处置TabPage控件及其控件

Question

My application uses TabControl to show data, each time the user asks for data the application will create a new TabPage which contains many controls ( PictureBox controls, Label controls, .etc). The user at some point will close the TabPage controls he is done working with. Now the problem here is the closed TabPage controls, they will pile up in the memory causing the program to use a huge part of the memory. Removing the TabPage controls from the TabControl does not dispose it nor dispose the items within, it just hides it but the control still hangs in the memory.

The code I am using to remove the TabPage is something like:

tabControl.TabPages.Remove(myTabPage);
myTabPage.Dispose();   

Q: How do I totally get rid of the TabPage controls?

Answer 1

您可以每次都通过与其关联的选项卡控件进行迭代，并将其循环放置。

            tabControl1.TabPages[0].Controls[i].Dispose();

Answer 2

Calling myTabPage.Dispose() should dispose the resource of the TabPage and its children. However, the memory used by these objects might not be necessarily released right away by GC, even if these objects are not referenced by the others.

In a computer with very large memory, GC tends to be lazy. As long as the memory will be released later, say, minutes later, you don't need to worry.
