Example

The following example demonstrates the ParseExact method.


// ww w.j a v a2  s . c o  m
using System;
using System.Globalization;

public class Example
{
   public static void Main()
   {
      string dateString, format;  
      DateTime result;
      CultureInfo provider = CultureInfo.InvariantCulture;

      // Parse date-only value with invariant culture.
      dateString = "06/15/2008";
      format = "d";
      try {
         result = DateTime.ParseExact(dateString, format, provider);
         Console.WriteLine("{0} converts to {1}.", dateString, result.ToString());
      }
      catch (FormatException) {
         Console.WriteLine("{0} is not in the correct format.", dateString);
      } 
      dateString = "6/15/2008";
      try {
         result = DateTime.ParseExact(dateString, format, provider);
         Console.WriteLine("{0} converts to {1}.", dateString, result.ToString());
      }
      catch (FormatException) {
         Console.WriteLine("{0} is not in the correct format.", dateString);
      }

      // Parse date and time with custom specifier.
      dateString = "Sun 15 Jun 2008 8:30 AM -06:00";
      format = "ddd dd MMM yyyy h:mm tt zzz";
      try {
         result = DateTime.ParseExact(dateString, format, provider);
         Console.WriteLine("{0} converts to {1}.", dateString, result.ToString());
      }
      catch (FormatException) {
         Console.WriteLine("{0} is not in the correct format.", dateString);
      }
      dateString = "Sun 15 Jun 2008 8:30 AM -06";
      try {
         result = DateTime.ParseExact(dateString, format, provider);
         Console.WriteLine("{0} converts to {1}.", dateString, result.ToString());
      }   
      catch (FormatException) {
         Console.WriteLine("{0} is not in the correct format.", dateString);
      } 
      dateString = "15/06/2008 08:30";
      format = "g";
      provider = new CultureInfo("fr-FR");
      try {
         result = DateTime.ParseExact(dateString, format, provider);
         Console.WriteLine("{0} converts to {1}.", dateString, result.ToString());
      }   
      catch (FormatException) {
         Console.WriteLine("{0} is not in the correct format.", dateString);
      } 

   }
}

The code above generates the following result.
