C#中的DateTime.Subtract()方法
C#中的DateTime.Subtract()方法用于减去指定的DateTime或跨度。
语法
以下是语法-
public TimeSpan Subtract (DateTime value); public DateTime Subtract (TimeSpan value);
示例
现在让我们看一个实现DateTime.Subtract()方法的示例-
using System;
public class Demo {
public static void Main() {
DateTime d1 = new DateTime(2019, 10, 10, 8, 10, 40);
DateTime d2 = new DateTime(2017, 11, 06, 8, 10, 40);
Console.WriteLine("Date 1 = "+d1);
Console.WriteLine("Date 2 = "+d2);
TimeSpan res = d1.Subtract(d2);
Console.WriteLine("TimeSpan between two dates = {0} ",res);
}
}输出结果
这将产生以下输出-
Date 1 = 10/10/2019 8:10:40 AM Date 2 = 11/6/2017 8:10:40 AM TimeSpan between two dates = 703.00:00:00
示例
现在让我们来看另一个实现DateTime.Subtract()方法的示例-
using System;
public class Demo {
public static void Main() {
DateTime d = new DateTime(2019, 10, 10, 8, 10, 40);
TimeSpan t = new TimeSpan(1, 10, 10, 12);
Console.WriteLine("Date = "+d);
DateTime res = d.Subtract(t);
Console.WriteLine("DateTime between date d and timespan t = {0} ",res);
}
}输出结果
这将产生以下输出-
Date = 10/10/2019 8:10:40 AM DateTime between date d and timespan t = 10/8/2019 10:00:28 PM
