此方法用於返回一個新的DateTime,該日期將指定的毫秒數添加到此實例的值。
用法:
public DateTime AddMilliseconds (double value);
在這裏,它花費了整數毫秒和分數毫秒。 value參數可以為負或正,並四舍五入為最接近的整數。
返回值:此方法返回一個對象,該對象的值是此實例表示的日期和時間與value表示的毫秒數之和。
異常:如果生成的DateTime小於MinValue或大於MaxValue,則此方法將提供ArgumentOutOfRangeException。
以下示例程序旨在說明DateTime.AddMilliseconds(Double)方法的用法:
示例1:
// C# program to demonstrate the
// DateTime.AddMilliseconds() Method
using System;
class GFG {
// Main Method
public static void Main()
{
try {
// creating object of DateTime
DateTime date1 = new DateTime(2010, 1, 1,
4, 0, 15);
// adding the 3000 Milliseconds
// using AddMilliseconds() method;
DateTime date2 = date1.AddMilliseconds(3000);
// Display the date1
Console.WriteLine("DateTime before operation: "
+ "{0:hh}:{0:mm}:{0:ss}", date1);
// Display the date2
Console.WriteLine("\nDateTime after operation: "
+ "{0:hh}:{0:mm}:{0:ss}", date2);
}
catch (ArgumentOutOfRangeException e)
{
Console.Write("Exception Thrown: ");
Console.Write("{0}", e.GetType(), e.Message);
}
}
}
輸出:
DateTime before operation: 04:00:15 DateTime after operation: 04:00:18
示例2:對於ArgumentOutOfRangeException
// C# program to demonstrate the
// DateTime.AddMilliseconds() Method
using System;
class GFG {
// Main Method
public static void Main()
{
try {
// creating object of DateTime
// and initialize with MinValue
DateTime date1 = DateTime.MaxValue;
// Display the date1
Console.WriteLine("DateTime before operation: "
+ "{0}", date1);
// adding the 3000 Milliseconds
// using AddHours() method;
DateTime date2 = date1.AddHours(3000);
// Display the date2
Console.WriteLine("\nDateTime after operation: "
+ "{0:hh}:{0:mm}:{0:ss}", date2);
}
catch (ArgumentOutOfRangeException e)
{
Console.WriteLine("\nThe resulting DateTime is "+
"greater than the DateTime.MaxValue ");
Console.Write("Exception Thrown: ");
Console.Write("{0}", e.GetType(), e.Message);
}
}
}
輸出:
DateTime before operation: 12/31/9999 23:59:59 The resulting DateTime is greater than the DateTime.MaxValue Exception Thrown: System.ArgumentOutOfRangeException
