{
    class Max_of_Numbers
    {
        static void Main(string[] args)
        {
           Console.WriteLine(" Int Number Max: " +  Math.Max(3,4));
           Console.WriteLine(" Double Number Max: " + Math.Max(3.333, 4.444));
           Console.WriteLine(" Long Number Max: " + Math.Max(3L, 4L));
           Console.WriteLine(" Decimal Number Max: " + Math.Max(3.33M, 4.44M));

Calculate Truncated Number from a Decimal Number in C#

If you want to truncate a given decimal number of double number, C# provide a function Math.Truncate() to return corresponding number.

The below code provide sample demo application for the same.

C# Example Code to truncate a given number:

using System;

namespace DemoConsoleApplication
{
    class Math_Truncate
    {
        static void Main(string[] args)
        {
            decimal dec_Number = 400.2222M;

            decimal Result = Math.Truncate(dec_Number);
            Console.WriteLine(" Truncated Number: " + Result);

            Console.ReadLine();
        }
    }
}

How to execute batch files in Hidden Mode using C#

using System.Diagnostics;

namespace DemoConsoleApplication
{

    class Batch_File
    {
        static void Main(string[] args)
        {
            ProcessStartInfo PI = new ProcessStartInfo("c:\\Test_File.bat");
            PI.WindowStyle = ProcessWindowStyle.Hidden;
            Process BP = new Process();
            BP.StartInfo = PI;
            BP.Start();      

            Console.ReadLine();
        }
    }

{

    class Exit_Loop
    {
        static void Main(string[] args)
        {
            for (int i = 0; i < 10; i++)
            {
                Console.WriteLine("Number #:" + i.ToString());
                if (i == 5)
                    break;
