在Visual Basic中,我知道该怎么做,但我是新的C#,所以你们可以告诉我,我该怎么做一个“私人无效”与应用相同的事件,多个控件鼠标悬停? 这里有一个例子:
private void button1, button2, button3, button4_MouseHover(object sender, EventArgs e)
{
btn.Image = pic
}
在Visual Basic中,我知道该怎么做,但我是新的C#,所以你们可以告诉我,我该怎么做一个“私人无效”与应用相同的事件,多个控件鼠标悬停? 这里有一个例子:
private void button1, button2, button3, button4_MouseHover(object sender, EventArgs e)
{
btn.Image = pic
}
只需要声明一个事件处理程序,它指向每个按钮:
private void Common_MouseHover(object sender, EventArgs e)
{
Button btn = sender as Button;
if (btn != null)
btn.Image = pic
}
然后,在代码中或设计师:
button1.MouseHover += Common_MouseHover;
button2.MouseHover += Common_MouseHover;
.. etc
当您订阅按钮上的事件,它只是一个标准的事件处理程序:
button1.Click += myEventHandler;
您可以使用相同的代码来添加处理程序的每个按钮:
button1.Click += myEventHandler;
button2.Click += myEventHandler;
button3.Click += myEventHandler;
button4.Click += myEventHandler;
button5.Click += myEventHandler;
button6.Click += myEventHandler;
button1.MouseOver += OnMouseOver(...)
button2.MouseOver += OnMouseOver(...)
button3.MouseOver += OnMouseOver(...)
button4.MouseOver += OnMouseOver(...)
