反序列化JSON作爲一個泛型列表

Question

我有一個過濾字符串如在下面的格式：

{"groupOp":"AND","rules":[{"field":"FName","op":"bw","data":"te"}]} 

我需要反序列化這個作爲項目的泛型列表。

任何人都可以指導我如何做到這一點？

Answer 1

嘗試使用JavaScriptSerializer類，如下所示：

反序列化碼

using System.Web.Script.Serialization; 

... 

string json = "{\"groupOp\":\"AND\",\"rules\":[{\"field\":\"FName\",\"op\":\"bw\",\"data\":\"te\"}]}"; 
JavaScriptSerializer serializer = new JavaScriptSerializer(); 
Filter filter = (Filter)serializer.Deserialize<Filter>(json); 

類

public class Filter 
{ 
    public string GroupOp { get; set; } 
    public List<Rule> Rules { get; set; } 

    public Filter() 
    { 
     Rules = new List<Rule>(); 
    } 
} 

public class Rule 
{ 
    public string Field { get; set; } 
    public string Op { get; set; } 
    public string Data { get; set; } 
} 

Answer 2

看看JSON.NET。它允許你做這樣的事情：

JObject o = new JObject(
    new JProperty("Name", "John Smith"), 
    new JProperty("BirthDate", new DateTime(1983, 3, 20)) 
); 

JsonSerializer serializer = new JsonSerializer(); 
Person p = (Person)serializer.Deserialize(new JTokenReader(o), typeof(Person)); 

Console.WriteLine(p.Name); 
// John Smith
