c# - MVP 监督控制器中未触发事件

Question

我为 Presenter 创建了抽象类

public abstract class MvpPresenter<T>
{
    public T View { get; set; }

    public MvpPresenter()
    {
    }

    public MvpPresenter(T view)
    {
        View = view;
    }
}

和继承自抽象 Presenter 的 UserPresenter 类

public class UserPresenter2 : MvpPresenter<IUserView>
{
    private void OnUserSave(object sender, EventArgs e)
    {
        if (View.ContextData.IsDirty)
        {
            User user = new User();

            User domainUser = DataMapper.Translate(View.ContextData);
            new UserServiceStub().SaveUser(domainUser);
        }
    }

    private void OnUserSearch(object sender, SearchEventArgs e)
    {
        if (string.IsNullOrEmpty(e.SearchCriteria))
        {
            View.StatusMessage = "User name can not be null";
            return;
        }

        User user = new UserServiceStub().GetUser(e.SearchCriteria);
        if (user == null)
        {
            View.StatusMessage = String.Format(
                "There's no user found for user name:{0}", e.SearchCriteria);
            return;
        }

        UserDTO userDTO = DataMapper.Translate(user);
        View.ContextData = userDTO;
    }
}

查看代码：

 public abstract class MvpView<TPresenter, TView> : Page
    where TPresenter : MvpPresenter<TView>
{
    public TPresenter Presenter { get; set; }

    public MvpView()
        : base()
    {
        if (!(this is TView))
            throw new Exception("MvpView must implement the interface provider as generic TView type");

        // Create and initialize presenter
        Presenter = Activator.CreateInstance<TPresenter>();
        Presenter.View = (TView)((object)this);
    }
}

问题是当用户点击搜索时，页面没有响应。我知道搜索事件尚未在视图中注册，但我无法在构造函数中执行此操作。
