当我有嵌套对象时如何反序列化JSON？

JSON response string send by client:

客户端发送的JSON响应字符串:

{  "{\"user_id\":\"\",\"school_id\":\"1\",\"user_name\":\"pfirstname1@example.com\",\"firstname\":\"pfirstname1\",\"surname\":\"psurname1\",\"type\":\"P\",\"phoneno\":\"1446863\",\"mobileno\":\"3614632\",\"address\":\"mehdipatnam\",\"relation\":\"Father\",\"date_created\":\"\",\"student_dto\":": {    "{\"student_id\":0,\"user_id\":0,\"firstname\":\"sfirstname1\",\"surname\":\"ssurname1\",\"rollno\":1,\"class_id\":\"2\",\"school_id\":\"1\",\"address\":\"mehdipatnam\",\"remarks\":\"\",\"date_created\":\"\"}]}": ""  }}

Then to deserialize this I'm doing this step:

然后反序列化这个我正在做这个步骤:

dynamic data = new JavaScriptSerializer().Deserialize(response.ToString(), typeof(object));

Then when I look in to the debugger I can see:

然后,当我查看调试器时,我可以看到:

[0] {[{"user_dto":{"user_id":"","school_id":"1","user_name":"pfirstname1@example.com","firstname":"pfirstname1","surname":"psurname1","type":"P","phoneno":"1446863","mobileno":"3614632","address":"mehdipatnam","relation":"Father","date_created":"","student_dto":, System.Collections.Generic.Dictionary`2[System.String,System.Object]]}  System.Collections.Generic.KeyValuePair<string,object>

But how do I access the values?

但是我如何访问这些值?

I'm going into this assuming that the mess you posted as JSON should actually be the following after all the \" and erroneous quotes are removed.

假设在删除了所有“错误”引号之后,你发布的JSON信息实际上应该是以下内容。

{
    "user_id":"",
    "school_id":"1",
    "user_name":"pfirstname1@example.com",
    "firstname":"pfirstname1",
    "surname":"psurname1",
    "type":"P",
    "phoneno":"1446863",
    "mobileno":"3614632",
    "address":"mehdipatnam",
    "relation":"Father",
    "date_created":"",
    "student_dto":
    {
        "student_id":0,
        "user_id":0,
        "firstname":"sfirstname1",
        "surname":"ssurname1",
        "rollno":1,
        "class_id":"2",
        "school_id":"1",
        "address":"mehdipatnam",
        "remarks":"",
        "date_created":""
    }
}

If that's the case, then json2csharp.com gives the following as the classes to deserialize into:

如果是这种情况,则json2csharp.com将以下内容作为要反序列化的类:

public class StudentDto
{
    public int student_id { get; set; }
    public int user_id { get; set; }
    public string firstname { get; set; }
    public string surname { get; set; }
    public int rollno { get; set; }
    public string class_id { get; set; }
    public string school_id { get; set; }
    public string address { get; set; }
    public string remarks { get; set; }
    public string date_created { get; set; }
}

public class RootObject
{
    public string user_id { get; set; }
    public string school_id { get; set; }
    public string user_name { get; set; }
    public string firstname { get; set; }
    public string surname { get; set; }
    public string type { get; set; }
    public string phoneno { get; set; }
    public string mobileno { get; set; }
    public string address { get; set; }
    public string relation { get; set; }
    public string date_created { get; set; }
    public StudentDto student_dto { get; set; }
}

Now you should be able to deserialize directly into that type.

现在,您应该能够直接反序列化为该类型。

new JavaScriptSerializer().Deserialize<RootObject>(response.ToString());
