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

Syntaxpublic static IList<T> TypedAs<T>(
IList untypedList
)
public:
generic<typename T>
static IList<T>^ TypedAs(
IList^ untypedList
)
Parameters
- untypedList
- Type: System.CollectionsIList
An untyped list. This list should only contain
items of type T or a type derived from it.
Type Parameters
- T
- The item type of the wrapper list.
Return Value
Type:
IListTA generic IList<T> wrapper around
untypedList.
If
untypedList is null, then null is returned.
RemarksSome collections implement both generic and non-generic interfaces. For efficiency,
this method will first attempt to cast untypedList to IList<T>.
If that succeeds, it is returned; otherwise, a wrapper object is created.
