# IReadOnlyList(Of T) Interface

**.NET Framework 4.6 and 4.5**

Represents a read-only collection of elements that can be accessed by index.

**Namespace:**System.Collections.Generic

**Assembly:**mscorlib (in mscorlib.dll)

#### Type Parameters

- Out T
The type of elements in the read-only list.

This type parameter is covariant. That is, you can use either the type you specified or any type that is more derived. For more information about covariance and contravariance, see Covariance and Contravariance in Generics.
