任何类型的system.windows.controls作为函数[C＃]中的参数 [英] Any type of system.windows.controls as a parameter in a function [C#]

问题描述

我正在尝试创建一个将PreviewMouseDown事件分配给任何类型的System.Windows.Controls的函数。但是我应该输入什么作为参数呢？



我尝试了什么：



对于尝试这样的事情感到愚蠢

I'm trying to create a function that assigns a "PreviewMouseDown" event to any type of System.Windows.Controls. But what should I type as a parameter?

What I have tried:

feel silly for trying something like this

public static void dragcontrol(object ctrl)
        {
            ctrl.GetType() test = ctrl as System.Windows.Controls;
        }

推荐答案

它必须是一个来自UIElement的控件，所以不会是每个控件< br $>

It will have to be a control that derives from UIElement, so that's not going to be every control

private void Attach(System.Windows.UIElement uiElement)
{
    uiElement.PreviewMouseDown += UiElement_PreviewMouseDown;
}
