C#中实现button按下保持显示1，松开显示0的实现

刚开始接触C#编程，想实现button2保持按下时显示1，松开显示0

Answer 1

private void button1_MouseDown(object sender, MouseEventArgs e)

{

button1.Text = "我是鼠标按下显示1";

}

private void button1_MouseUp(object sender, MouseEventArgs e)

{

button1.Text = "我是松开0";

}

Answer 2

追问

if (按钮被按下)
{
int i ;
i="1";
}
if里面该怎么写呢？
