Question

我遇到了Picturebox（picWorld）的问题。当我想像这段代码一样改变它的大小和位置时，花了很多时间，因为我认为它正在更新两次：

private void lblWorld_MouseEnter(object sender, EventArgs e)
{
    picWorld.Size = new Size(148, 148);
    picWorld.Location = new Point(picWorld.Location.X - 12, picWorld.Location.Y - 12);
}

有没有办法让它更快？

Answer 1

尝试隐藏它，移动它，然后显示它：

private void lblWorld_MouseEnter(object sender, EventArgs e)
{
    picWorld.Hide();
    picWorld.Size = new Size(148, 148);
    picWorld.Location = new Point(picWorld.Location.X - 12, picWorld.Location.Y - 12);
    picWorld.Show();
}

Answer 2

创建一个外部变量（首选静态）来存储何时开始和何时结束，所以：

bool now=false;

private void lblWorld_MouseEnter(object sender, EventArgs e)
{
if (!now)
{
now = true;
    picWorld.Size = new Size(148, 148);
    picWorld.Location = new Point(picWorld.Location.X - 12,     picWorld.Location.Y - 12);
now = false;
}

}

如何使Picturebox停止自动验证？
