Last Updated :

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:
csharp
using System;
using System.Globalization;
class GFG {
public static void Main()
{
try {
DateTime date1 = new DateTime(2010, 3, 14, 2, 30, 00);
DateTime date2 = DateTime.FromFileTime(2500000000000);
System.Console.WriteLine("DateTime before "
+ "operation: {0:y} {0:dd}", date1);
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);
}
}
}
|
Output:
DateTime before operation: 2010 March 14
DateTime after operation: 1601 January 03
Example 2: For ArgumentOutOfRangeException
csharp
using System;
using System.Globalization;
class GFG {
public static void Main()
{
try {
DateTime date1 = new DateTime(2010, 3,
14, 2, 30, 00);
DateTime date2 = DateTime.FromFileTime(-1);
System.Console.WriteLine("DateTime before "
+ "operation: {0:y} {0:dd}",date1);
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);
}
}
}
|
Output:
fileTime is less than 0
Exception Thrown: System.ArgumentOutOfRangeException
