How to Convert Lowercase to String in C#?

In programming, uppercase letters have different ASCII values than their lowercase counterparts. Therefore, converting a lowercase letter to uppercase involves subtracting a specific value from its ASCII code. In C# the process is very simple when we use the built-in methods.

using System;

class Program
{
    static void Main(string[] args)
    {
        // Input lowercase string
        string lowercaseStr "hello, techiehook!";

        // Convert to uppercase
        string uppercaseStr = lowercaseString.ToUpper();

        // Output the result
        Console.WriteLine("Lowercase string: " + lowercaseStr);
        Console.WriteLine("Uppercase string: " + uppercaseStr);
    }
}

In this program, we have declared a lowercase string "hello, techiehook!". Then, we used the ToUpper() method, which is a built-in function in C# for strings. This method converts all characters in the string to uppercase.

Output:

Lowercase string: hello, techiehook!
Uppercase string: HELLO, TECHIEHOOK!
