我希望在 Visual Studio C# 中创建一个模仿 Android 模式锁定屏幕的应用程序，并且想知道是否有人对此有任何提示。
这不是商业项目，不会赚钱，只是有点乐趣。
我一直在 WPF 项目中玩耍，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，但我不认为这是最好的解决方案。
有什么想法吗？

看看这是否可以帮助您是粗略的代码。
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;
}
}
}
}

使用它是添加对话框和按钮来匹配它
if (string.Concat(patternLock1.buttons).ToString() == "1359")
{
this.Close();
}
else
{
patternLock1.ResetPattern();
}
