Json.NET 在返回 json 序列化字符串时添加反斜杠 [英] Json.NET adding backslash while returning json serialized string

问题描述

我正在尝试使用 Json.NET 将列表序列化为 json 字符串，但返回字符串中包含反斜杠，这反过来导致 json 解析失败.

I am trying to serialize a list to json string using Json.NET but the return string has backslash within it, which in turn is failing a json parsing.

var x = from d in entities.Books.ToList()
        select new
        {
            ID = d.ID,
            BookName = d.BookName
        };
return JsonConvert.SerializeObject(x.ToList());

以上代码返回

"[{"ID":1,"BookName":"MVC Music Store - Tutorial - v3.0"},{"ID":2,"BookName":"Pro.ASP.NET.MVC.3.Framework"},{"ID":3,"BookName":"Application Architecture Guide v2"},{"ID":4,"BookName":"Gang of Four Design Patterns"},{"ID":5,"BookName":"CS4 Pocket Reference"}]"

所有 JSON 解析失败.我怎样才能删除这些.

which fails all JSON parsing. How can I remove these.

推荐答案

没有.它没有

class Program
{
    class Book
    {
        public int ID;
        public string BookName;
    }

    static void Main()
    {
        var books = new List<Book> { new Book { ID = 1, BookName = "A" }, new Book { ID = 2, BookName = "B" } };

        var x = from d in books
        select new
        {
            ID = d.ID,
            BookName = d.BookName
        };

        string str = JsonConvert.SerializeObject(x.ToList());
        Console.WriteLine(str);
    }
}

可能有两个问题:

A) 您正在查看调试器的结果.要检查这一点，请将 JsonConvert 放在一个临时变量中(就像我所做的那样)并使用调试器查看它.单击沙漏右侧的箭头并选择 Text Visualizer.

A) You are looking at the result from the debugger. To check for this, Put the JsonConvert in a temporary variable (like I did) and look at it with the debugger. Click on the arrow right of the hourglass and select Text Visualizer.

或

B) 调用方法正在将对象再次转换为 Json，因此转义了所有内容.

B) The calling method is transforming the object again to Json, so escaping everything.
