The image below shows the result:

xpCollection1.Filter = new ContainsOperator("Addresses", new BinaryOperator("City", "Chicago"));
//or
xpCollection1.Filter = CriteriaOperator.Parse("[Addresses][[City] = ?]", "Chicago");

xpCollection1.Filter = New ContainsOperator("Addresses", New BinaryOperator("City", "Chicago"))
'or
xpCollection1.Filter = CriteriaOperator.Parse("[Addresses][[City] = ?]", "Chicago")
