在C#中使事件异步的最佳方法

using System;
using System.Threading.Tasks;

class AsyncEventExample
{
    public delegate void MyEventHandler(object sender, EventArgs args);

    public event MyEventHandler MyEvent;

    public Task<bool> SimulateAsynchronousEventAsync()
    {
        var tcs = new TaskCompletionSource<bool>();

        MyEventHandler handler = (sender, args) =>
        {
            Console.WriteLine("Event triggered asynchronously.");
            tcs.SetResult(true);
        };

        MyEvent += handler;

        // 触发事件
        OnMyEvent(EventArgs.Empty);

        // 移除事件处理程序
        MyEvent -= handler;

        return tcs.Task;
    }

    protected virtual void OnMyEvent(EventArgs args)
    {
        MyEvent?.Invoke(this, args);
    }
}
