c#委托调用过程

第一步、modbus管理类开启委托

public class ModbusRtuMgr
{
    static ModbusRtuMgr _inst;
    ModbusRtuClient _rtuClient;
    public bool active;

    //开启委托回调
    public Action<DataRequestOne> onGetRequestOne;

//单例模式

 public static ModbusRtuMgr It
 {
     get
     {
         if (_inst == null)
             _inst = new ModbusRtuMgr();
         return _inst;
     }
 }

第二步、在readweigh 里定义委托的数据结构

public void ReadWeigh(string address)
{

    float weigh = _rtuClient.ReadAddress(address);

    //模拟通道称重数据
    float[] weighList = _rtuClient.ReadAddresses(address);

    for (int i = 0; i < weighList.Length; i++)
    {
        DataRequestOne one = new DataRequestOne();
        one.ttime = 1;
        one.pass = i+1;
        one.weigh = weighList[i];
        one.standWeigh = 90;
        one.kickMin = 89;
        one.kickMax = 101;

        float per = Math.Abs(weigh - one.standWeigh) / one.standWeigh;
        one.ngStatus = per < 0.05f ? 0 : 1;

        bool kickFlag = (one.kickMin < weigh && weigh < one.kickMax);
        one.kickStatus = kickFlag ? 0 : 1;

        onGetRequestOne?.Invoke(one);

    }

}

main class

第三步  、//开启线程循环读取 weight数组   启动那个方法
    Task.Run(() =>
{

    int count = 0;
    //循环读取， 1秒一次
    while (true)
    {
        ModbusRtuMgr.It.ReadWeigh("0");

        Thread.Sleep(1000);
    }

})

第四步 、定义数据处理方法    //预设给委托处理方法
    private void HandleWeighData(DataRequestOne data)
    {
        int count = 0;
        Console.WriteLine($"重量 {data.weigh}");
    }

 // 委托回调数据传到给这个方法  用等于号代表这个方法阻塞其他方法调用
 ModbusRtuMgr.It.onGetRequestOne = HandleWeighData;
