C＃中的DateTime.ToBinary()方法

此方法用于将当前DateTime对象序列化为64位二进制值，该值随后可用于重新创建DateTime对象。

Syntax: public long ToBinary ();

Return Value: This method returns a 64-bit signed integer that encodes the Kind and Ticks properties.

下面的程序说明了DateTime.ToBinary()方法的用法

范例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);
    }
}

输出：

64-bit binary value : 634294512150000000

范例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);
    }
}

输出：

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
