Question

Trying to create a simple noddy example so that I can build my next project using fluent interfaces. I need to provide the user of my dll with an intuitive step by step way of building a class.

Question. I would like the user only to see Initialise when the first start then step1 then step2 and then end?How can I do it?

这是我的尝试一旦你把"。" 你看到一切,然后他们隐藏。

class Program
{
    static void Main(string[] args)
    {
        IEnd builder = new StepBuilder()
            .Initialize()
            .LoadStuff()
            .Validate()
            .End();

                              IStep3,
                              IEnd

关于逐步建立流利界面的建议或良好联系?

Answer 1

您可以将 Intialize () 转换为静态工厂方法, 并让构建器成为私有。然后您的创建代码将看起来像 :

    IEnd builder = StepBuilder.Initialize()
         .LoadStuff()
         .Validate()
         .End();

第二个想法是让接口执行清晰化。然后您只看到您当时正在处理的接口的方法。

s 两种方法的示例代码。接口与您的问题完全相同。

工厂方法实例:

class Program
{
    static void Main(string[] args)
    {
        IEnd builder = StepBuilder
            .Initialize()
            .LoadStuff()
            .Validate()
            .End();

    }
}

public class StepBuilder : IInitialize,
                             IStep1,
                             IStep2,
                             IStep3,
                             IEnd
{
    private StepBuilder()
    {
    }

    public static IStep1 Initialize()
    {
        var builder = new StepBuilder();
        //do initialisation stuff
        return builder;
    }

    public IStep2 LoadStuff()
    {
        return this; 
    }

    public IStep3 Validate()
    {
        return this;
    }

    public IEnd End()
    {
        return this;
    }

    public bool Save()
    {
        return true;
    }
}

具有明确接口执行的示例:

class Program
{
    static void Main(string[] args)
    {
        IEnd builder = new StepBuilder()
            .Initialize()
            .LoadStuff()
            .Validate()
            .End();

    }
}

public class StepBuilder : IInitialize,
                             IStep1,
                             IStep2,
                             IStep3,
                             IEnd
{
    public IStep1 Initialize()
    {
        return this;
    }

    public IStep2 IStep1.LoadStuff()
    {
        return this; 
    }

    public IStep3 IStep2.Validate()
    {
        return this;
    }

    public IEnd IStep3.End()
    {
        return this;
    }

    public bool IEnd.Save()
    {
        return true;
    }
}
