如何在C#/WPF中检测MouseEnter事件的边界以调整网格元素的大小

private void Grid_MouseEnter(object sender, MouseEventArgs e)
{
    // 获取网格元素
    Grid grid = sender as Grid;

    // 获取鼠标相对于网格元素的位置
    Point mousePosition = e.GetPosition(grid);

    // 获取网格元素的宽度和高度
    double gridWidth = grid.ActualWidth;
    double gridHeight = grid.ActualHeight;

    // 定义边界值，用于调整网格元素的大小
    double border = 10;

    // 如果鼠标进入网格元素的左边界或右边界
    if (mousePosition.X <= border || mousePosition.X >= gridWidth - border)
    {
        // 调整网格元素的宽度
        if (mousePosition.X <= border)
        {
            grid.Width -= border;
        }
        else
        {
            grid.Width += border;
        }
    }

    // 如果鼠标进入网格元素的上边界或下边界
    if (mousePosition.Y <= border || mousePosition.Y >= gridHeight - border)
    {
        // 调整网格元素的高度
        if (mousePosition.Y <= border)
        {
            grid.Height -= border;
        }
        else
        {
            grid.Height += border;
        }
    }
}
