Parameters
- first
- Type: System.Linq..::.ParallelQuery<(Of <(TFirst>)>)
This parameter is not used.
- second
- Type: System.Collections.Generic..::.IEnumerable<(Of <(TSecond>)>)
This parameter is not used.
- resultSelector
- Type: System..::.Func<(Of <(TFirst, TSecond, TResult>)>)
This parameter is not used.
Type Parameters
- TFirst
- This type parameter is not used.
- TSecond
- This type parameter is not used.
- TResult
- This type parameter is not used.
Return Value
This overload always throws a NotSupportedException.Remarks
This overload exists to disallow usage of Zip with a left data source of type
ParallelQuery<(Of <(TSource>)>) and a right data source of type IEnumerable<(Of <(T>)>).
Otherwise, the Zip operator would appear to be bind to the parallel implementation, but would in reality bind to the sequential implementation.
