Type Parameters
- TSource
The type of source.
- TOther
The other type.
Parameters
- source
Type: System.IObservable<TSource>
An observable sequence of elements to project.
- other
Type: System.IObservable<TOther>

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 .
