C# Array ConvertAll

Description

Array ConvertAllconverts an array of one type to an array of another type.

Syntax

Array.ConvertAll has the following syntax.


public static TOutput[] ConvertAll<TInput, TOutput>(
  TInput[] array,
  Converter<TInput, TOutput> converter
)

Parameters

Array.ConvertAll has the following parameters.

TInput - The type of the elements of the source array.
TOutput - The type of the elements of the target array.
array - The one-dimensional, zero-based Array to convert to a target type.
converter - A Converter that converts each element from one type to another type.

Returns

Array.ConvertAll method returns

Example

The following code example defines a method named PointFToPoint that converts a PointF structure to a Point structure.


using System;//from   www .  jav a  2 s . c  o  m
using System.Drawing;
using System.Collections.Generic;

public class Example
{
    public static void Main()
    {
        PointF[] apf = {
            new PointF(7.8F, 3.2F),
            new PointF(9.3F, 7.73F),
            new PointF(7.5F, 2.2F) };

        Point[] ap = Array.ConvertAll(apf, new Converter<PointF, Point>(PointFToPoint));
        foreach( Point p in ap )
        {
            Console.WriteLine(p);
        }
    }

    public static Point PointFToPoint(PointF pf)
    {
        return new Point(((int) pf.X), ((int) pf.Y));
    }
}

The code above generates the following result.
