C# Disposing panels

[ania1984]

Hello,

I'm writing a program in c#, in which I create a flowlayoutpanel that contains a lot of panels. I have a button, and when the user clicks on it, I want to dispose the panels that I've created.
This is the code:

foreach (Control c in myFlowLayoutPanel.Controls)
{
    ((Panel)c).Dispose();
}

But looking at the Task Manager, I see that the memory usage doesn't decrease.
I've also tried to call to the garbage collector

GC.Collect();

but there is no difference.

Does anybody know how can I achieve this?
Thanks
