MDI问题请帮忙 [英] MDI Problem please help

问题描述

您好，我正在c#gui中创建一个小型MDI项目，我的问题是，每当我单击学生菜单条时，都会创建一个新的学生表格实例，每次这样做时，都会创建一个新的学生表格实例他们的任何方法都将首先关闭父窗体中所有已激活的MDI，然后打开学生窗体，
我正在使用在学生菜单栏上编写的以下代码在运行时创建学生表单的实例

studform.MdiParent = this;
studform.Show();

推荐答案

radix3写道:

是它们的any方法，该方法将首先关闭所有父格式的激活的MDI

is their any method which will first close all the activated MDI in the parent form

不-您必须自己编写-看起来像这样:

No - you have to write it yourself - but it will look like this:

foreach (Form f in MdiChildren)
   {
   f.Close();
   }

然后执行您现有的代码，您就在这里.

Then do your existing code, and you are there.
