C# Json序列化List

Question

我在 .Net Json 序列化方面遇到了一点问题我有一个带有字符串列表的类，我需要将它序列化为属性，例如:

原创:

class:
kid{
   int age;
   String name;
   List[String] toys;
}

结果:

{
    "age":10,
    "name": Jane,
    "toys":["one", "two", "three"]
}

我需要

{
    "age":10,
    "name": Jane,
    "toy_1": "one", 
    "toy_2": "two",
    "toy_3": "three"  
}

是因为api。有什么办法吗？

Answer 1

这是一个不假设玩具数量的动态解决方案:

    public class kid
    {
        public int age;
        public String name;
        public List<String> toys;

        public string ApiCustomView
        {
            get
            {
                Dictionary<string, string> result = new Dictionary<string, string>();
                result.Add("age", age.ToString());
                result.Add("name", name);
                for (int ii = 0; ii < toys.Count; ii++)
                {
                    result.Add(string.Format("toy_{0}", ii), toys[ii]);
                }
                return result.ToJSON();
            }
        }
    }

用法:

    static void Main(string[] args)
    {
        var k = new kid { age = 23, name = "Paolo", toys = new List<string>() };
        k.toys.Add("Pippo");
        k.toys.Add("Pluto");

        Console.WriteLine(k.ApiCustomView);
        Console.ReadLine();
    }

它使用您可以在此处找到的扩展名:How to create JSON string in C#

namespace ExtensionMethods
{
    public static class JSONHelper
    {
        public static string ToJSON(this object obj)
        {
            JavaScriptSerializer serializer = new JavaScriptSerializer();
            return serializer.Serialize(obj);
        }

        public static string ToJSON(this object obj, int recursionDepth)
        {
            JavaScriptSerializer serializer = new JavaScriptSerializer();
            serializer.RecursionLimit = recursionDepth;
            return serializer.Serialize(obj);
        }
    }
}
