Question : C# Brain Bench Question

I'm new to this 'IEnumerable interface'.   Can someone say a word or two about it as in contrast to the world before .NET ?

Thanks!


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?

Choice 1.The indexer must return an "object" type.
Choice 2.Neither the "for" nor "foreach" statements is supported.
Choice 3.The "foreach" is not supported.
Choice 4.The indexer can have only one parameter.
Choice 5.The class cannot implement a GetEnumerator method.

Hello,
IEnumerable interface is the base for using foreach statement.
Although you can use a for loop; a foreach statement is easier to use.
