如果继承usercontrole如何从另一个类调用类 [英] if inherits usercontrole how to call class from some another class

问题描述

如果它是由System.Windows.Forms.UserControl继承的，我如何在窗体应用程序中调用另一个类.我知道我们不能通过使用instance.showDilog()方法来调用它，然后如何调用此类CS文件.

推荐答案

您对待所有控件的方式相同.
因此，您可以将其从工具箱拖动到窗体上，或者将其添加到另一个控件的Controls集合中.

You treat it the same way as you treat all controls.
So you either drag it onto a form from your toolbox, or you add it to the Controls collection of another Control.

MyControl myControl = new MyControl
Form1.Controls.Add(myControl)

我认为您对UserControl ...
感到困惑
UserControl不是Form. ShowDialog不能显示它.它是一个控件(如Button或TextBox或其他任何控件)，您可以将其放入Form中.

如果要将控件放在表单中，然后使用ShowDialog显示该表单，则不需要UserControl.只需在项目中添加Form并将控件放入其中即可.

I think you are confused about UserControl...

A UserControl is not a Form. It can''t be displayed with ShowDialog. It is a control (like a Button or TextBox or whatever) which you can put inside a Form.

If you want to put controls inside a form and then display that form using ShowDialog, then you don''t need a UserControl. Just add a Form in your project and put the controls inside it.
