示例：

            Dictionary<string, object> parent = new Dictionary<string, object>();
            parent["name"] = "张三";
            parent["age"] = "35";
            Dictionary<string, object> children = new Dictionary<string, object>();
            children["name"] = "张三儿";
            children["age"] = "7";
            parent["children"] = children;

            // 对象序列化成字符串
            string s = DataUtil.SerializeToBase64(parent);
            Console.WriteLine("序列化后结果: " + s);

            // 字符串反序列化成对象
            Dictionary<string, object> d = new Dictionary<string, object>();
            d = DataUtil.DesrializeFromBase64(d, s);
            Dictionary<string, object> cdr = (Dictionary<string, object>)d["children"];
            object childName = cdr["name"];
            Console.WriteLine("反序列化后取值: " + childName);

控制台打印结果：

c# json serialize and deserialize using json.net JsonConvert

Guide

Json.NET

• JsonConvert.SerializeObject
• JsonConvert.DeserializeObject

install

Use NuGet to download the package

"Project" -> "Manage NuGet packages" -> "Search for "newtonsoft json". -> click "install".

code

reference

using Newtonsoft.Json;

serialize collections

Product p1 = new Product
{
    Name = "Product 1",
    Price = 99.95m,
    ExpiryDate = new DateTime(2000, 12, 29, 0, 0, 0, DateTimeKind.Utc),
};
Product p2 = new Product
{
    Name = "Product 2",
    Price = 12.50m,
    ExpiryDate = new DateTime(2009, 7, 31, 0, 0, 0, DateTimeKind.Utc),
};

List<Product> products = new List<Product>();
products.Add(p1);
products.Add(p2);

string json = JsonConvert.SerializeObject(products, Formatting.Indented);
//[
//  {
//    "Name": "Product 1",
//    "ExpiryDate": "2000-12-29T00:00:00Z",
//    "Price": 99.95,
//    "Sizes": null
//  },
//  {
//    "Name": "Product 2",
//    "ExpiryDate": "2009-07-31T00:00:00Z",
//    "Price": 12.50,
//    "Sizes": null
//  }
//]

deserialize collections

string json = @"[
  {
    'Name': 'Product 1',
    'ExpiryDate': '2000-12-29T00:00Z',
    'Price': 99.95,
    'Sizes': null
  },
  {
    'Name': 'Product 2',
    'ExpiryDate': '2009-07-31T00:00Z',
    'Price': 12.50,
    'Sizes': null
  }
]";

List<Product> products = JsonConvert.DeserializeObject<List<Product>>(json);

Console.WriteLine(products.Count);
// 2

Product p1 = products[0];

Console.WriteLine(p1.Name);
// Product 1

serialize to json file

public class Movie
{
    public string Name { get; set; }
    public int Year { get; set; }
}


Movie movie = new Movie
{
    Name = "Bad Boys",
    Year = 1995
};

// serialize JSON to a string and then write string to a file
File.WriteAllText(@"c:movie.json", JsonConvert.SerializeObject(movie));

// serialize JSON directly to a file
using (StreamWriter file = File.CreateText(@"c:movie.json"))
{
    JsonSerializer serializer = new JsonSerializer();
    serializer.Serialize(file, movie);
}
