将任何按下的键绑定到VM WPF中的命令

public class MyCommand : ICommand
{
    public event EventHandler CanExecuteChanged;

    public bool CanExecute(object parameter)
    {
        // 在此处添加逻辑以确定命令是否可执行
        return true;
    }

    public void Execute(object parameter)
    {
        // 在此处添加按键操作的逻辑
    }
}

public class MyViewModel
{
    public ICommand KeyCommand { get; set; }

    public MyViewModel()
    {
        KeyCommand = new MyCommand();
    }
}
