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

Visual Studio 2012

Visual Studio 2010

Wraps the two given enumerations as a single concatenated enumeration.

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

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

// Signature:
Seq.append : seq<'T> -> seq<'T> -> seq<'T>

// Usage:
Seq.append source1 source2

source1

Type: seq<'T>

The first sequence.

source2

Type: seq<'T>

The second sequence.

Exception	Condition
ArgumentNullException	Thrown when either of the two provided sequences is null.

The result sequence.

The returned sequence may be passed between threads safely. However, individual IEnumerator<T> values generated from the returned sequence should not be accessed concurrently.

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

The following example hows how to use Seq.append.

printfn "%A" (Seq.append [| 1; 2; 3|] [ 4; 5; 6])

Output

seq [1; 2; 3; 4; ...]
