我正在尝试将标签网格移动到鼠标的位置，就像冒险游戏中的移动一样。理想情况下，我会在途中删除并重绘它们。但是，现在我只想弄清楚如何将 int 转换为厚度或点到屏幕。

到目前为止，我有：

player.XMove =  (int)Mouse.GetPosition(Application.Current.MainWindow).X;
player.YMove = (int)Mouse.GetPosition(Application.Current.MainWindow).Y;

我尝试将 player.XMove 和 player.YMove 转换为厚度并将其存储为带有标签的网格的边距。我在转换时遇到了一些麻烦。那么，有没有人能够提供转换方面的帮助？此外，是否有更好的标签/网格属性将点转换为

编辑：添加了当前代码和 XAML。我还没有机会摆弄它。

这是我当前的代码的样子：

public class User
    {
        private int fed;
        public int Fed
        {
            get
            {
                return fed;
            }
            set
            {
                fed = 5;
            }
        }

        private bool visible;
        public bool Visible
        {
            get
            {
                return visible;
            }
            set
            {
                visible = value;
            }
        }

        private int xMove;
        public int XMove
        {
            get
            {
                return xMove;
            }
            set
            {
                xMove = value;
            }
        }

        private int yMove;
        public int YMove
        {
            get
            {
                return yMove;
            }
            set
            {
                yMove = value;
            }
        }

    }

我最终会在用户类和位置类之间添加Has A或。（未发布。）Uses A

我在主窗口中的代码：

public partial class MainWindow : Window
    {
        User player = new User();
        ThicknessConverter perimeter = new ThicknessConverter();
        public MainWindow()
        {
            InitializeComponent();

        }

        private void Hansel_IsVisibleChanged(object sender, DependencyPropertyChangedEventArgs e)
        {
             Hansel.Visibility = Visibility.Visible;
        }

        private void Hansel_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
        {
            player.XMove =  (int)Mouse.GetPosition(Application.Current.MainWindow).X;
            player.YMove = (int)Mouse.GetPosition(Application.Current.MainWindow).Y;

        }

        private void southRectangle_IsHitTestVisibleChanged(object sender, DependencyPropertyChangedEventArgs e)
        {

        }


    }

我也在努力将布尔值转换为可见性，但遇到了 XAML 无法找到转换器命名空间的错误，该命名空间就在那里。

XAML 看起来像：

如果有一种简单的方法可以以编程方式生成 XAML 对象并将它们分配到理想的初始位置，那么从长远来看，这个项目是理想的，但现在我不太担心这一点。
