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

predicate

Type: 'T -> bool

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

source

Type: seq<'T>

The input sequence.

Exception

Condition

ArgumentNullException

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
16 25 36 49 64 81 100
