C#: String representation of a date and time to its DateTime equivalent

C# Sharp DateTime: Exercise-42 with Solution

Write a C# Sharp program to convert the specified string representation of a date and time to its DateTime equivalent. This is done using the specified format, culture-specific format information, and style.

Sample Solution:-

C# Sharp Code:

using System;
using System.Globalization;

public class Example42
{
   public static void Main()
   {
      string dateString;
      CultureInfo culture;
      DateTimeStyles styles;
      DateTime dateResult;

      // Parse a date and time with no styles.
      dateString = "05/06/2016 10:00 AM";
      culture = CultureInfo.CreateSpecificCulture("de-DE");
      styles = DateTimeStyles.None;
      if (DateTime.TryParse(dateString, culture, styles, out dateResult))
         Console.WriteLine("{0} converted to {1} {2}.", 
                           dateString, dateResult, dateResult.Kind);
      else
         Console.WriteLine("Unable to convert {0} to a date and time.", 
                           dateString);

      // Parse the same date and time with the AssumeLocal style.
      styles = DateTimeStyles.AssumeLocal;
      if (DateTime.TryParse(dateString, culture, styles, out dateResult))
         Console.WriteLine("{0} converted to {1} {2}.", 
                           dateString, dateResult, dateResult.Kind);
      else
         Console.WriteLine("Unable to convert {0} to a date and time.", dateString);

      // Parse a date and time that is assumed to be local.
      // This time is five hours behind UTC. The local system's time zone is 
      // eight hours behind UTC.
      dateString = "2016/05/06T10:00:00-5:00";
      styles = DateTimeStyles.AssumeLocal;
      if (DateTime.TryParse(dateString, culture, styles, out dateResult))
         Console.WriteLine("{0} converted to {1} {2}.", 
                           dateString, dateResult, dateResult.Kind);
      else
         Console.WriteLine("Unable to convert {0} to a date and time.", dateString);

      // Attempt to convert a string in improper ISO 8601 format.
      dateString = "05/06/2016T10:00:00-5:00";
      if (DateTime.TryParse(dateString, culture, styles, out dateResult))
         Console.WriteLine("{0} converted to {1} {2}.", 
                           dateString, dateResult, dateResult.Kind);
      else
         Console.WriteLine("Unable to convert {0} to a date and time.", dateString);

      // Assume a date and time string formatted for the fr-BE culture is the local 
      // time and convert it to UTC.
      dateString = "2015-05-06 10:00";
      culture = CultureInfo.CreateSpecificCulture("fr-BE");
      styles = DateTimeStyles.AdjustToUniversal | DateTimeStyles.AssumeLocal;
      if (DateTime.TryParse(dateString, culture, styles, out dateResult))
         Console.WriteLine("{0} converted to {1} {2}.", 
                           dateString, dateResult, dateResult.Kind);
      else
         Console.WriteLine("Unable to convert {0} to a date and time.", dateString);

   }
}

Sample Output:

05/06/2016 10:00 AM converted to 6/5/2016 10:00:00 AM Unspecified.                                            
05/06/2016 10:00 AM converted to 6/5/2016 10:00:00 AM Local.                                                  
2016/05/06T10:00:00-5:00 converted to 5/6/2016 8:30:00 PM Local.                                              
Unable to convert 05/06/2016T10:00:00-5:00 to a date and time.                                                
2015-05-06 10:00 converted to 5/6/2015 4:30:00 AM Utc.
