Returns a read-only IList{T} wrapper for the current collection.

Namespace: OSIsoft.AF
Assembly: OSIsoft.AFSDK (in OSIsoft.AFSDK.dll) Version: 3.1.1.1182

Syntax

public IList<T> AsReadOnly()

Public Function AsReadOnly As IList(Of T)

Dim instance As AFNamedCollectionList
Dim returnValue As IList(Of T)

returnValue = instance.AsReadOnly()

public:
IList<T>^ AsReadOnly()

member AsReadOnly : unit -> IList<'T>

Return Value

Type: IListT
Returns a read-only IList{T} wrapper for the current collection.

Remarks

A collection that is read-only is simply a collection with a wrapper that prevents modifying the collection. Therefore, if changes are made to the underlying collection, the read-only collection reflects those changes.
