c# json轉換實例

用戶實體：

 1 public class UserModel
 2 {
 3     public long? UserId { get; set; }
 4     public string UserName { get; set; }
 5     public string UserPwd { get; set; }
 6     public long? RoleId { get; set; }
 7     public string RoleName { get; set; }
 8     public int UserType { get; set; }
 9     public int UserStatus { get; set; }
10     public DateTime? CreateTime { get; set; }
11     public DateTime? UpdateTime { get; set; }
12     public long? CreateUserId { get; set; }
13     public long? UpdateUserId { get; set; } 
14 }

利用JSON.NET的JsonConvert對象序列化(用戶實體)爲json字符串：

UserModel model =new UserModel();
model.UserId = 0001;
model.UserName = "張三";
model.UserPwd = "nibabadexiaobibi";
model.RoleId = 3;
model.UserType = 2;
model.UserStatus = 1;
model.CreateTime = Datetime.Now;
model.UpdateTime = DateTime.Now;
model.CreateUserId = 88;
model.CreateUserId = 89;

var jsonData = Newtonsoft.Json.JsonConvert.SerializeObject(model);

result:
{
　　\"UserId\":0001,
　　\"UserName\":\"張三\",
　　\"UserPwd\":\"nibabadexiaobibi\",
　　\"RoleId\":3,
　　\"UserType\":2,
　　\"UserStatus\":1,
　　\"CreateTime\":\"2016-08-09 00:00:00\",
　　\"UpdateTime\":\"2016-08-09 00:00:00\",
　　\"CreateUserId\":88,
　　\"UpdateUserId\":89
}

再將json字符串轉換爲實體對象：

UserModel model = Newtonsoft.Json.JsonConvert.DeserializeObject<UserModel>(jsonData);output:model.UserName
