I am calling a method that returns a List variable that contains a c# Anonymous Type objects. For example:

List list = new List()

    You cannot do this with anonymous types. Just create a Contact class/struct and use that. 
    


    List list = new List();
foreach ( Contact c in allContacts ) {
    list.Add( c );
}



    Then you can do this:
    


    foreach ( var o in list ) {
    Console.WriteLine( o.ContactID );
}

    


    ...or this:
    


    foreach ( object o in list ) {
    Console.WriteLine( ((Contact)o).ContactID ); //Gives intellisense
}

    


    Of course you should in that case just do create a Contact list instead of an object list:
    


    List list = new List();
foreach ( Contact c in allContacts ) {
    list.Add( c );
}
