Read Contacts Error

[RBC]

Hi,

I get following message in my code below:

Unable to cast COM object of type 'System.__ComObject' to interface type
'Microsoft.Office.Interop.Outlook.ContactItem'. This operation failed because
the QueryInterface call on the COM component for the interface with IID

What is missing in my code?

Thank you,
Rune

private void m_CONTACTS_method()
{
Int32 vm_COUNTER_ROW_Int32 = 0;

try

DataTable o_DataTable_Contact = new DataTable();
o_DataTable_Contact.Columns.Add( "FirstName" );
o_DataTable_Contact.Columns.Add( "LastName" );
o_DataTable_Contact.Columns.Add( "EmailAddress" );

o_DataTable_Contact.Columns.Add( "Address" );
