JScript does not support generic types and methods.

Type Parameters

  • TSource
    The type of source.


  • first
    Type: System.IObservable<TSource>
    The first observable sequence whose exception (if any) is caught.
  • second
    Type: System.IObservable<TSource>
    Second observable sequence used to produce results after the first sequence terminates.

Return Value

Type: System.IObservable<TSource>
An observable sequence that concatenates the first and second sequence, even if the first sequence terminates exceptionally.

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 .
