Example 1: csharp


 // C# program to demonstrate
// Byte.ToString(IFormatProvider)
// Method
using System;
using System.Globalization;

class GFG {

    // Main Method
    public static void Main()
    {
        // declaring and initializing bytevalue
        byte byteValue = 15;

        // creating and initializing 
        // the object of CultureInfo
        CultureInfo provider = new CultureInfo("en-us");

        // getting the value
        // using ToString()
        string value = byteValue.ToString(provider);

        // Display the value
