Dispose or else suffer

This is really cool thing I got it from my colleage ...heres the link.

A few highlights from the same:

1.“If your object has a Dispose method, call it as soon as you are done with the object.”

2.WARNING: Do not write code like this or your hair may fall out, your peers will likely laugh at you, and your code will certainly be suboptimal.

GC.Collect();
GC.WaitForPendingFinalizers();

You could also have used simply:
GC.GetTotalMemory(true);

3.Note: you will need to make sure that you build a release optimized version of your assembly (i.e. without debug settings). When the runtime encounters a debug assembly, it intentionally prolongs the lifetime of managed objects through the entire scope of a method call to ease debugging. As a result, the runtime keeps the file open through the entire method, and won’t free it up after it’s last use.
