推荐答案

一种方法-捕获代码中的所有事件.然后，调用使用sender作为参数的通用方法.更改发件人的背景色.

像-

One approach - capture all the events in your code. Then, call a common method which uses the sender as the parameter. Change the back color of the sender.

Something like -

void textBox1_GotFocus(object sender, System.EventArgs e)
{
    CommonColorChangerMethod(sender);
}
void CommonColorChangerMethod(object sender)
{
    ((TextBox)sender).BackColor = ....
}
