推荐答案

此处 [ ^ ]是一篇文章，描述了用于传递数据的不同技术表格之间. :)

Here[^] is an article which describes different techniques for passing data between forms. :)

写道:​​

我想将一些数据从子表单发送到已经打开的父表单

I want to send some data from child form to already opened parent form

您可以使用本文中介绍的对象方法"找到解决此问题的简单方法.此处的示例代码用于将数据从父级传递到子级，但是使用描述的方法将数据从子级传递到父级非常容易.试一试！ :)

You can find simple solution to this problem by using the "Object Approach" described in the article. The sample code there is for passing data from parent to the child, but it is very easy to pass data from child to parent, using the described approach. Give it a try! :)

我认为您可以通过使用子表单的对象轻松访问该子表单的数据

例如
childform.controlid
或
childform.object

i think you can easily access data of the child form by using object of that form

for example
childform.controlid
or
childform.object

在我的头顶上，您可以:

Off the top of my head, you could:

1. 向子表单添加公共属性.
2. 从ShowDialog方法返回数据.
3. 将委托传递给子表单调用的子表单的构造函数. /li>
4. 在子表单上订阅事件.
