How to get user picture using Lync APIs

I was exploring the Lync APIs after installing Lync SDK on my machine and as a curiosity tried to display the users communicator / Lync Image in custom control.

To get the following example working – you will need to install the Lync SDK or add the references of Lync APIs to your project. Lync SDK can be downloaded here , after this – add the references from location [%root%]\Program Files (x86)\Microsoft Lync\SDK\Assemblies\Desktop\Microsoft.LyncModel.dll to your project.

I created one sample Silverlight project where I took Silverlight image control and tried to provide the source. This control takes source as either full path of image or you can assign the BitMap Imag stream.

I created one entity class named – UserEntity which holds BitMapImage as a property.

public class UserEntity

{

    public BitmapImage UserImage { get; set; }

}

Here is the xaml for Silverlight control , Binding is added as BitMapImage stream

<Image Name="userImage" Source="{Binding Path=UserImage}" Margin="2,2,2,2" Height="40" Width="40"></Image>

Now the function to get user image

public partial class MainPage : UserControl

{

  List<UserEntity> allUsers = new List<UserEntity>();

  LyncClient client;

    public MainPage()

  {

    InitializeComponent();

    client = LyncClient.GetClient();

   

    UserEntity userObjet = new UserEntity();

    if (client != null)

    {                    

       ContactManager cManager = client.ContactManager;

       if (cManager != null)

       {

         Contact contact = cManager.GetContactByUri("useremail@domain.com");

         if (contact != null)

         {

           List<ContactInformationType> ciList = new List<ContactInformationType>();

           ciList.Add(ContactInformationType.Photo);

           IDictionary<ContactInformationType, object> dic = null;

           dic = contact.GetContactInformation(ciList);

           if (dic != null)

           {

             Stream photoStream = dic[ContactInformationType.Photo] as Stream;

             if (photoStream != null)

             {

               BitmapImage userImageBitMap = new BitmapImage();

               userImageBitMap.SetSource(photoStream);

               userObjet.UserImage = userImageBitMap;

             }

           }

         }

      }

    }

         allUsers.Add(userObjet);

  if (allUsers != null && allUsers.Count > 0)

         {

           userImage.ItemsSource = allUsers;

  }

  }
