c#中button的坐标问题

怎么样使BUtton按钮在鼠标移至它上面时向下移动离开后回到原来的位置
我的代码是这样的
private void btnKeHuGenJin_MouseLeave(object sender, EventArgs e)
{

int b = Convert.ToInt32(btnKeHuGenJin.Top) +3;
int a = Convert.ToInt32(btnKeHuGenJin.Location.X);
btnKeHuGenJin.Location = new Point(a, b);

//btnKeHuGenJin.Top = b;
//btnKeHuGenJin.Left = a;
}

private void btnKeHuGenJin_MouseMove_1(object sender, MouseEventArgs e)
{
int b = Convert.ToInt32(btnKeHuGenJin.Location.Y) - 3;
int a = Convert.ToInt32(btnKeHuGenJin.Location.X);
btnKeHuGenJin.Location = new Point(a, b);
}

运行后怎么没有恢复到原来的位置

Answer 1

int MoveJL=10;
int OldTop;
private void button1_MouseMove(object sender, MouseEventArgs e)
{
button1.Top = OldTop+MoveJL;
}

private void Form1_Load(object sender, EventArgs e)
{
OldTop = button1.Top;
}

private void button1_MouseLeave(object sender, EventArgs e)
{
button1.Top = OldTop;
}
