A question to clarify the "Release Com Objects yourself" thing...

Does that mean that I cannot have code like this:


for (int i=1;i<Fold.Folders.Count;i++)

or even

cnt=Fold.Folders.Count;

because I am creating COM objects while doing that and since I don't have vars that point to them I cannot release them?

Hi Mike,

Exactly.Instead you need to have a variable containing Fold.Folders. Say: 

Outlook.Folders folders = Fold.Folders;
for (int i=1;i<Fold.Folders.Count;i++) 
{
   //
}
Marshal.ReleaseComObject(folders)


When using COM objects, the Release stage in the Get-Use-Release sequence should be coded explicitely. Other interesting restrictions are described in http://www.add-in-express.com/creating-addins-blog/2008/10/30/releasing-office-objects-net/
