Answers for "c# array.copy"

how to copy one array value to another without reference c#

var source = new[] { "Ally", "Bishop", "Billy" };
var target = new string[4];

source.CopyTo(target, 1);

foreach (var item in target)
{
  Console.WriteLine(item);
}

// output:

// Ally
// Bishop
// Billy

copy a list C#

using System;
using System.Linq;
using System.Collections.Generic;

List<string> source = new List<string>() { "A", "B", "C" };
 
List<string> clonedList = source.ToList();
Console.WriteLine(String.Join(",", clonedList));

// Result = A,B,C

c# array.clone

using System;

      // Create a clone of the CultureInfo array.
      CultureInfo[] arrCIClone = (CultureInfo[]) arrCI.Clone();

      // Replace an element in the clone array.
      CultureInfo ci4 = new CultureInfo( "th-TH", false );
      arrCIClone[0] = ci4;

      // Display the contents of the original array.
      Console.WriteLine( "The original array contains the following values:" );
      PrintIndexAndValues( arrCI );

      // Display the contents of the clone array.
      Console.WriteLine( "The clone array contains the following values:" );

   public static void PrintIndexAndValues( Array myArray )  {

/* 
This code produces the following output.

The original array contains the following values:
        [0]:    ar-SA
        [1]:    en-US
        [2]:    fr-FR
        [3]:    ja-JP
The clone array contains the following values:
        [0]:    th-TH
        [1]:    en-US
        [2]:    fr-FR
        [3]:    ja-JP
Before changes to the clone:
   Original: The DateTimeFormatInfo.DateSeparator for ja-JP is /.
      Clone: The DateTimeFormatInfo.DateSeparator for ja-JP is /.
After changes to the clone:
   Original: The DateTimeFormatInfo.DateSeparator for ja-JP is -.
      Clone: The DateTimeFormatInfo.DateSeparator for ja-JP is -.
