如何使用 C# 从控制器反转 JSON.Stringify

Question

我将表单数据作为 JSON.Stringify($("ourForm").serializeArray()) 发送（我找不到任何其他方式将表单发送到控制器）

那么如何在 Controller 端使用 c# 反转这个 Stringify 呢？

字符串是这样的（视图中有2个问题模块）：

"[{\"name\":\"question_string\",\"value\":\"\"},{\"name\":\"A\",\"value\":\ "\"},{\"name\":\"B\",\"value\":\"\"},{\"name\":\"C\",\"value\":\ "\"},{\"name\":\"D\",\"value\":\"\"},{\"name\":\"E\",\"value\":\ "\"},{\"name\":\"correct_answer\",\"value\":\"\"},{\"name\":\"question_string\",\"value\":\ "\"},{\"名称\":\"A\",\"值\":\"\"},{\"名称\":\"B\",\"值\":\ "\"},{\"name\":\"C\",\"value\":\"\"},{\"name\":\"D\",\"value\":\ "\"},{\"name\":\"E\",\"value\":\"\"},{\"name\":\"correct_answer\",\"value\":\ "\"}]"

视图模型：

public class Questions
{        
    [Display(Name ="QUESTION HERE")]
    public string question_string { get; set; }
    public string A { get; set; }
    public string B { get; set; }
    public string C { get; set; }
    public string D { get; set; }
    public string E { get; set; }
    [Display(Name ="CORRECT ANSWER")]
    public string correct_answer { get; set; }
}

这可以通过Newtonsoft.Json 来实现。最简单的方法是创建一个 POCO 来反序列化（尽管如果需要，使用 dynamic 类型反序列化可能会变得很棘手）。

[Example Here]

using System;
using System.Collections.Generic;
using Newtonsoft.Json;

// Create model we can deserialize to
public class FormData
{
    public string Name { get; set; }
    public string Value { get; set; }

    public FormData(string name, string val)
    {
        Name = name;
        Value = val;
    }
}

public class Program
{
    public static void Main()
    {
        var formData = "[{\"name\":\"question_string\",\"value\":\"\"},{\"name\":\"A\",\"value\":\"\"},{\"name\":\"B\",\"value\":\"\"},{\"name\":\"C\",\"value\":\"\"},{\"name\":\"D\",\"value\":\"\"},{\"name\":\"E\",\"value\":\"\"},{\"name\":\"correct_answer\",\"value\":\"\"},{\"name\":\"question_string\",\"value\":\"\"},{\"name\":\"A\",\"value\":\"\"},{\"name\":\"B\",\"value\":\"\"},{\"name\":\"C\",\"value\":\"\"},{\"name\":\"D\",\"value\":\"\"},{\"name\":\"E\",\"value\":\"\"},{\"name\":\"correct_answer\",\"value\":\"\"}]";

        var results = JsonConvert.DeserializeObject<List<FormData>>(formData);

        foreach (var datas in results)
        {
            Console.WriteLine(datas.Name);
        }
    }
}

/* OUTPUT:
question_string
A
B
C
D
E
correct_answer
question_string
A
B
C
D
E
correct_answer
*/
