Returns a connectable observable sequence that shares a single subscription to the underlying sequence and starts with initialValue.
Assembly: System.Reactive (in System.Reactive.dll)
[ExtensionAttribute] public: generic<typename TSource, typename TResult> static IObservable<TResult>^ Publish( IObservable<TSource>^ source, Func<IObservable<TSource>^, IObservable<TResult>^>^ selector, TSource initialValue )
The type of source.
The type of Result.
- Type: System::IObservable<>
The source sequence whose elements will be multicasted through a single shared subscription.
- Type: System::Func<IObservable<>, IObservable<>>
The selector function which can use the multicasted source sequence as many times as needed, without causing multiple subscriptions to the source sequence.
The initial value received by observers upon subscription.
Return ValueType: System::IObservable<>
An observable sequence that contains the elements of a sequence produced by multicasting the source sequence within a selector function.
