以前要轉(zhuǎn)json一般都是自己手工去寫(xiě),再不濟(jì)就是用Newtonsoft.Json.dll這個(gè)第三方的類(lèi)庫(kù)
今天突然發(fā)現(xiàn).NET4.0里面自帶了,這可真是一個(gè)偉大的發(fā)現(xiàn)
準(zhǔn)備工作 需要引用 System.Web.Extensions.dll 這個(gè)類(lèi)庫(kù) 命名空間: System.Web.Script.Serialization |

數(shù)據(jù)結(jié)構(gòu) public class Team
{
public string Name { get; set; }
public List<User> Users { get; set; }
}
public class User
{
public int Id { get; set; }
public string Name { get; set; }

Class --> JSON JavaScriptSerializer js = new JavaScriptSerializer();
Team team = new Team()
{
Name = "夢(mèng)之隊(duì)",
Users = new List<User>() {
new User() { Id = 1, Name = "XXX" },
new User() { Id = 2, Name = "YYY" },
new User() { Id = 3, Name = "ZZZ" },
}
};
string json = js.Serialize(team);
Console.WriteLine(json); 輸出結(jié)果
