日期时间。C# 中的 ToBinary()方法
原文:https://www . geesforgeks . org/datetime-tobinary-method-in-c-sharp/
此方法用于将当前日期时间对象序列化为 64 位二进制值,该值随后可用于重新创建日期时间对象。
语法:public long ToBinary();
返回值:此方法返回一个 64 位有符号整数,用于编码“种类”和“刻度”属性。
以下程序说明了日期时间的使用。ToBinary() 方法
例 1:
// C# program to demonstrate the
// DateTime.ToBinary()
// Method
using System;
using System.Globalization;
class GFG {
// Main Method
public static void Main()
{
// creating object of DateTime
DateTime date = new DateTime(2011, 1,
1, 4, 0, 15);
// Serializes the current DateTime
// object to a 64-bit binary value
// using ToBinary() method;
long value = date.ToBinary();
// Display the value
Console.WriteLine("64-bit binary value : {0}",
value);
}
}
Output:
64-bit binary value : 634294512150000000
例 2:
// C# program to demonstrate the
// DateTime.ToBinary()
// 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)
{
// Serializes the current DateTime
// object to a 64-bit binary value
// using ToBinary() method;
long value = date.ToBinary();
// Display the value
Console.WriteLine("64-bit binary value"+
" of {0} is {1}", date, value);
}
}
Output:
64-bit binary value of 01/03/2010 04:00:15 is 633980880150000000
64-bit binary value of 01/05/2010 04:00:15 is 633982608150000000
