C#中的DateTime.Equals()方法
使用C#中的DateTime.Equals()方法检查两个DateTime对象或实例是否相等。如果两者相等，则返回TRUE，否则返回FALSE。
语法
以下是语法-
public static bool Equals (DateTime date1, DateTime date2);
示例
现在让我们看一个实现DateTime.Equals()方法的示例-
using System;
public class Demo {
public static void Main() {
DateTime d1 = new DateTime(2019, 09, 10, 5, 15, 25);
DateTime d2 = d1.AddMonths(25);
Console.WriteLine("Initial DateTime = {0:dd} {0:y}, {0:hh}:{0:mm}:{0:ss} ", d1);
Console.WriteLine("\nNew DateTime (After adding months) = {0:dd} {0:y}, {0:hh}:{0:mm}:{0:ss} ", d2);
bool res = DateTime.Equals(d1, d2);
if (res)
Console.WriteLine("\ndate1 = date2. ");
else
Console.WriteLine("\ndate1 is not equal to date2. ");
}
}输出结果
这将产生以下输出-
Initial DateTime = 10 September 2019, 05:15:25 New DateTime (After adding months) = 10 October 2021, 05:15:25 date1 is not equal to date2.
示例
现在让我们来看另一个实现DateTime.Equals()方法的示例-
using System;
public class Demo {
public static void Main() {
DateTime d1 = new DateTime(2019, 11, 11, 7, 15, 30);
DateTime d2 = new DateTime(2019, 11, 11, 7, 15, 30);
Console.WriteLine("DateTime1 = {0:dd} {0:y}, {0:hh}:{0:mm}:{0:ss} ", d1);
Console.WriteLine("\nDateTime2 = {0:dd} {0:y}, {0:hh}:{0:mm}:{0:ss} ", d2);
bool res = DateTime.Equals(d1, d2);
if (res)
Console.WriteLine("\ndate1 = date2 ");
else
Console.WriteLine("\ndate1 is not equal to date2 ");
}
}输出结果
这将产生以下输出-
DateTime1 = 10 September 2019, 05:15:25 DateTime2 = 10 September 2019, 05:15:25 date1 = date2
