For Method

In This Topic

Executes a for-loop in which iterations may run in parallel.

Syntax

Visual Basic
C#

'Declaration
 
Public Shared Sub For( _
   ByVal start As System.Integer, _
   ByVal stop As System.Integer, _
   ByVal loopBody As NParallel.ForLoopBody _
)

'Usage
 
Dim start As System.Integer
Dim stop As System.Integer
Dim loopBody As NParallel.ForLoopBody
 
NParallel.For(start, stop, loopBody)

public static void For( 
   System.int start,
   System.int stop,
   NParallel.ForLoopBody loopBody
)

Parameters

start: Loop's start index.
stop: Loop's stop index.
loopBody: Loop's body.

Remarks

The method is used to parallel for-loop running its iterations in different threads. The start and stop parameters define loop's starting and ending loop's indexes. The number of iterations is equal to stop - start.

Sample usage:

Parallel.For( 0, 20, delegate( int i ) // which is equivalent to // for ( int i = 0; i < 20; i++ ) { System.Diagnostics.Debug.WriteLine( "Iteration: " + i ); // ... } );

Requirements

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
