This method is used to convert the value of the current DateTime object to a Windows file time.
Syntax: public long ToFileTime ();
Return Value: This method returns the value of the current DateTime 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 12:00 midnight January 1, 1601 C.E. UTC.
Below programs illustrate the use of DateTime.ToFileTime() Method:
Example 1:
// C# program to demonstrate the // DateTime.ToFileTime() // Method using System;
using System.Globalization;
class GFG {
// Main Method
public static void Main()
{
try {
// creating object of DateTime
DateTime date = new DateTime(2011, 1,
1, 4, 0, 15);
// converting current DateTime
// object to a Windows file time.
// using ToFileTime() method;
long value = date.ToFileTime();
// Display the TimeSpan
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 129383280150000000
Example 2: For ArgumentOutOfRangeException
// C# program to demonstrate the // DateTime.ToFileTime() // Method using System;
using System.Globalization;
class GFG {
// Main Method
public static void Main()
{
try {
// creating object of DateTime
DateTime date = new DateTime(1600, 1,
1, 4, 0, 15);
// converting current DateTime
// object to a Windows file time.
// using ToFileTime() method;
long value = date.ToFileTime();
// Display the TimeSpan
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
