问题描述

我只是使用 XmlWriter 创建一些 XML 以在 HTTP 响应中发回.您将如何创建 JSON 字符串.我假设您只是使用 stringbuilder 来构建 JSON 字符串，然后它们将您的响应格式化为 JSON?

I just used the XmlWriter to create some XML to send back in an HTTP response. How would you create a JSON string. I assume you would just use a stringbuilder to build the JSON string and them format your response as JSON?

推荐答案

您可以使用 JavaScriptSerializer 类，检查这篇文章 构建一个有用的扩展方法.

You could use the JavaScriptSerializer class, check this article to build an useful extension method.

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();
