我有以下课程

public abstract class BaseViewPresenter { }
public abstract class BaseView<T> : UserControl
    where T : BaseViewPresenter { }

public class LoginPresenter : BaseViewPresenter { }
public partial class LoginView : BaseView<LoginPresenter> {  }

我有一个看起来像这样的方法(简化)

public BaseView<BaseViewPresenter> Resolve(BaseViewPresenter model)
{
    var type = model.GetType();
    var viewType = _dataTemplates[type];

    var control = Activator.CreateInstance(viewType);

    // Fails to cast as BaseView<BaseViewPresenter> so returns null
    return control as BaseView<BaseViewPresenter>;
}

当我使用LoginPresenter的实例调用它时

var login = new LoginPresenter();
var ctl = …
