source

Return Value

Type: System.Collections.Generic.List(TSource)

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IEnumerable(TSource). When you use instance method syntax to call this method, omit the first parameter.

ExceptionCondition
ArgumentNullException

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

The ToList(TSource)(IEnumerable(TSource)) method forces immediate query evaluation and returns a List(T) that contains the query results. You can append this method to your query in order to obtain a cached copy of the query results.

ToArray(TSource) has similar behavior but returns an array instead of a List(T).

The following code example demonstrates how to use ToList(TSource) to force immediate query evaluation and return a List(T) that contains the query results.
