                }
            }
        }

推荐答案

以下代码可能会有所帮助。

The below code might help.

button1.MouseEnter += new MouseEventHandler(button1_MouseEnter);
button1.MouseLeave += new MouseEventHandler(button1_MouseLeave);

void button1_MouseEnter(object sender, MouseEventArgs e)
{
    button1.Content = image1;
    //do something
}

void button1_MouseLeave(object sender, MouseEventArgs e)
{
    //do something
}
