ParallelEnumerable::Zip<TFirst, TSecond, TResult> Method (ParallelQuery<TFirst>^, IEnumerable<TSecond>^, Func<TFirst, TSecond, TResult>^)
This Zip overload should never be called. This method is marked as obsolete and always throws NotSupportedException when invoked.
Assembly: System.Core (in System.Core.dll)
public: generic<typename TFirst, typename TSecond, typename TResult> [ExtensionAttribute] [ObsoleteAttribute("The second data source of a binary operator must be of type System.Linq.ParallelQuery<T> rather than System.Collections.Generic.IEnumerable<T>. To fix this problem, use the AsParallel() extension method to convert the right data source to System.Linq.ParallelQuery<T>.")] static ParallelQuery<TResult>^ Zip( ParallelQuery<TFirst>^ first, IEnumerable<TSecond>^ second, Func<TFirst, TSecond, TResult>^ resultSelector )
Parameters
- first
-
Type:

- resultSelector
-
Type:
System::Func<TFirst, TSecond, TResult>^
This parameter is not used.
Return Value
Type: System.Linq::ParallelQuery<TResult>^This overload always throws a NotSupportedException.

- TSecond
This type parameter is not used.
- TResult
This type parameter is not used.
| Exception | Condition |
|---|---|
| NotSupportedException | The exception that occurs when this method is called. |
This overload exists to disallow usage of Zip with a left data source of type ParallelQuery<TSource> and a right data source of type IEnumerable<T>. Otherwise, the Zip operator would appear to be bind to the parallel implementation, but would in reality bind to the sequential implementation.
