visual studio使用技巧：快速生成Json、XML对应类

visual studio快速生成Json、XML对应类

在项目中经常用到json或者xml作为配置文件，进行序列化和反序列化就需要有对应的类，重新写一遍类就比较麻烦，这里就讲一下通过visual studio快速生成json或者xml对应类型的方法。

自动生成Json类

复制一个json文件，自动在visual studio中生成

复制Json文件

{
  "DeviceLinks": [
    {
      "UID": "device01",
      "Ip": "127.0.0.1",
      "Port": 502,
      "SlaveId": 1,
      "AcqTimeSpan": 1
    },
    {
      "UID": "device02",
      "Ip": "127.0.0.1",
      "Port": 503,
      "SlaveId": 1,
      "AcqTimeSpan": 1
    }
  ],
  "MqttConfig": {
    "Ip": "127.0.0.1",
    "Port": 1883,
    "Username": "admin",
    "Password": "12345"
  },
  "ServiceConfig": {
    "PushTimeSpan": 5,
    "IsPushScheduled": true,
    "IsPushChanged": true
  }
}

切换到一个cs的类文件

必须在c#的cs文件中，才能看到编辑中对应的菜单

选择性粘贴

在菜单栏，“编辑”→“选择性粘贴”→将JSON粘贴为类

代码自动生成，会生成一个Rootobject为json的主类，子类也会一起生成，这里根据json字段定义，自动生成对应的子类

public class Rootobject
{
    public Devicelink[] DeviceLinks { get; set; }
    public Mqttconfig MqttConfig { get; set; }
    public Serviceconfig ServiceConfig { get; set; }
}

public class Mqttconfig
{
    public string Ip { get; set; }
    public int Port { get; set; }
    public string Username { get; set; }
    public string Password { get; set; }
}

public class Serviceconfig
{
    public int PushTimeSpan { get; set; }
    public bool IsPushScheduled { get; set; }
    public bool IsPushChanged { get; set; }
}

public class Devicelink
{
    public string UID { get; set; }
    public string Ip { get; set; }
    public int Port { get; set; }
    public int SlaveId { get; set; }
    public int AcqTimeSpan { get; set; }
}

自动生成XML类

步骤一样，选择性粘贴中选择“将XML粘贴为类”

示例XML：

<Configuration>
  <DeviceLinks>
    <DeviceLink>
      <UID>device01</UID>
      <Ip>127.0.0.1</Ip>
      <Port>502</Port>
      <SlaveId>1</SlaveId>
      <AcqTimeSpan>1</AcqTimeSpan>
    </DeviceLink>
    <DeviceLink>
      <UID>device02</UID>
      <Ip>127.0.0.1</Ip>
      <Port>503</Port>
      <SlaveId>1</SlaveId>
      <AcqTimeSpan>1</AcqTimeSpan>
    </DeviceLink>
  </DeviceLinks>
  
  <MqttConfig>
    <Ip>127.0.0.1</Ip>
    <Port>1883</Port>
    <Username>admin</Username>
    <Password>12345</Password>
  </MqttConfig>
  
  <ServiceConfig>
    <PushTimeSpan>5</PushTimeSpan>
    <IsPushScheduled>true</IsPushScheduled>
    <IsPushChanged>true</IsPushChanged>
  </ServiceConfig>
</Configuration>
