The ToArray<TSource>(IEnumerable<TSource>) method forces immediate query evaluation and returns an array that contains the query results. You can append this method to your query in order to obtain a cached copy of the query results.

ToList<TSource> has similar behavior but returns a List<T> instead of an array.

The following code example demonstrates how to use ToArray<TSource> to force immediate query evaluation and return an array of results.
