AlgorithmsTypedAsT Method (ICollection) |
Given a non-generic ICollection interface, wrap a generic ICollection<T>
interface around it. The generic interface will enumerate the same objects as the
underlying non-generic collection, but can be used in places that require a generic interface.
The underlying non-generic collection must contain only items that
are of type T or a type derived from it. This method is useful
when interfacing older, non-generic collections to newer code that uses generic interfaces.

Syntaxpublic static ICollection<T> TypedAs<T>(
ICollection untypedCollection
)
public:
generic<typename T>
static ICollection<T>^ TypedAs(
ICollection^ untypedCollection
)
Parameters
- untypedCollection
- Type: System.CollectionsICollection
An untyped collection. This collection should only contain
items of type T or a type derived from it.
Type Parameters
- T
- The item type of the wrapper collection.
Return Value
Type:
ICollectionTA generic ICollection<T> wrapper around
untypedCollection.
If
untypedCollection is null, then null is returned.
RemarksSome collections implement both generic and non-generic interfaces. For efficiency,
this method will first attempt to cast untypedCollection to ICollection<T>.
If that succeeds, it is returned; otherwise, a wrapper object is created.
Unlike the generic interface, the non-generic ICollection interfaces does
not contain methods for adding or removing items from the collection. For this reason,
the returned ICollection<T> will be read-only.
