C# DateTimeOffset.AddDays()用法及代码示例


此方法用于返回一个新的DateTimeOffset对象,该对象将指定天数的整数和小数天加到该实例的值上。

用法: public DateTimeOffset AddDays (double days);
Here, it takes a number of whole and fractional days.

返回值:此方法返回一个对象,该对象的值是当前DateTimeOffset对象表示的日期和时间与天数表示的天数之和。


异常:如果结果DateTimeOffset的值小于MinValue或结果DateTimeOffset的值大于MaxValue,则此方法将提供ArgumentOutOfRangeException。

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

示例1:

// C# program to demonstrate the 
// DateTimeOffset.AddDays(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)); 
  
            // adding a specified number of whole  
            // and fractional days to the value  
            // of this instance using AddDays(Double)  
            // method 
            DateTimeOffset value = offset.AddDays(10); 
  
            // 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 06/11/2007 07:55:00 -05:00

示例2:对于ArgumentOutOfRangeException

// C# program to demonstrate the 
// DateTimeOffset.AddDays(Double) 
// Method 
using System; 
using System.Globalization; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        try { 
  
            // creating object of  DateTimeOffset 
            DateTimeOffset offset = DateTimeOffset.MaxValue; 
  
            // adding a specified number of whole and 
            // fractional days to the value of this instance. 
            // using AddDays(Double) method; 
            DateTimeOffset value = offset.AddDays(10); 
  
            // 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
