获取在WPF中执行ICommand的状态，以便更新xaml上的文本

public class MyCommand : ICommand
{
    public event EventHandler CanExecuteChanged;

    public bool CanExecute(object parameter)
    {
        // 根据条件返回命令是否可执行的布尔值
        return true; // 这里可以根据实际情况返回true或false
    }

    public void Execute(object parameter)
    {
        // 执行命令时的逻辑
    }
}

public class MyViewModel : INotifyPropertyChanged
{
    private MyCommand _myCommand;

    public MyCommand MyCommand
    {
        get { return _myCommand; }
        set
        {
            _myCommand = value;
            OnPropertyChanged(nameof(MyCommand));
        }
    }

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

    // INotifyPropertyChanged接口实现代码...
}
