C#: Compare two substrings using different cultures and ignoring the case of the substrings
Write a C# Sharp program to compare two substrings using different cultures and ignore the substring case.
Sample Solution:-
C# Sharp Code:
using System;
using System.Globalization;
// Define the Example23 class
class Example23
{
// Main method - entry point of the program
public static void Main()
{
// Define and initialize string variables
String str1 = "COMPUTER"; // String 1
String str2 = "computer"; // String 2
String str; // String to store comparison result
int result; // Result of the comparison
// Display initial strings
Console.WriteLine();
Console.WriteLine("\n str1 = '{0}', str2 = '{1}'", str1, str2);
// Ignore case, Turkish culture comparison
Console.WriteLine("Ignore case, Turkish culture:");
// Compare a substring of str1 starting at index 4 with a substring of str2 starting at index 4, each with a length of 2, ignoring case using Turkish culture
result = String.Compare(str1, 4, str2, 4, 2, true, new CultureInfo("tr-TR"));
// Determine the relationship between the compared substrings
str = ((result < 0) ? "less than" : ((result > 0) ? "greater than" : "equal to"));
// Display the comparison result
Console.Write("Substring '{0}' in '{1}' is ", str1.Substring(4, 2), str1);
Console.Write("{0} ", str);
Console.WriteLine("substring '{0}' in '{1}'.", str2.Substring(4, 2), str2);
Console.WriteLine();
// Ignore case, invariant culture comparison
Console.WriteLine("Ignore case, invariant culture:");
// Compare a substring of str1 starting at index 4 with a substring of str2 starting at index 4, each with a length of 2, ignoring case using invariant culture
result = String.Compare(str1, 4, str2, 4, 2, true, CultureInfo.InvariantCulture);
// Determine the relationship between the compared substrings
str = ((result < 0) ? "less than" : ((result > 0) ? "greater than" : "equal to"));
// Display the comparison result
Console.Write("Substring '{0}' in '{1}' is ", str1.Substring(4, 2), str1);
Console.Write("{0} ", str);
Console.WriteLine("substring '{0}' in '{1}'.\n\n", str2.Substring(4, 2), str2);
}
}
Sample Output:
str1 = 'COMPUTER', str2 = 'computer' Ignore case, Turkish culture: Substring 'UT' in 'COMPUTER' is equal to substring 'ut' in 'computer'. Ignore case, invariant culture: Substring 'UT' in 'COMPUTER' is equal to substring 'ut' in 'computer'.
Flowchart :

Go to:
PREV : Write a C# Sharp program to compare two substrings that only differ in case. The first comparison ignores case and the second comparison considers case.
NEXT : Write a C# Sharp program to compare the last names of two people. It then lists them in alphabetical order.
