如何在winforms mvp模式中实现usercontrol? [英] how Implement usercontrol in winforms mvp pattern?

问题描述

我想实现MVP模式.我有一个带有一些文本框的用户控件，当我将其放入表单时，我从usercontrol调用一个方法并填充文本框.但是在mvp模式下，我不知道如何访问usercontrol1.fill().你有一个可以帮助我的例子吗?

I want to Implement MVP pattern. I have a user control that has some Textboxes and when I put it in form I call a method from usercontrol and fill textboxes. But in mvp pattern I don't know how I can access to usercontrol1.fill(). Do you have an example that could help me?

推荐答案

以下是该模式的示例实现.演示者仅知道具有show方法的界面.演示者将其调用，但是唯一的表单(又称视图")实现了表单的显示方式.

Here is an example implementation of the pattern. The Presenter only knows about the interface having a show method. The Presenter calls it, but the only the form (aka View) implements how the form should be displayed.

public interface IMyFormView {
    void Show();
}

public class MyForm : IMyFormView {

    public MyForm() {
        var presenter = new MyFormPresenter(this);
        presenter.Init();
    }

    public void Show() {
        usercontrol1.fill();
    }
}

public class MyFormPresenter
{
    private IMyView _view;
    public MyFormPresenter(IMyView view) {
        _view = view;
    }

    public void Init() {
        _view.Show();
    }
}

如果需要将数据传递到视图中，则可以通过Show方法传递视图模型或在视图上设置自定义属性.

If you need to pass data into the view, then you can pass a view model through the Show-method or set custom Properties on the view.
