  6. The questions are good. All these questios reflect framework 1.1. Many versions released like 2.0, 3.0, 3.5 and 4.0 is in beta now.

    It would be nice to all by including the different new things coming out from version to version. So the questions become complete and can ace any .net interview.

    Which one of the following is a limitation resulting from a class that has an indexer property but does NOT either implement the IEnumerable interface or any of its members?
    1. The class cannot implement a GetEnumerator method.
    2. The indexer can have only one parameter.
    3. Neither the "for" nor "foreach" statements is supported.
    4. The "foreach" is not supported.
    5. The indexer must return an "object" type.
