Type Parameters
- TSource
The type of source.
- TOther
The type of result.
Parameters
- source
Type: System.Reactive.Linq.IQbservable<TSource>
A queryable observable sequence of elements to project.
- other
Type: System.IObservable<TOther>
A transform function to apply to each element.
Return Value
Type: System.Reactive.Linq.IQbservable<TOther>
