示例1: FileAge
public System.TimeSpan FileAge(long fileCreationTime) {
System.DateTime now = System.DateTime.Now;
try {
System.DateTime fCreationTime =
System.DateTime.FromFileTime(fileCreationTime);
System.TimeSpan fileAge = now.Subtract(fCreationTime);
return fileAge;
}
catch (ArgumentOutOfRangeException) {
// fileCreationTime is not valid, so re-throw the exception.
throw;
}
}示例2: Main
//引入命名空間
using System;
public class Example
{
public static void Main()
{
DateTime date1 = new DateTime(2010, 3, 14, 2, 30, 00);
Console.WriteLine("Invalid Time: {0}",
TimeZoneInfo.Local.IsInvalidTime(date1));
long ft = date1.ToFileTime();
DateTime date2 = DateTime.FromFileTime(ft);
Console.WriteLine("{0} -> {1}", date1, date2);
}
}輸出：
Invalid Time: True 3/14/2010 2:30:00 AM -> 3/14/2010 3:30:00 AM
示例3: Main
//引入命名空間
using System;
class MainClass
{
public static void Main()
{
DateTime myDateTime10 = new DateTime(2004, 1, 15, 23, 2, 5);
long myFileTime = myDateTime10.ToFileTime();
DateTime myDateTime11 = DateTime.FromFileTime(myFileTime);
Console.WriteLine("DateTime.FromFileTime() = " + myDateTime11);
}
}
