JScript does not support generic types and methods.

Type Parameters

  • TSource
    The type of source.

  • TOther
    The other type.


  • source
    Type: System.IObservable<TSource>
    The source sequence to propagate elements for.

  • other
    Type: System.IObservable<TOther>
    The observable sequence that terminates propagation of elements of the source sequence.

Return Value

Type: System.IObservable<TSource>
An observable sequence containing the elements of the source sequence up to the point the other sequence interrupted further propagation.

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 .
