ParallelEnumerable.SkipWhile<TSource> Method (ParallelQuery<TSource>, Func<TSource, Int32, Boolean>)

Bypasses elements in a parallel sequence as long as a specified condition is true and then returns the remaining elements. The element's index is used in the logic of the predicate function.

Namespace:  System.Linq
Assembly:  System.Core (in System.Core.dll)
public static ParallelQuery<TSource> SkipWhile<TSource>(
	this ParallelQuery<TSource> source,
	Func<TSource, int, bool> predicate
)

Type Parameters

TSource

The type of elements of source.

Parameters

source
Type: System.Linq.ParallelQuery<TSource>

The sequence to return elements from.

predicate
Type: System.Func<TSource, Int32, Boolean>

A function to test each source element for a condition; the second parameter of the function represents the index of the source element.

Return Value

Type: System.Linq.ParallelQuery<TSource>
A sequence that contains the elements from the input sequence starting at the first element in the linear series that does not pass the test specified by predicate.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type ParallelQuery<TSource>. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).
