在这种情况下,我需要一个带有抽象工厂的工厂吗?

您希望根据类型的不同状态显示页面。因此,您的内部页面调用将根据您的上下文进行更改。所以,我建议你用 .

根据我对您的问题陈述的理解,以下代码以C语言实现:

public interface ISomeOperation
{
    string DisplayPage(int status);
}

public class Type : ISomeOperation
{
    public string DisplayPage(int status)
    {
        if (status == 1)
            return "1";
        return string.Empty;
    }
}

public class TypeA : ISomeOperation
{
    public string DisplayPage(int status)
    {
        if (status == 2)
            return "2A";
        if (status == 3)
            return "3A";
        if (status == 4)
            return "4A";
        return string.Empty;
    }
}

 public class TypeB: ISomeOperation
{
    public string DisplayPage(int status)
    {
        if (status == 2)
            return "2B";
        if (status == 3)
            return "3B";
        if (status == 4)
            return "4B";
        return string.Empty;
    }
}

public class TypeC : ISomeOperation
{
    public string DisplayPage(int status)
    {
        if (status == 2)
            return "2C";
        if (status == 3)
            return "3C";
        if (status == 4)
            return "4C";
        return string.Empty;
    }
}

 public class OperationContext
{
    private readonly ISomeOperation _iSomeOperation;

    public OperationContext(ISomeOperation someOperation)
    {
        _iSomeOperation = someOperation;
    }

    public string DisplayPageResult(int status)
    {
        return _iSomeOperation.DisplayPage(status);
    }
}

驾驶员代码:

 class Program
{
    static void Main(string[] args)
    {
        var operationContext = new OperationContext(new Type());
        operationContext.DisplayPageResult(1);

         operationContext = new OperationContext(new TypeB());
        operationContext.DisplayPageResult(2);
        operationContext.DisplayPageResult(3);
        operationContext.DisplayPageResult(4);

        operationContext = new OperationContext(new TypeC());
        operationContext.DisplayPageResult(2);
        operationContext.DisplayPageResult(3);
        operationContext.DisplayPageResult(4);
    }
}

您的问题陈述要求似乎是 页 因此 策略 可能不太适合(关于没有状态变化的算法家族)。如果页面类型是有限的, 静态工厂 或 原型 (如果您需要克隆每个页面实例)将更适合(有两个选择键)。
