C# DateTimeOffset.AddMonths()用法及代码示例

此方法用于返回一个新的DateTimeOffset对象，该对象将指定的月份数添加到当前实例的值中。

用法： public DateTimeOffset AddMonths (int months);

Here, it takes a number of whole months. The number can be negative or positive.

返回值：此方法返回一个对象，其值是当前DateTimeOffset对象表示的日期和时间与月份表示的月数之和。

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.AddMonths(Int32)方法的用法：

示例1:

// C# program to demonstrate the 
// DateTimeOffset.AddMonths(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 months to the value of this 
            // instance using AddMonths() method 
            DateTimeOffset value = offset.AddMonths(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 04/01/2008 07:55:00 -05:00

示例2:对于ArgumentOutOfRangeException

// C# program to demonstrate the 
// DateTimeOffset.AddMonths(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 months to the value of this 
            // instance using AddMonths() method 
            DateTimeOffset value = offset.AddMonths(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
