Question

我正在以 JSON.Stringify（$（“ ourForm”）。serializeArray（））发送表单数据（找不到将表单发送到控制器的其他方式）

那么我该如何使用c＃在控制器端逆转此Stringify？

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 \”：\ “ \”}，{\“ name \”：\“ A \”，\“ value \”：\“ \”}，{\“ name \”：\“ B \”，\“ value \”：\ “ \”}，{\“ name \”：\“ C \”，\“ value \”：\“ \”}，{\“ name \”：\“ D \”，\“ value \”：\ “ \”}，{\“ name \”：\“ E \”，\“ value \”：\“ \”}，{\“ name \”：\“ correct_answer \”，\“ value \”：\ “ \”}]“

ViewModel：

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。创建POCO进行反序列化是最容易的（尽管如果需要，使用dynamic类型进行反序列化也很棘手）。

[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
*/
