一直在用第三方的Json工具，现在才发现Json.net原版的就很好用。
并且借助JSON转C#实体类工具，几分钟就可以完成解析代码。
比如目前正在做的一个通讯测试，接收的信息如下：
{
"Content": {
"__startTime": "2022-05-14 16:46:46",
"__name": "slave1",
"__description": "安装在泵车2；研华4117模块",
"__config": "[ModbusRtu] [ModRtu/slave1] [Com3:9600-8-N-1]",
"__success": 35865,
"__failed": 0,
"__activeTime": "2022-05-14 20:45:55",
"__captureSpendTime": 372,
"__deviceStatus": true,
"__requestEnable": true,
"__onlineTime": "2022-05-14 16:46:48",
"__failedMsg": "",
"__alarmCount": {
"AlarmCount": 0,
"Hint": 0,
"Warn": 0,
"Error": 0,
"Fatal": 0
},
"三参仪压力": 2222,
"三参仪流量_mA信号": 28493
},
"IsSuccess": true,
"Message": "成功",
"ErrorCode": 0
}直接根据JSon转实体类如下
public class __alarmCount
{
/// <summary>
///
/// </summary>
public int AlarmCount { get; set; }
/// <summary>
///
/// </summary>
public int Hint { get; set; }
/// <summary>
///
/// </summary>
public int Warn { get; set; }
/// <summary>
///
/// </summary>
public int Error { get; set; }
/// <summary>
///
/// </summary>
public int Fatal { get; set; }
}
public class ContentBase
{
/// <summary>
///
/// </summary>
public string __startTime { get; set; }
/// <summary>
///
/// </summary>
public string __name { get; set; }
/// <summary>
/// 安装在泵车2；研华4117模块
/// </summary>
public string __description { get; set; }
/// <summary>
///
/// </summary>
public string __config { get; set; }
/// <summary>
///
/// </summary>
public int __success { get; set; }
/// <summary>
///
/// </summary>
public int __failed { get; set; }
/// <summary>
///
/// </summary>
public string __activeTime { get; set; }
/// <summary>
///
/// </summary>
public int __captureSpendTime { get; set; }
/// <summary>
///
/// </summary>
public string __deviceStatus { get; set; }
/// <summary>
///
/// </summary>
public string __requestEnable { get; set; }
/// <summary>
///
/// </summary>
public string __onlineTime { get; set; }
/// <summary>
///
/// </summary>
public string __failedMsg { get; set; }
/// <summary>
///
/// </summary>
public __alarmCount __alarmCount { get; set; }
}
public class Content : ContentBase
{
/// <summary>
///
/// </summary>
public int 三参仪压力 { get; set; }
/// <summary>
///
/// </summary>
public int 三参仪流量_mA信号 { get; set; }
public int 三参仪流量 { get; set; }
/// <summary>
///
/// </summary>
public int 三参仪密度 { get; set; }
}
public class Root
{
/// <summary>
///
/// </summary>
public Content Content { get; set; }
/// <summary>
///
/// </summary>
public string IsSuccess { get; set; }
/// <summary>
/// 成功
/// </summary>
public string Message { get; set; }
/// <summary>
///
/// </summary>
public int ErrorCode { get; set; }
}
运行结果如下：
总结：Json.NET已经实现了属性自动映射，很强大很好用。
以前的解析方法就不贴上来了，想想都觉得有点脱了裤子放屁。。。。。
官方例子。
反序列化对象 (newtonsoft.com)
This sample deserializes JSON to an object.
Types
Copy
public class Account
{
public string Email { get; set; }
public bool Active { get; set; }
public DateTime CreatedDate { get; set; }
public IList<string> Roles { get; set; }
}Usage
Copy
string json = @"{
'Email': 'james@example.com',
'Active': true,
'CreatedDate': '2013-01-20T00:00:00Z',
'Roles': [
'User',
'Admin'
]
}";Account account = JsonConvert.DeserializeObject<Account>(json);
Console.WriteLine(account.Email);
