using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.ServiceModel;
using System.ServiceModel.Activation;
using System.ServiceModel.Web;
namespace WcfService1
{
//一定要取个名字，不然客户端访问不到
[ServiceContract(Namespace = "ymn", Name = "J")]
public interface IJoonService
{
//暴漏方法，并且返回json格式数据
[OperationContract]
JsonResult HelloWorld();
[OperationContract]
string HelloWorld2();
[OperationContract]
List<JsonResult> HelloWorld3();
}
}
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
