Type Parameters
- TSource
The type source.
Parameters
- source
Type: System.IObservable<TSource>
The source sequence whose elements will be multicasted through a single shared subscription.
- initialValue
Type: TSource
The selector function which can use the multicasted source sequence as many times as needed, without causing multiple subscriptions to the source sequence.
Return Value
Type: System.Reactive.Subjects.IConnectableObservable<TSource>
The connectable observable sequence that shares a single subscription to the underlying sequence.
Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type IObservable<TSource>. When you use instance method syntax to call this method, omit the first parameter. For more information, see or .
