Sie können verwenden Array.Find(T) Methode, um diese Aufgabe zu erfüllen.
public static T Find<T>(
T[] array,
Predicate<T> match
)
Zum Beispiel,
using System;
using System.Drawing;
public class Example
{
public static void Main()
{
// Create an array of five Point structures.
Point[] points = { new Point(100, 200),
new Point(150, 250), new Point(250, 375),
new Point(275, 395), new Point(295, 450) };
// To find the first Point structure for which X times Y
// is greater than 100000, pass the array and a delegate
// that represents the ProductGT10 method to the static
// Find method of the Array class.
Point first = Array.Find(points, ProductGT10);
// Note that you do not need to create the delegate
// explicitly, or to specify the type parameter of the
// generic method, because the C# compiler has enough
// context to determine that information for you.
// Display the first structure found.
Console.WriteLine("Found: X = {0}, Y = {1}", first.X, first.Y);
}
// This method implements the test condition for the Find
// method.
private static bool ProductGT10(Point p)
{
if (p.X * p.Y > 100000)
{
return true;
}
else
{
return false;
}
}
}
/* This code example produces the following output:
Found: X = 275, Y = 395
*/
