problem whith C# Microsoft.Offic e.Interop.Outlo ok namespace (null reference)

[JC]

Anybody knows what problem has this code? I think, in the Garbage
Collector? You know the Solution?
The program in the test's case, whit 350 contacts, run OK before number
86. The error is a "Array index out of bounds".
Microsoft.Offic e.Interop.Outlo ok._Application olApp = new
Microsoft.Offic e.Interop.Outlo ok.ApplicationC lass();
Microsoft.Offic e.Interop.Outlo ok._NameSpace olNs =
olApp.GetNamesp ace("MAPI");
Microsoft.Offic e.Interop.Outlo ok.MAPIFolder aContacts =
olNs.GetDefault Folder(Microsof t.Office.Intero p.Outlook.OlDef aultFolders.olF olderContacts);
Microsoft.Offic e.Interop.Outlo ok.Items oItems = aContacts.Items ;
FAddressBookNam e = aContacts.Addre ssBookName;
foreach (Microsoft.Offi ce.Interop.Outl ook._ContactIte m oContact in
oItems)
{

//do something
}

Microsoft.Offic e.Interop.Outlo ok._Application olApp = new
Microsoft.Offic e.Interop.Outlo ok.ApplicationC lass();

Microsoft.Offic e.Interop.Outlo ok._NameSpace olNs =

Microsoft.Offic e.Interop.Outlo ok.MAPIFolder aContacts =

Microsoft.Offic e.Interop.Outlo ok.Items oItems =
aContacts.Items ;

for (int i = 0; i <= x; oItems.Count)

{ //Explota en la proxima linea.

Microsoft.Offic e.Interop.Outlo ok._ContactItem oContact =
(Microsoft.Offi ce.Interop.Outl ook._ContactIte m)oItems[i];

//Do something with oContact

oContact = null;

}

In this second case, the error appear in the line before the "for".

Microsoft.Offic e.Interop.Outlo ok._Application olApp = new

Microsoft.Offic e.Interop.Outlo ok._NameSpace olNs =

Microsoft.Offic e.Interop.Outlo ok.MAPIFolder aContacts =

Microsoft.Offic e.Interop.Outlo ok.Items oItems =

int x = oItems.Count;

//Do something with oContact

oContact = null;

}

If you think the problem is the Garbage Collector is not collecting
memory that is free, you can programmaticall y instruct the GC to
collect the garbage with the following line of code.

GC.Collect();

That said, I don't think a problem with the GC would cause the error
message you saw. Can you post what happens in the foreach loop b/c it
seems to me that is where you are overreaching your array size.

Forget about the GC, just run your code through the debugger and watch the
index when it throws. Anyway, the piece of code you post is not the cause,
it's the "do something" which goes wrong
