public:
generic <typename TSource>
[System::Runtime::CompilerServices::Extension]
 static bool All(System::Linq::ParallelQuery<TSource> ^ source, Func<TSource, bool> ^ predicate);

public static bool All<TSource> (this System.Linq.ParallelQuery<TSource> source, Func<TSource,bool> predicate);

static member All : System.Linq.ParallelQuery<'Source> * Func<'Source, bool> -> bool

<Extension()>
Public Function All(Of TSource) (source As ParallelQuery(Of TSource), predicate As Func(Of TSource, Boolean)) As Boolean

Type Parameters

TSource

The type of elements of source.

Parameters

source: ParallelQuery<TSource>

A sequence whose elements to apply the predicate to.

predicate: Func<TSource,Boolean>

A function to test each element for a condition.

Returns

Boolean

true if every element of the source sequence passes the test in the specified predicate, or if the sequence is empty; otherwise, false.
