c# - Android 锁屏 C# .NET 副本

Question

我想在 Visual Studio C# 中创建一个模拟 Android 模式锁定屏幕的应用程序，想知道是否有人有这样做的任何提示。

这不是一个商业项目，不会赚钱，只是有点乐趣。

我一直在玩 WPF 项目，现在不知所措。我想到的唯一方法是在 MouseDown 事件上跟踪鼠标，并使用 C# 中的绘制功能来“绘制”鼠标所在的位置，但我不觉得这是最好的解决方案。

有什么想法吗？

看看这是否对您有帮助是粗略的代码。

public partial class PatternLock : UserControl
    {
        bool isMouseDown = false;

        private ObservableCollection<ToggleButton> selectedobject = new ObservableCollection<ToggleButton>();
        public PatternLock()
        {
            InitializeComponent();

        }

        internal ObservableCollection<int> buttons = new ObservableCollection<int>();

        private void layoutroot_Checked(object sender, RoutedEventArgs e)
        {
            if (e.OriginalSource is ToggleButton)
                buttons.Add(Convert.ToInt32(((ToggleButton)e.OriginalSource).Content));
        }

        private void layoutroot_Unchecked(object sender, RoutedEventArgs e)
        {
            if (e.OriginalSource is ToggleButton)
            {
                int i = Convert.ToInt32(((ToggleButton)e.OriginalSource).Content);
                buttons.Remove(i);

            }
        }

        internal void ResetPattern()
        {
            if (buttons != null)
            {
                buttons.Clear();
                foreach (ToggleButton item in layoutroot.Children)
                {
                    item.IsChecked = false;
                }
            }

        }
    }

使用这个是添加对话框和按钮来匹配这个作为

   if (string.Concat(patternLock1.buttons).ToString() == "1359")
           {
               this.Close();
           }
           else
           {
               patternLock1.ResetPattern();
           }
