C#中的DateTime.AddHours()方法
C#中的DateTime.AddHours()方法用于将指定的小时数添加到此实例的值。此方法返回一个新的DateTime。
语法
以下是语法-
public DateTime AddHours (double hrs);
上面的小时数是要添加的小时数。该值可以是负数以减去小时数。
示例
现在让我们看一个实现DateTime.AddHours()方法的示例
using System;
public class Demo {
public static void Main(){
DateTime d1 = new DateTime(2019, 11, 2, 9, 0, 10);
DateTime d2 = d1.AddHours(2);
System.Console.WriteLine("Initial DateTime = {0:dd} {0:y}, {0:t} ", d1);
System.Console.WriteLine("\nNew DateTime (After adding hours) = {0:dd} {0:y}, {0:t} ", d2);
}
}输出结果
这将产生以下输出-
Initial DateTime = 02 November 2019, 9:00 AM New DateTime (After adding hours) = 02 November 2019, 11:00 AM
示例
现在让我们来看另一个实现DateTime.AddHours()方法的示例-
using System;
public class Demo {
public static void Main(){
DateTime d1 = new DateTime(2019, 10, 5, 9, 0, 10);
DateTime d2 = d1.AddHours(-5);
System.Console.WriteLine("Initial DateTime = {0:dd} {0:y}, {0:t} ", d1);
System.Console.WriteLine("\nNew DateTime (After subtracting hours) = {0:dd} {0:y}, {0:t} ", d2);
}
}输出结果
这将产生以下输出-
Initial DateTime = 05 October 2019, 9:00 AM New DateTime (After subtracting hours) = 05 October 2019, 4:00 AM
