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
