X:将ViewModel RelayCommand绑定到DataTemplate中的命令

public class MyViewModel : INotifyPropertyChanged
{
    private RelayCommand _myCommand;
    public ICommand MyCommand
    {
        get
        {
            if (_myCommand == null)
            {
                _myCommand = new RelayCommand(ExecuteMyCommand, CanExecuteMyCommand);
            }
            return _myCommand;
        }
    }

    private void ExecuteMyCommand(object parameter)
    {
        // 命令执行逻辑
    }

    private bool CanExecuteMyCommand(object parameter)
    {
        // 命令是否可执行的逻辑
        return true;
    }

    // INotifyPropertyChanged implementation...
}
