Enumerable.SkipWhile<'TSource> Method (IEnumerable<'TSource>, Func<'TSource, Boolean>)
Bypasses elements in a sequence as long as a specified condition is true and then returns the remaining elements.
Assembly: System.Core (in System.Core.dll)
static member SkipWhile<'TSource> : source:IEnumerable<'TSource> * predicate:Func<'TSource, bool> -> IEnumerable<'TSource>
An IEnumerable<'T> to return elements from.
Return ValueType: System.Collections.Generic.IEnumerable<'TSource>
An IEnumerable<'T> 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.
The type of the elements of source.
Themethod is implemented by using deferred execution. The immediate return value is an object that stores all the information that is required to perform the action. The query represented by this method is not executed until the object is enumerated either by calling its GetEnumerator method directly or by using foreach in Visual C# or For Each in Visual Basic.
This method tests each element of source by using predicate and skips the element if the result is true. After the predicate function returns false for an element, that element and the remaining elements in source are yielded and there are no more invocations of predicate.
If predicate returns true for all elements in the sequence, an empty IEnumerable<'T> is returned.
The TakeWhile and SkipWhile methods are functional complements. Given a sequence coll and a pure function p, concatenating the results of coll.TakeWhile(p) and coll.SkipWhile(p) yields the same sequence as coll.
In Visual Basic query expression syntax, a Skip While clause translates to an invocation of SkipWhile.
