我在C#中做了一个具有多个组成部分的指南。 每个构成部分有一个纽州。 我要知道,被点击的纽顿中哪一部分来自何处。 我不知道从头开始的构成部分数目,因为如果用户想要的话,允许他们增加更多,因此我可以把这些内容或任何东西引出。 感谢!
What is the use of default keyword in C#? Is it introduced in C# 3.0 ?

假设你们的每个“支持者”都 on到纽克州的活动。
在此情况下,根据你(全心全意)已知的控制树结构,使用“电离层”参数。
void button_Clicked(object sender, EventArgs e)
{
var button = sender as Button;
var ownerControl = button.Parent as MyControl; // But you may need to walk up more levels if need be... Depends on your UI structure.
// Do stuff with button and owner control
}
更糟糕的是,你“串通”的“布布尔”活动,这样它就能够有自己的活动:
public event EventHandler ButtonClicked;
protected virtual void OnButtonClicked()
{
var handler = ButtonClicked;
if (handler != null)
{
handler(this, EventArgs.Empty);
}
}
void button_Clicked(object sender, EventArgs e)
{
OnButtonClicked(); // Bubble the event
}
然后,你的主控(所有“伙伴”)将围绕每个生产项目进行ButtonClicked活动,直接从手稿< ender参数中找到该项目。
我建议设立一个事件。 ButtonClicked on each part, 然后将部件作为object sender
在事件的手稿中使用。
