C# Sharp Exercises: Compare four sets of words by using each member of the StringComparison enumeration

C# Sharp String: Exercise-25 with Solution

Write a C# Sharp program to compares four sets of words by using each member of the StringComparison enumeration. The comparisons use the conventions of the English (United States) and Sami (Upper Sweden) cultures.
Note: that the strings "encyclopedia" and "encyclopedia" are considered equivalent in the en-US culture but not in the Sami (Northern Sweden) culture.

Sample Solution:-

C# Sharp Code:

using System;
using System.Globalization;
using System.Threading;

public class Example25
{
   public static void Main()
   {
      String[] cultureNames = { "en-AU", "sv-SE" };
      String[] strs1 = { "case",  "encyclopedia",  
                            "encyclopedia", "Archeology" };
      String[] strs2 = { "Case", "encyclopedia", 
                            "encyclopedia" , "ARCHEOLOGY" };
      StringComparison[] comparisons = (StringComparison[]) Enum.GetValues(typeof(StringComparison));

      foreach (var cultureName in cultureNames) {
         Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(cultureName);
         Console.WriteLine("Current Culture: {0}", CultureInfo.CurrentCulture.Name);
         for (int ctr = 0; ctr <= strs1.GetUpperBound(0); ctr++) {
            foreach (var comparison in comparisons) 
               Console.WriteLine("   {0} = {1} ({2}): {3}", strs1[ctr],
                                 strs2[ctr], comparison, 
                                 String.Equals(strs1[ctr], strs2[ctr], comparison));

            Console.WriteLine();         
         }
         Console.WriteLine();
      }
   }
}

Sample Output:

Current Culture: en-AU                                                                                        
   case = Case (CurrentCulture): False                                                                        
   case = Case (CurrentCultureIgnoreCase): True                                                               
   case = Case (InvariantCulture): False                                                                      
   case = Case (InvariantCultureIgnoreCase): True                                                             
   case = Case (Ordinal): False                                                                               
   case = Case (OrdinalIgnoreCase): True          
------
Archeology = ARCHEOLOGY (CurrentCulture): False                                                            
   Archeology = ARCHEOLOGY (CurrentCultureIgnoreCase): True                                                   
   Archeology = ARCHEOLOGY (InvariantCulture): False                                                          
   Archeology = ARCHEOLOGY (InvariantCultureIgnoreCase): True                                                 
   Archeology = ARCHEOLOGY (Ordinal): False                                                                   
   Archeology = ARCHEOLOGY (OrdinalIgnoreCase): True
