Type Parameters

  • TSource

Parameters

  • source
    Type: System.IObservable<TSource>
    Observable sequence to subscribe to.

  • onNext
    Type: System.Action<TSource>
    Action to invoke for each element in the observable sequence.

  • onCompleted
    Type: System.Action
    Action to invoke upon graceful termination of the observable sequence.

Return Value

Type: System.IDisposable
IDisposable object used to unsubscribe from the observable 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 .
