DateTimeOffset.ToString Method

Converts the value of the current DateTimeOffset object to its equivalent string representation.

Namespace:  System
Assemblies:   System.Runtime (in System.Runtime.dll)
  mscorlib (in mscorlib.dll)

public override string ToString()

Return Value

Type: System.String
A string representation of a DateTimeOffset object that includes the offset appended at the end of the string.

ExceptionCondition
ArgumentOutOfRangeException

The date and time is outside the range of dates supported by the calendar used by the current culture.

The return value of this method is identical to that of the DateTime.ToString() method, except that it includes a space followed by the offset appended at the end of the string. In other words, it formats output using the short date pattern, the long time pattern, and the zzz custom format string, with each element separated from the previous element by a space. For example, if DateTime.ToString() returns a value of 1/12/2008 6:15:50 PM, ToString() returns a value of 1/12/2008 6:15:50 PM -08:00 for a time that is eight hours behind Coordinated Universal Time (UTC).

This method uses formatting information derived from the current culture. For more information, see CurrentCulture. Other overloads of the ToString method enable you to specify the culture whose formatting to use, and to define the output pattern of the DateTimeOffset value.

Notes to Callers

The ToString() method returns the string representation of the date and time in the calendar used by the current culture. If the value of the current DateTimeOffset instance is earlier than Calendar.MinSupportedDateTime or later than Calendar.MaxSupportedDateTime, the method throws an ArgumentOutOfRangeException. The following example provides an illustration. It attempts to format a date that is outside the range of the HijriCalendar class when the current culture is Arabic (Syria).

using System;
using System.Globalization;
using System.Threading;

public class Example
{
   public static void Main()
   {
      DateTimeOffset date1 = new DateTimeOffset(new DateTime(550, 1, 1),
                                                TimeSpan.Zero);
      CultureInfo dft;
      CultureInfo arSY = new CultureInfo("ar-SY");
      arSY.DateTimeFormat.Calendar = new HijriCalendar();

      // Change current culture to ar-SY.
      dft = Thread.CurrentThread.CurrentCulture;
      Thread.CurrentThread.CurrentCulture = arSY;

      // Display the date using the current culture's calendar.             
      try {
         Console.WriteLine(date1.ToString());
      }
      catch (ArgumentOutOfRangeException) {
         Console.WriteLine("{0} is earlier than {1} or later than {2}", 
                           date1.ToString("d", CultureInfo.InvariantCulture), 
                           arSY.DateTimeFormat.Calendar.MinSupportedDateTime.ToString("d", CultureInfo.InvariantCulture),  
                           arSY.DateTimeFormat.Calendar.MaxSupportedDateTime.ToString("d", CultureInfo.InvariantCulture)); 
      }

      // Restore the default culture.
      Thread.CurrentThread.CurrentCulture = dft;
   }
}
// The example displays the following output: 
//    01/01/0550 is earlier than 07/18/0622 or later than 12/31/9999

The following example illustrates calls to the ToString() method and displays its output on a system whose current culture is en-us.

DateTimeOffset thisDate;

// Show output for UTC time
thisDate = DateTimeOffset.UtcNow;
Console.WriteLine(thisDate.ToString());  // Displays 3/28/2007 7:13:50 PM +00:00 

// Show output for local time 
thisDate = DateTimeOffset.Now;
Console.WriteLine(thisDate.ToString());  // Displays 3/28/2007 12:13:50 PM -07:00 

// Show output for arbitrary time offset
thisDate = thisDate.ToOffset(new TimeSpan(-5, 0, 0));
Console.WriteLine(thisDate.ToString());  // Displays 3/28/2007 2:13:50 PM -05:00
