Returns a read-only view onto a collection. The returned ICollection<T> interface only allows operations that do not change the collection: GetEnumerator, Contains, CopyTo, Count. The ReadOnly property returns false, indicating that the collection is read-only. All other methods on the interface throw a NotSupportedException.

Namespace: Wintellect.PowerCollections
Assembly:  PowerCollections (in PowerCollections.dll)

Return Value

A read-only view onto collection. If collection is null, then null is returned.
