[英]C# JSON deserializing to Custom Class
I would like to deserialize a JSON object like this: 我想反序列化这样的JSON对象:
[{"Response":"OK","UUID":"89172"},{"Response":"OK","UUID":"10304"}]
into a custom class where it has variables storing Response
and UUID
. 到一个自定义类中,该类具有用于存储
Response
和UUID
变量。 However I would want to deserialize multiple data response such as above example. 但是,我想反序列化多个数据响应,例如上面的示例。 It will be great if I can use the method
ForEach
such that I can pop the data out accordingly. 如果我可以使用方法
ForEach
以便可以相应地弹出数据,那就太好了。 Can anyone advise? 有人可以建议吗? Many Thanks!
非常感谢!
write this class 写这个课
public class MyClass
{
public string Response { get; set; }
public string UUID { get; set; }
}
then you can deserialize it using the library newtonsoft.json 然后您可以使用库newtonsoft.json对它进行反序列化
string jsonString = "[{"Response":"OK","UUID":"89172"},{"Response":"OK","UUID":"10304"}]";
...
...
var myListOfItems= JsonConvert.DeserializeObject<List<MyClass>>(jsonString);
foreach(var item in myListOfItems)
{
....
}
FULL CODE IN CONSOLE APPLICATION 控制台应用程序中的完整代码
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Newtonsoft.Json;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
string jsonString = "[{'Response':'OK','UUID':'89172'},{'Response':'OK','UUID':'10304'}]";
var items= JsonConvert.DeserializeObject<List<MyClass>>(jsonString);
foreach (var item in items)
{
Console.WriteLine("UUUID: "+item.UUID);
Console.WriteLine("Response: " + item.Response);
Console.WriteLine();
}
Console.ReadKey();
}
}
public class MyClass
{
public string Response { get; set; }
public string UUID { get; set; }
}
}
I would use Json.Net for that. 我会使用Json.Net。 Have a look at Json.Net help in the "Serializing and Deserializing JSON" section.
在“ JSON序列化和反序列化”部分中查看Json.Net帮助 。
There they show you how to deserialize the json-string into an object. 在那里,他们向您展示了如何将json-string反序列化为一个对象。
You will need Newtonsoft.Json library for this to work: 您将需要Newtonsoft.Json库来使其工作:
public class A
{
public string Response { get; set; }
public string UUID { get; set; }
}
static void Main(string[] args)
{
var json = "[{\"Response\":\"OK\",\"UUID\":\"89172\"}, \"Response\":\"OK\",\"UUID\":\"10304\"}]";
var result = JsonConvert.DeserializeObject<IEnumerable<A>>(json);
foreach (var a in result)
Console.WriteLine("Response: {0} UUID: {1}", a.Response, a.UUID);
Console.ReadKey();
}
I've finally resolved this problem thanks with the help of @Newton Sheikh. 感谢@Newton Sheikh的帮助,我终于解决了这个问题。 Thank you first of all.
首先谢谢你。
First I created a class ( Student
) 首先,我创建了一个班级(
Student
)
public class Student
{
public string Response { get; set; }
public string UUID { get; set; }
}
Then I imported the JSON.NET and created a function: 然后,我导入了JSON.NET并创建了一个函数:
public List<Student> ReturnAllStudentsList()
{
string jsonString = "[{'Response':'OK','UUID':'89172'},{'Response':'OK','UUID':'10304'}]";
List<Student> Students = new List<Student>(); //Creates a list of custom Type: Student
var result = JsonConvert.DeserializeObject<List<Student>>(jsonString);
foreach (var student in result)
{
Students.Add(student);
}
return Students;
}
From this point, I have a list of Students. 至此,我有了学生名单。 Then in my main program, I call this function:
然后在我的主程序中,调用此函数:
private void button1_Click(object sender, EventArgs e)
{
List<Student> Students = ReturnAllStudentsList(); // Gets the list from JSON.
foreach(Student student in Students)
{
// Here I can access to each student for every loop cycle.
MessageBox.Show(student.Response);
}
}
Thank you @Newton Sheikh and others help! 谢谢@Newton Sheikh和其他人的帮助! I hope this example code can help others too!
我希望这个示例代码也可以帮助其他人! Cheers.
干杯。
