第一步，首先定义契约，创建一个接口
第二步实现接口
using System; using System.Collections.Generic; using System.Linq; using System.Runtime.Serialization; using System.ServiceModel; using System.ServiceModel.Activation; using System.ServiceModel.Web; using System.Text; namespace WcfService1 { [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] public class JsonWCF:IJoonService { // 要使用 HTTP GET，请添加 [WebGet] 特性。(默认 ResponseFormat 为 WebMessageFormat.Json) // 要创建返回 XML 的操作， // 请添加 [WebGet(ResponseFormat=WebMessageFormat.Xml)]， // 并在操作正文中包括以下行: // WebOperationContext.Current.OutgoingResponse.ContentType = "text/xml"; // 在此处添加更多操作并使用 [OperationContract] 标记它们 [WebInvoke(ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.WrappedRequest)] public JsonResult HelloWorld() { JsonResult jr = new JsonResult(); jr.Address = "tt"; jr.Name = "rrr"; jr.Phone = "78"; // List<Admin> list = me.Admin.ToList(); return jr; } public string HelloWorld2() { return "啊啊"; } public List<JsonResult> HelloWorld3() { List<JsonResult> list = new List<JsonResult>(); JsonResult jr = new JsonResult(); jr.Address = "tt"; jr.Name = "rrr"; jr.Phone = "78"; JsonResult j = new JsonResult(); j.Address = "yy"; j.Name = "uu"; j.Phone = "000"; list.Add(jr); list.Add(j); return list; } } }
第三步另一个项目调用wcf服务，并解析json对象

2009-10-22后记知道那个“d”是干嘛滴了,不过一直没有更新,为了以后复习,备注在此 [OperationContract( Name = "DoWork4" )] [WebInvoke( Method = "POST", BodyStyle = WebMessageBodyStyle.Wrapped, RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, UriTemplate = "/DoWork4" )] [return: MessageParameter( Name = "e" )] public Person DoWork4( [MessageParameter( Name = "e" )] Person e ) { // 在此处添加操作实现 return new Person() { Age = 100, Name = "远始天尊" }; }加重的两行,[return: MessageParameter( Name = "e" )]这一行影响返回JSON对象时的名称,就是传说中的"d",此时被声明为"e"了后一行 public Person DoWork4( [MessageParameter( Name = "e" )] Person e ) {这个影响的是方法接收JSON对象的参数名称,也被改为"e"了,呵呵
