Seq.skipWhile<'T> Function (F#)


Returns a sequence that, when iterated, skips elements of the underlying sequence while the given predicate returns true, and then yields the remaining elements of the sequence.

Namespace/Module Path: Microsoft.FSharp.Collections.Seq

Assembly: FSharp.Core (in FSharp.Core.dll)

// Signature:
Seq.skipWhile : ('T -> bool) -> seq<'T> -> seq<'T>

// Usage:
Seq.skipWhile predicate source


Type: 'T -> bool

A function that evaluates an element of the sequence to a Boolean value.


Type: seq<'T>

The input sequence.

Exception Condition




Thrown when the input sequence is null.

The result sequence.

This function is named SkipWhile in compiled assemblies. If you are accessing the function from a language other than F#, or through reflection, use this name.

The following example demonstrates the use of Seq.skipWhile. The resulting sequences contains only elements that are greater than 10.

let mySeq = seq { for i in 1 .. 10 -> i*i }
let printSeq seq1 = Seq.iter (printf "%A ") seq1; printfn ""
let mySeqSkipWhileLessThan10 = Seq.skipWhile (fun elem -> elem < 10) mySeq
mySeqSkipWhileLessThan10 |> printSeq
