日期时间。C# 中的 GetHashCode()方法
原文:https://www . geesforgeks . org/datetime-gethashcode-method-in-c-sharp/
此方法用于返回此实例的哈希代码。
语法:public override int GetHashCode()；
返回值:这个方法返回一个 32 位有符号整数哈希码。
以下程序说明了日期时间的使用。GetHashCode() 方法:
例 1:
// C# program to demonstrate the
// DateTime.GetHashCode()
// Method
using System;
class GFG {
// Main Method
public static void Main()
{
// creating object of DateTime
DateTime date = new DateTime(2010, 1,
1, 4, 0, 15);
// getting hashcode from DateTime
// using GetHashCode() method;
int value = date.GetHashCode();
// Display the hashcode
Console.WriteLine("hashcode is {0}", value);
}
}
Output:
hashcode is 103491886
例 2:
// C# program to demonstrate the
// DateTime.GetHashCode()
// Method
using System;
class GFG {
// Main Method
public static void Main()
{
// calling check() method
check(new DateTime(2010, 1,
3, 4, 0, 15));
check(new DateTime(2010, 1,
5, 4, 0, 15));
}
public static void check(DateTime date)
{
// getting HashCode from DateTime
// using GetHashCode() method;
int value = date.GetHashCode();
// Display the ShortTime
Console.WriteLine("HashCode of {0} is {1}",
date, value);
}
}
Output:
HashCode of 01/03/2010 04:00:15 is 1802939328
HashCode of 01/05/2010 04:00:15 is -1337841070
