public View<TResult> SelectMany<TCollection,TResult>( 
   System.Linq.Expressions.Expression<Func<T,IObservableSource<TCollection>>> collectionSelector,
   System.Linq.Expressions.Expression<Func<T,TCollection,TResult>> resultSelector
)

Parameters

collectionSelector: A transform function to apply to each element of this view.
resultSelector: A transform function to apply to each element of the intermediate collection.

Type Parameters

TCollection: The type of the intermediate elements collected by collectionSelector.
TResult: The type of the elements of the resulting view.
