你好朋友，

设置您的表单属性ISMDIContainer = true

Hi friend,

Set ur Form property ISMDIContainer=true

表单之间没有功能父子关系.

我的意思是，Form仍然具有父级的属性 System.Windows.Forms.Control.Parent和System.Window.Forms.Control.Controls，但是如果您尝试使一种形式成为另一种形式的子代，则这些属性将失效.将引发异常.

有一种解决方法，但我建议不要使用它.您可以将Form.TopLevel属性分配为false，然后可以将这种形式作为其他形式的子项插入.看起来很难看.如果子窗体具有非客户区，则父窗体将与所有非客户区一起进入父窗体.

Windows并非真正设计为使用此类病理性事物.这将违反大多数基本设计原则.同样，这是永远不需要的.对于Form的子级，可以使用其他容器控件，例如Panel，TabControl等.

我没有提到非常不同的关系:MDI父级和MDI子级之间.这是完全不同的故事，但是我不建议使用MDI.即使Microsoft也不建议这样做.您不必折磨头，也不必用这种丑陋的风格吓users用户.

上面引用了我过去的一些答案，我将解释您可以做什么.

There is no functional child-parent relationship between forms.

I mean, Form still have child-parent properties System.Windows.Forms.Control.Parent and System.Window.Forms.Control.Controls but these properties are made defunct if you try to make one form a child of another form. An exception will be thrown.

There is a work-around, but I would advise not to use it. You can assign Form.TopLevel property to false, and then such form could be inserted as a child of another form. It will look ugly. If the child form has non-client area, the parent form will go inside the parent form with all the non-client area.

Windows is not really designed to use such pathological things. This would violate most basic design principles. Also, this is never needed. For a children of the Form you can use other container controls like Panel, TabControl and the like.

Please see my past answer on this topic: Parent Child Form Relationship[^].

http://msdn.microsoft.com/en-us/library/system.windows.forms.tabcontrol.aspx[^].

I did not mention a very different relationship: between MDI parent and MDI children. This is totally different story, but I don''t recommend using MDI. It is highly discouraged even by Microsoft. You don''t need to torture your head and scare off you users with this ugly style.
