使用TimerCallback时在静态类中使用“全局”变量的替代方法

state 传递给它的参数。

public class Properties
{
    public decimal PercentOfChocolateIceCream { get; set; }  = 0
    public decimal PercentOfRedCars { get; set; } = 0
}

var properties = new Properties();
var timerCallback = new TimerCallback(_outputDisplayer.SetupThreading);
var stateTimer = new Timer(timerCallback, properties, 0, 5000);



void SetupThreading(object? state)
{
    var properties = (Properties)state;

    //etc...
