本文介绍了如何将自定义对象传递给WCF服务的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 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 Implementationpublic 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 b $ bClient application code goes as followsstatic 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 removeBodyStyle = 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. 这篇关于如何将自定义对象传递给WCF服务的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
