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.

Given a non-generic IEnumerable interface, wrap a generic IEnumerable<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.

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.
