C#：如何在调用时触发事件的方法上创建属性

csharp
using System;
public class CustomEventArgs : EventArgs
{
    public string Property1 { get; set; }
    public int Property2 { get; set; }
    public CustomEventArgs(string property1, int property2)
    {
        Property1 = property1;
        Property2 = property2;
    }
}
public class Publisher
{
    public event EventHandler EventOccurred;
    public void DoSomething()
    {
        // 在调用事件的方法中创建属性
        CustomEventArgs args = new CustomEventArgs("value1", 2);
        // 调用事件
        EventOccurred?.Invoke(this, args);
    }
}
public class Subscriber
{
    public void HandleEvent(object sender, CustomEventArgs args)
    {
        // 处理事件，并访问属性
        Console.WriteLine($"Property1: {args.Property1}, Property2: {args.Property2}");
    }
}
public class Program
{
    public static void Main(string[] args)
    {
        Publisher publisher = new Publisher();
        Subscriber subscriber = new Subscriber();
        // 订阅事件
        publisher.EventOccurred += subscriber.HandleEvent;
        // 调用事件
        publisher.DoSomething();
    }
}
