DateTime.FromFileTime(Int64) Method is used to converts the specified Windows file time to an equivalent local time.
Syntax: public static DateTime FromFileTime (long fileTime);
Here, it takes a Windows file time expressed in ticks.Return Value: This method returns an object that represents the local time equivalent of the date and time represented by the fileTime parameter.
Exception: This method will give ArgumentOutOfRangeException if the fileTime is less than 0 or represents a time greater than MaxValue.
Below programs illustrate the use of DateTime.FromFileTime(Int64) Method:
Example 1:
// C# program to demonstrate the // DateTime.FromFileTime(Int64) Method using System; using System.Globalization; class GFG { // Main Method public static void Main() { try { // creating object of DateTime DateTime date1 = new DateTime(2010, 3, 14, 2, 30, 00); // converting 2500000000000 file // time represented in ticks // into DateTime format // using FromBinary() method DateTime date2 = DateTime.FromFileTime(2500000000000); // Display the date1 System.Console.WriteLine( "DateTime before " + "operation: {0:y} {0:dd}" , date1); // Display the date2 System.Console.WriteLine( "\nDateTime after" + " operation: {0:y} {0:dd}" , date2); } catch (ArgumentOutOfRangeException e) { Console.Write( "Exception Thrown: " ); Console.Write( "{0}" , e.GetType(), e.Message); } } } |
DateTime before operation: 2010 March 14 DateTime after operation: 1601 January 03
Example 2: For ArgumentOutOfRangeException
// C# program to demonstrate the // DateTime.FromFileTime() Method using System; using System.Globalization; class GFG { // Main Method public static void Main() { try { // creating object of DateTime DateTime date1 = new DateTime(2010, 3, 14, 2, 30, 00); // converting -1 file time // represented in ticks // into DateTime format // using FromBinary() method DateTime date2 = DateTime.FromFileTime(-1); // Display the date1 System.Console.WriteLine( "DateTime before " + "operation: {0:y} {0:dd}" ,date1); // Display the date2 System.Console.WriteLine( "\nDateTime after" + " operation: {0:y} {0:dd}" , date2); } catch (ArgumentOutOfRangeException e) { Console.WriteLine( "fileTime is less than 0 " ); Console.Write( "Exception Thrown: " ); Console.Write( "{0}" , e.GetType(), e.Message); } } } |
fileTime is less than 0 Exception Thrown: System.ArgumentOutOfRangeException
