Write a C# Sharp program to convert the value of the current DateTime object to Coordinated Universal Time (UTC)

using System;

class Example40
{
	static void Main()
	{
		DateTime localDateTime, univDateTime;

		Console.WriteLine("Enter a date and time.");
		string strDateTime = Console.ReadLine();

		try {
			localDateTime = DateTime.Parse(strDateTime);
    		univDateTime = localDateTime.ToUniversalTime();

    		Console.WriteLine("{0} local time is {1} universal time.",
   								localDateTime,
    								univDateTime); 
		}
		catch (FormatException) {
			Console.WriteLine("Invalid format.");
			return;
		}

		Console.WriteLine("Enter a date and time in universal time.");
		strDateTime = Console.ReadLine();

		try {
			univDateTime = DateTime.Parse(strDateTime);
    		localDateTime = univDateTime.ToLocalTime();

    		Console.WriteLine("{0} universal time is {1} local time.",
    								 univDateTime,
    								 localDateTime); 
		}
		catch (FormatException) {
			Console.WriteLine("Invalid format.");
			return;
		}
