C# DateTimeOffset.AddMilliseconds()用法及代码示例


此方法用于获取新的DateTimeOffset对象,该对象将指定的毫秒数添加到当前实例的值。

用法: public DateTimeOffset AddMilliseconds (double milliseconds);
Here, it takes a number of whole and fractional milliseconds. The number can be negative or positive.

返回值:此方法返回一个对象,该对象的值是当前DateTimeOffset对象所表示的日期和时间与毫秒所表示的整数(毫秒)之和。


异常:如果所得的DateTimeOffset值小于MinValue或大于MaxValue,则此方法将提供ArgumentOutOfRangeException。

以下示例程序旨在说明DateTimeOffset.AddMilliseconds(Double)方法的用法:

示例1:

// C# program to demonstrate the 
// DateTimeOffset.AddMilliseconds(Double) 
// 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)); 
  
            // a number of whole and fractional milliseconds 
            // instance using AddMilliseconds() method 
            DateTimeOffset value = offset.AddMilliseconds(2000); 
  
            // Display the time 
            Console.WriteLine("DateTimeOffset is {0}", value); 
        } 
  
        catch (ArgumentOutOfRangeException e) { 
            Console.Write("Exception Thrown: "); 
            Console.Write("{0}", e.GetType(), e.Message); 
        } 
    } 
}
输出:
DateTimeOffset is 06/01/2007 07:55:02 -05:00

示例2:对于ArgumentOutOfRangeException

// C# program to demonstrate the 
// DateTimeOffset.AddMilliseconds(Double) 
// Method 
using System; 
using System.Globalization; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        try { 
  
            // creating object of  DateTimeOffset 
            DateTimeOffset offset = DateTimeOffset.MaxValue; 
  
            // a number of whole and fractional milliseconds 
            // instance using AddMilliseconds() method 
            DateTimeOffset value = offset.AddMilliseconds(2000); 
  
            // Display the time 
            Console.WriteLine("DateTimeOffset is {0}", value); 
        } 
  
        catch (ArgumentOutOfRangeException e) { 
            Console.Write("Exception Thrown: "); 
            Console.Write("{0}", e.GetType(), e.Message); 
        } 
    } 
}
输出:
Exception Thrown: System.ArgumentOutOfRangeException
