将自定义事件参数传递给timer_TICK事件

Question

我有课

//Create GroupFieldArgs as an EventArgs
    public class GroupFieldArgs : EventArgs
    {
        private string groupName = string.Empty;
        private int aggregateValue = 0;
        //Get the fieldName
        public string GroupName
        {
            set { groupName = value; }
            get { return groupName; }
        }
        //Get the aggregate value
        public int AggregateValue
        {
            set { aggregateValue = value; }
            get { return aggregateValue; }
        }
    }

我有另一个创建事件处理程序的类

public class Groupby
{
 public event EventHandler eh;
}

最后我在我的表单上有Timer,它有Timer_TICK事件.我想在Timer_TICK事件中传递GroupFieldArgs.最好的方法是什么？

只需将您的arg(s)附加到计时器对象的"Tag"属性中 - 其他任何"可能"都是过度的:

Timer SomeTimer;
void SomeMethod()
{
    SomeTimer = new Timer();
    SomeTimer.Tag = "myArgString"; // or struct, class, list, etc..
    SomeTimer.Tick += new EventHandler(SomeTimer_Tick);
    SomeTimer.Start();
}

void SomeTimer_Tick(object sender, EventArgs e)
{
    string s = ((Timer)sender).Tag; // SomeTimer.Tag
}
