Array class static methods for common array manipulations.

Demo Code

using System;/*  www  .  j  a v  a 2  s  .co  m*/
using static System.Array;
using System.Collections;
class UsingArray
{
   private static int[] intValues = { 1, 2, 3, 4, 5, 6 };
   private static double[] doubleValues = { 8.4, 9.4, 0.4, 7.4, 1.4 };
   private static int[] intValuesCopy;
   static void Main()
   {
      intValuesCopy = new int[intValues.Length]; // defaults to zeroes
      PrintArrays(); // output initial array contents
      // sort doubleValues
      Sort(doubleValues); // unqualified call to Array static method Sort
      // copy intValues into intValuesCopy
      Array.Copy(intValues, intValuesCopy, intValues.Length);
      Console.WriteLine("\nArray values after Sort and Copy:\n");
      PrintArrays(); // output array contents
      Console.WriteLine();
      // search for 5 in intValues
      int result = Array.BinarySearch(intValues, 5);
      Console.WriteLine(result >= 0 ? $"5 found at element {result} in intValues" : "5 not found in intValues");
      // search for 8763 in intValues
      result = Array.BinarySearch(intValues, 8763);
      Console.WriteLine(result >= 0 ? $"8763 found at element {result} in intValues" : "8763 not found in intValues");
   }
   private static void PrintArrays()
   {
      Console.Write("doubleValues: ");
      IEnumerator enumerator = doubleValues.GetEnumerator();
      while (enumerator.MoveNext())
      {
         Console.Write($"{enumerator.Current} ");
      }
      Console.Write("\nintValues: ");
      enumerator = intValues.GetEnumerator();
      while (enumerator.MoveNext())
      {
         Console.Write($"{enumerator.Current} ");
      }
      Console.Write("\nintValuesCopy: ");
      // iterate through the second int array with a foreach statement
      foreach (var element in intValuesCopy)
      {
         Console.Write($"{element} ");
      }
      Console.WriteLine();
   }
