如何将Json字符串转换为c#类对象? [英] How to convert Json string to c# Class object?

问题描述

我已经在Controller中收到json字符串，现在我想将该字符串映射到C#类对象中 我该怎么办?

I have receive json string in Controller, now i want to map that string in to C# class object How can i do that?

JSON:

[{"PdID":null，"StName":"435"，"DOB":"2015-05-02T17:09:35.974Z"，"Gender":"5435"}，{"PdID": null，"StName":"4343"，"DOB":"2015-05-02T17:09:35.974Z"，"Gender":"4345"}]`

[{"PdID":null,"StName":"435","DOB":"2015-05-02T17:09:35.974Z","Gender":"5435"},{"PdID":null,"StName":"4343","DOB":"2015-05-02T17:09:35.974Z","Gender":"4345"}]`

我的课:

public class PersonDetail
{
    public int PdID { get; set; }
    public int PolicyPurchesID { get; set; }
    public string StName { get; set; }
    public DateTime DOB { get; set; }
    public byte Gender { get; set; }
}

现在在我的控制器中，我已经这样做了:-

Now in my controller i have do this:-

public ActionResult PolicyDetailAdd(string jsn)
{
    try
    {               
        JavaScriptSerializer objJavascript = new JavaScriptSerializer();

        PersonDetail testModels = (PersonDetail)objJavascript.DeserializeObject(jsn);

        return null;
     }
}

我在这方面有例外:

无法转换类型为System.Object []的对象来键入WebApplication1.Models.PersonDetail.

Unable to cast object of type System.Object[] to type WebApplication1.Models.PersonDetail.

如何将这个字符串放入列表对象?

How can I get this string into list object?

推荐答案

发生此错误是因为您试图将一个集合反序列化为一个对象.另外，您正在使用通用Object.您将需要使用

The error occurs because you are trying to deserialize a collection to an object. Also you are using the generic Object. You will need to use

List<PersonDetail> personDetails = objJavascript.Deserialize<List<PersonDetail>>(jsn);
