DateTimeOffset.ToFileTime() Method in C#
DateTimeOffset.ToFileTime Method is used to convert the value of the current DateTimeOffset object to a Windows file time.
Syntax: public long ToFileTime ();
Return Value: This method returns the value of the current DateTimeOffset object, expressed as a Windows file time.
Exception: This method will give ArgumentOutOfRangeException if the resulting file time would represent a date and time before midnight on January 1, 1601 C.E. Coordinated Universal Time (UTC).
Below programs illustrate the use of DateTimeOffset.ToFileTime() Method:
Example 1:
// C# program to demonstrate the // DateTimeOffset.ToFileTime() // Method using System; using System.Globalization; class GFG { // Main Method public static void Main() { try { // creating object of DateTimeOffset DateTimeOffset offset = new DateTimeOffset(2007, 6, 1, 7, 55, 0, new TimeSpan(-5, 0, 0)); // Converts the value of the current // DateTimeOffset object to a Windows file time. // instance using ToFileTime() method long value = offset.ToFileTime(); // Display the time Console.WriteLine( "Windows file time is {0}" , value); } catch (ArgumentOutOfRangeException e) { Console.Write( "Exception Thrown: " ); Console.Write( "{0}" , e.GetType(), e.Message); } } } |
Output:
Windows file time is 128251761000000000
Example 2: For ArgumentOutOfRangeException
// C# program to demonstrate the // DateTimeOffset.ToFileTime() // Method using System; using System.Globalization; class GFG { // Main Method public static void Main() { try { // creating object of DateTimeOffset DateTimeOffset offset = new DateTimeOffset(1600, 6, 1, 7, 55, 0, new TimeSpan(-5, 0, 0)); // Converts the value of the current // DateTimeOffset object to a Windows file time. // instance using ToFileTime() method long value = offset.ToFileTime(); // Display the time Console.WriteLine( "Windows file time is {0}" , value); } catch (ArgumentOutOfRangeException e) { Console.Write( "Exception Thrown: " ); Console.Write( "{0}" , e.GetType(), e.Message); } } } |
Output:
Exception Thrown: System.ArgumentOutOfRangeException
