Right now I'm using the the LyncClient.ContactManager.BeginSearch method to find contacts. However, I haven't been able to figure out how to get all the contacts. I've tried passing "*" and "%" as wild-card characters but that has not worked. Right now here is my function call.
_lyncClient.ContactManager.BeginSearch("*", SearchProviders.GlobalAddressList, SearchFields.DisplayName, SearchOptions.ContactsOnly, 400, SearchCallback, "Searching Contacts");
Lync contacts are organised into groups, so you need to start at the Groups level. Once you've got a group, you can then enumerate through it's Contacts
foreach(var group in _client.ContactManager.Groups)
{
foreach (var contact in group)
{
MessageBox.Show(contact.Uri);
}
}
This article is good for background, and more advanced features
Edit: Specifically, for the distribution groups expansion question, I think the sample here is flawed.
Instead of calling BeginExpand and waiting on the WaitHandle, provide a callback method to handle the Expand callback. So, instead of:
asyncOpResult = DGGroup.BeginExpand(null, null);
asyncOpResult.AsyncWaitHandle.WaitOne();
DGGroup.EndExpand(asyncOpResult);
try this:
...
asyncOpResult = DGGroup.BeginExpand(ExpandCallback, DGGroup);
...
public void ExpandCallback(IAsyncResult ar)
{
DistributionGroup DGGroup = (DistributionGroup)ar.AsyncState;
DGGroup.EndExpand(ar);
etc...
}
This works perfectly for me.
