Destroy COM object

[Jenny]

Hi all,

my ASP.NET page generates an COM object which is filled
with a lot of data (approx. 30 MB).
It is then stored in the Application-Collection to be
accessible for all users of the page.

Under some conditions I don't need this COM object anymore
and like it to be destroyed.
I'm using the following code to destroy this object:

Application.Lock()
Application.RemoveAll()
Application.Clear()
Application.UnLock()
GC.Collect()
GC.WaitForPendingFinalizers()

But the Private Memory Size increases instead of descreasing!!
Why???


Thanks in advance for all help!

Try setting the COM object to tell after all this. If this com object is
wrapped in some class you will need to call/implement dispose on it.

Hi all,

I'm using a COM DLL in order to generate an object. This
object is then stored in the application state. But after
setting it to nothing and doing a garbage collection it's
still there. Is there another way to remove such an object
completly?

Regards

use the below statement to clear the com dll.

Marshal.ReleaseComObject(objcomDll)

Note: objcomDll is the com dll name
