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).| Exception | Condition |
|---|---|
| ArgumentNullException | source or predicate is a null reference (Nothing in Visual Basic). |
| OperationCanceledException | The query was canceled with the token passed in through WithCancellation. |
| OverflowException | More than MaxValue elements are enumerated by the query. |
| AggregateException | One or more exceptions occurred during the evaluation of the query. |
