Iterating a Contacts folder for Outlook 2003 and 2007 in C#

I need to iterate through all of the contacts in a contact folder. I have

tried two methods to get the contacts out of a Contact folder: Here is the

first code I've tried:

Outlook.Application Outlook = new Outlook.Application();

Outlook.MAPIFolder fldContacts =

(Outlook.MAPIFolder)Outlook.Session.GetDefaultFolder(OlDefaultFolders.olFolderContacts);

foreach (Outlook.ContactItem oItem1 in fldContacts.Items)

{//Get each contact...}

I get the following complile error when I attempt the above:

foreach statement cannot operate on variables of type 'Outlook.Items'

because 'Outlook.Items' does not contain a public definition for

'GetEnumerator'

Then I tried this approach:

Outlook.ContactItem oItem;

for (int j = 0; j < oContactFolder.Items.Count; j++)

{

if (j == 0)

oItem = (Outlook.ContactItem)oContactFolder.Items.GetFirst();

else

oItem = (Outlook.ContactItem)oContactFolder.Items.GetNext();

But with the above approach I'm getting the first contact, and a second, but

from that point on it keeps returning the same second record (out of 20

total).

Can anyone help me see what I am doing wrong here? It really shouldn't be

that difficult to accomplish what I am trying to do here.

Thanks!!!!!!!!!

A contacts folder can have distribution lists in it, any code that doesn't

handle that possibility will fail in some cases. Also, Outlook collections

are 1 based and don't start at 0. You also should not concatenate dot

operators, that creates invisible object variables you cannot release,

always declare everything explicitly.

Outlook.Items items = oContactFolder.Items;

Outlook.ContactItem c = null;

if (items.Count > 0)

{

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

{

try

{

c = (Outlook.ContactItem)items; // if DL will error to catch

block

}

etc.

Now I have a new compiler problem. On the line:

c = (Outlook.ContactItem)items;

I get the following:

Cannot apply indexing with [] to an expression of type 'Outlook.Items'

I've also tried to replace with () and I get another error about trying to

use as a method.

Ideas??

No idea, that is very bizarre.

I use that type of code all the time. It compiles perfectly here. In fact, I

copied it from a working project I was just compiling.

I just tested and compiled again, and it compiled again with no errors.

There's some other problem that you have.

I am using the code you wrote to instaniate an Outlook object. I'm going to

create a new project (separate out just this code) into a new project and see

if I can see anything.

A thought occurred to me. Is this with a PIA from Add-In Express? That might

have a limitation of some sort on the enumerator of an Items collection or

using an indexed operator. The standard PIA's certainly don't have that

limitation, I use Items collections all the time in c# code.

In just looking at an Add-In Express PIA for Outlook I see that it's

exposing an Item object that takes an index value, so that looks like the

problem. Something like items.Item(i) looks like it would work.

It appears as if I've got some weird "Using Statements" One that's just

Using Outlook;

and other,

Using Outlook1 = Microsoft.Office.Interop.Outlook;

And the original DLL on the above did not allow the "foreach". I found

another DLL which does allow it, and it seemed to work with both 2003 and

2007 so I think I may be OK with that. But do you know what the first one is

pointing to? If I remove it I get a bunch of errors in the stuff you wrote

for us.

Hi Bob,


> Using Outlook;

Add-in Express provides version-neutral interops. In your case the interops

are for Outlook 2000 and Office 2000 (common tools). The namespaces

contained in these interops are Outlook and Office, respectively.


> Using Outlook1 = Microsoft.Office.Interop.Outlook;

This statement refers to PIA for some Outlook version; it may be Outlook

2002, 2003 or 2007.


> > > > c = (Outlook.ContactItem)items;

Yes, this is a kind of restriction in version-neutral interops. Try c =

items.Item(i) as Outlook.ContactItem;

Also, you may want to read my post at the Add-in Express blog on how to

support several Outlook versions in a COM add-in using different interop

versions via early and late binding, see

http://www.add-in-express.com/creating-addins-blog/2010/03/16/interop-assemblies-late-binding/.

In addition to what Andrei said if you updated your Add-In Express at any

point there might be references pointing to different paths or file names

that might need to be adjusted for a different version. For example in

loading a project created with an earlier version in the latest version of

Add-In Express I always have to adjust some references.
