从第一种形式中以第二种形式调用甲基 [英] Call mehtode in 2nd Form from 1st Form

问题描述

我有一个主要形式.它是MDI父级.在这个父母中，我打开第二个表格，然后使用一个类.

看起来像这样:

Hi,

i''ve got a main form. It''s an MDI Parent. In this parent i''m opening a second form and and i''m using a class.

Looks like this:

public partial class Main : Form
    {
     Serial serialPort = new Serial();
[...]
     Util childForm = new Util();
[...]
     childForm.Show();

这很好.我可以启动childForm并在主窗体中使用serialPort.

现在，我想在打开的childForm中使用我的Serial类中的方法.如果没有Main窗体中现有的serialPort，我该怎么办?

this works fine. I can start the childForm and work with the serialPort in my Main form.

Now i want to use the methodes from my Serial class in the opened childForm. How can i do this without the existing serialPort in the Main form?

推荐答案

您显然需要将对Serial类的引用传递给子窗体. :rolleyes:

创建一个重载的构造函数并传递它，或者创建一个属性并设置它.

You''ll need to pass a reference to the Serial class to the child form obviously. :rolleyes:

Create a overloaded constructor and pass it in or create a property and set it.

有可能，您给我一个例子，因为我找不到任何文章.我可以用错误的关键词搜索吗? :doh:

Is it possible, that you give me an example, cuz i can''t find any article. May i search with the wrong keywords. :doh:
