MV-VM - 在ViewModel中使用命令的任何示例？

public interface ICommand
{
    void Execute();
}

public class MyCommand : ICommand
{
    private readonly Action _action;

    public MyCommand(Action action)
    {
        _action = action;
    }

    public void Execute()
    {
        _action();
    }
}

public class MyViewModel
{
    public ICommand MyCommand { get; }

    public MyViewModel()
    {
        MyCommand = new MyCommand(() =>
        {
            // 在这里执行业务逻辑
        });
    }
}
