C#: Converts current DateTime object to UTC

C# Sharp DateTime: Exercise-40 with Solution

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

Sample Solution:-

C# Sharp Code:

using System;

class Example40
{
    static void Main()
    {
        // Declare variables to store local and universal DateTime values.
        DateTime localDateTime, univDateTime;

        // Prompt the user to enter a date and time.
        Console.WriteLine("Enter a date and time.");
        string strDateTime = Console.ReadLine();

        try {
            // Attempt to parse the entered string to a local DateTime.
            localDateTime = DateTime.Parse(strDateTime);
            // Convert the local DateTime to its equivalent Universal Time.
            univDateTime = localDateTime.ToUniversalTime();

            // Display the local and converted universal times.
            Console.WriteLine("{0} local time is {1} universal time.",
                                localDateTime,
                                univDateTime);
        }
        catch (FormatException) {
            // Catch a FormatException if the input string is not in a valid DateTime format.
            Console.WriteLine("Invalid format.");
            return;
        }

        // Prompt the user to enter a date and time in universal time.
        Console.WriteLine("Enter a date and time in universal time.");
        strDateTime = Console.ReadLine();

        try {
            // Attempt to parse the entered string to a universal DateTime.
            univDateTime = DateTime.Parse(strDateTime);
            // Convert the universal DateTime to its equivalent Local Time.
            localDateTime = univDateTime.ToLocalTime();

            // Display the universal and converted local times.
            Console.WriteLine("{0} universal time is {1} local time.",
                                     univDateTime,
                                     localDateTime);
        }
        catch (FormatException) {
            // Catch a FormatException if the input string is not in a valid DateTime format.
            Console.WriteLine("Invalid format.");
            return;
        }

    }
}

Sample Output:

Enter a date and time.                                                                                        
06/12/2017 02:20                                                                                              
6/12/2017 2:20:00 AM local time is 6/11/2017 8:50:00 PM universal time.                                       
Enter a date and time in universal time.                                                                      
06/12/2017 2:30                                                                                               
6/12/2017 2:30:00 AM universal time is 6/12/2017 8:00:00 AM local time.
