            }
            else
            {
              //code goes here
                return false;
            } 

客户端应用程序代码如下 < br $> b $ b

Client application code goes as follows

static void Main(string[] args)
        {
            Complain comp = new Complain()
            {
                CompainType = "type1",
                CompainBody = "Body1"
            };

             //JavaScriptSerializer serializer = new JavaScriptSerializer();

            string output = JsonConvert.SerializeObject(comp);

            //string output = serializer.Serialize(complain);

             string strUri = "http://localhost:35798/NavGAT.svc/Testmethod/JSON/";
            Uri uri = new Uri(strUri);
            WebRequest request = WebRequest.Create(uri);
            request.Method = "POST";
            request.ContentLength = output.Length;
            request.ContentType = "application/json; charset=utf-8";

          //  JavaScriptSerializer jsonSerializer = new JavaScriptSerializer();
            string serOut = JsonConvert.SerializeObject(comp);
          //  string serOut = jsonSerializer.Serialize(complain);

            using (StreamWriter writer = new StreamWriter(request.GetRequestStream()))
            {
                writer.Write(serOut);
            }

            WebResponse responce = request.GetResponse();
            Stream reader = responce.GetResponseStream();

            StreamReader sReader = new StreamReader(reader);
            string outResult = sReader.ReadToEnd();
            sReader.Close();
        }

我可以从客户端调用服务但是对象是null。请让我知道问题所在通过复杂的对象服务。





在此先感谢.. :)

I am able to call a service from client but object comes as null.Please let me know the problem in passing complex object service.


Thanks in Advance.. :)

推荐答案

请确保您拥有带有DataContract属性的Complain实体类声明，并且CompainType和CompainBody必须具有DataMemeber属性。

Please ensure you have Complain entity class declaration with DataContract attribute over it and CompainType and CompainBody must have DataMemeber attribute over it.

using System.Runtime.Serialization;

 [DataContract]
    public class Complain 
    {
        #region Private Members
        private string _CompainBody ;
        private string _CompainType ;
        #endregion

        #region Public Members

        [DataMember]
        public int CompainBody 
        {
            get { return _CompainBody ; }
            set { _CompainBody = value; }
            }
        [DataMember]
        public string CompainType 
        {
            get { return _CompainType ; }
            set { _CompainType = value; }
        }

        }
}

你有BodyStyle作为WrappedRequest，所以你需要做 -

删除

You have BodyStyle as WrappedRequest,so you need to do-
Either remove

BodyStyle = WebMessageBodyStyle.WrappedRequest

或传递你的对象，如

{
    "comp": {
        "ComplainType": "1",
        "ComplainBody": "message"
    }
}

这就是你如何在对象中看到值。

That's how you can see values in in object.
