如果你需要复杂的结果(嵌入)，创建你自己的结构:

class templateRequest
{
    public String[] registration_ids;
    public Data data;
    public class Data
    {
        public String message;
        public String tickerText;
        public String contentTitle;
        public Data(String message, String tickerText, string contentTitle)
        {
            this.message = message;
            this.tickerText = tickerText;
            this.contentTitle = contentTitle;
        }                
    };
}

然后通过调用获取JSON字符串

List<String> ids = new List<string>() { "id1", "id2" };
templateRequest request = new templeteRequest();
request.registration_ids = ids.ToArray();
request.data = new templateRequest.Data("Your message", "Your ticker", "Your content");

string json = new JavaScriptSerializer().Serialize(request);

结果是这样的:

json = "{\"registration_ids\":[\"id1\",\"id2\"],\"data\":{\"message\":\"Your message\",\"tickerText\":\"Your ticket\",\"contentTitle\":\"Your content\"}}"

希望能有所帮助!

如果您试图创建一个web服务，通过JSON向web页面提供数据，请考虑使用ASP。. NET Ajax工具包:

http://www.asp.net/learn/ajax/tutorial-05-cs.aspx

它会自动将你通过webservice服务的对象转换为json，并创建你可以用来连接到它的代理类。

您可以使用JavaScriptSerializer类来构建一个有用的扩展方法。

文章中的代码:

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);
        }
    }
}

用法:

using ExtensionMethods;

...

List<Person> people = new List<Person>{
                   new Person{ID = 1, FirstName = "Scott", LastName = "Gurthie"},
                   new Person{ID = 2, FirstName = "Bill", LastName = "Gates"}
                   };


string jsonString = people.ToJSON();

{

    public Data data;
    public class Data
    {
        public String message;
        public String tickerText;
        public String contentTitle;
        public Data(String message, String tickerText, string contentTitle)
        {
            this.message = message;
            this.tickerText = tickerText;
            this.contentTitle = contentTitle;
        }                
    };
}

string json = new JavaScriptSerializer().Serialize(request);

看看http://www.codeplex.com/json/上的json-net。aspx项目。为什么要重新发明轮子?

包括:

使用System.Text.Json;

然后像这样序列化你的object_to_serialize: JsonSerializer.Serialize (object_to_serialize)
