DateTimeOffset.ToFileTime方法用於將當前DateTimeOffset對象的值轉換為Windows文件時間。
用法: public long ToFileTime ();
返回值:此方法返回當前DateTimeOffset對象的值,表示為Windows文件時間。
異常:如果生成的文件時間代表了1601年1月1日美國協調世界時(UTC)午夜之前的日期和時間,則此方法將提供ArgumentOutOfRangeException。
以下示例程序旨在說明DateTimeOffset.ToFileTime()方法的使用:
示例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);
}
}
}
輸出:
Windows file time is 128251761000000000
示例2:對於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);
}
}
}
輸出:
Exception Thrown: System.ArgumentOutOfRangeException
