Usage Note

ExceptionCondition
ArgumentNullException

source is a null reference (Nothing in Visual Basic).

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.
