C#中的DateTime.AddSeconds()方法
C#中的DateTime.AddSeconds()方法用于将指定的秒数添加到此实例的值。这将返回一个新的DateTime。
语法
以下是语法-
public DateTime AddSeconds (double sec);
在这里，秒是要添加的秒数。如果要减去秒，则设置一个负值。
示例
现在让我们看一个实现DateTime.AddSeconds()方法的示例-
using System;
public class Demo {
public static void Main(){
DateTime d1 = new DateTime(2019, 10, 25, 6, 20, 40);
DateTime d2 = d1.AddSeconds(25);
System.Console.WriteLine("Initial DateTime = {0:dd} {0:y}, {0:hh}:{0:mm}:{0:ss} ", d1);
System.Console.WriteLine("\nNew DateTime (After adding seconds) = {0:dd} {0:y}, {0:hh}:{0:mm}:{0:ss} ", d2);
}
}输出结果
这将产生以下输出-
Initial DateTime = 25 October 2019, 06:20:40 New DateTime (After adding seconds) = 25 October 2019, 06:21:05
示例
现在让我们来看另一个实现DateTime.AddSeconds()方法的示例-
using System;
public class Demo {
public static void Main(){
DateTime d1 = new DateTime(2019, 10, 25, 6, 20, 40);
DateTime d2 = d1.AddSeconds(-10);
System.Console.WriteLine("Initial DateTime = {0:dd} {0:y}, {0:hh}:{0:mm}:{0:ss} ", d1);
System.Console.WriteLine("\nNew DateTime (After subtracting seconds) = {0:dd} {0:y}, {0:hh}:{0:mm}:{0:ss} ", d2);
}
}输出结果
这将产生以下输出-
Initial DateTime = 25 October 2019, 06:20:40 New DateTime (After subtracting seconds) = 25 October 2019, 06:20:30
