如何让我的aspx Web方法返回的列表作为JSON对象？ [英] How do I make my aspx web method return the list as a JSON object?

问题描述

我有一个返回对象的Web方法。我需要这个对象转换为一个JSON对象，这样我可以通过我的Andr​​oid应用程序使用它。
因此，我的问题是，什么样的变化做我需要做，以返回下面的JSON对象？

I have a web method that returns a object. I need to convert this object to a JSON object so that i can consume it through my android application. Therefore my question is what changes do i need to make in order to return the following as JSON Object?

在ASPX code是如下：

The aspx code is as follows:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
using System.Web.Script.Services;

namespace WebService4
{
    /// <summary>
    /// Summary description for Service1
    /// </summary>
    [WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 
    // [System.Web.Script.Services.ScriptService]
    public class Service1 : System.Web.Services.WebService
    {

        [WebMethod]
        [ScriptMethod(ResponseFormat = ResponseFormat.Json)]
        public List<Vehicle> GetCustomerList()
        {
            Vehicle vehi = simpleCase();
            List<Vehicle> newL = new List<Vehicle> { vehi };
            return newL;

        }

        [WebMethod]
        public Vehicle simpleCase()
        {
            Vehicle obj = new Vehicle();
            obj.VehicleID = "KL-9876";
            obj.VehicleType = "Nissan";
            obj.VehicleOwner = "Sanjiva";
            return obj;
        }
    }

    //someObject.SomeMethod(obj);

    public class Vehicle
    {
        public string VehicleID { get; set; }
        public string VehicleType { get; set; }
        public string VehicleOwner { get; set; }
    }




}

推荐答案

您可以使用 HTTP ：//james.newtonking.com/projects/json-net.aspx ，序列化的列表，然后返回一个字符串

You could use http://james.newtonking.com/projects/json-net.aspx, serializing the list, and then returning a string.

您也可以使用C＃类的JavaScriptSerializer
