T:Windows.ApplicationModel.Resources.Core.ResourceCandidateVectorView |
winrt class |
Represents a collection of ResourceCandidate objects.
A ResourceCandidateVectorView is enumerable, so you can use language-specific syntax such as foreach in C# to enumerate the items in the collection. The compiler does the type-casting for you and you won't need to cast to IEnumerable<ResourceCandidate> explicitly. If you do need to cast explicitly, for example if you want to call GetEnumerator, cast to IEnumerable<T> with a ResourceCandidate constraint.
This example is based on scenario 10 of the Application resources and localization sample. See the sample for the complete solution.
