如何为ASP.Net自定义控件提供新的自定义事件

public delegate void CustomEventHandler(object sender, CustomEventArgs e);

public class CustomEventArgs : EventArgs
{
    // 在这里添加自定义属性
}

public event CustomEventHandler CustomEvent;

protected virtual void OnCustomEvent(CustomEventArgs e)
{
    CustomEvent?.Invoke(this, e);
}

OnCustomEvent(new CustomEventArgs());

protected void CustomControl_CustomEvent(object sender, CustomEventArgs e)
{
    // 在这里处理自定义事件
}

protected void Page_Load(object sender, EventArgs e)
{
    CustomControl.CustomEvent += CustomControl_CustomEvent;
}
