array clone method in c# code example

Example 1: clone an array c#

//arraytype newArray = array.Clone() as arraytype;
float[] newFloats = oldFloats.Clone() as float[];

Example 2: c# array.clone

using System;
using System.Globalization;

      // 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 DateTimeFormatInfo.DateSeparator for the fourth element in both arrays.
      Console.WriteLine( "Before changes to the clone:" );
      Console.WriteLine( "   Original: The DateTimeFormatInfo.DateSeparator for {0} is {1}.", arrCI[3].Name, arrCI[3].DateTimeFormat.DateSeparator );

/* 
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 -.
