DateTimeOffset.ToUnixTimeSeconds方法用于返回自1970-01-01T00:00:00Z以来经过的秒数。在返回Unix时间之前,此方法会将当前实例转换为UTC。而且,它将为1970-01-01T00:00:00Z之前的日期和时间值返回负值。

下面的程序说明了DateTimeOffset.ToUnixTimeSeconds()方法的用法:

范例1:

// C# program to demonstrate the
// DateTimeOffset.ToUnixTimeMilliseconds()
// Method
using System;
using System.Globalization;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
        // creating object of  DateTimeOffset
        DateTimeOffset offset = new DateTimeOffset(2017,
                6, 1, 7, 55, 0, new TimeSpan(-5, 0, 0));
  
        // Returns the number of seconds
        // that have elapsed since 1970-01-01T00:00:00Z.
        // instance using ToUnixTimeSeconds() method
        long value = offset.ToUnixTimeSeconds();
  
        // Display the time
        Console.WriteLine("Returns the number of"+
                         " seconds : {0}", value);
    }
}
输出:
Returns the number of seconds : 1496321700

范例2:

// C# program to demonstrate the
// DateTimeOffset.ToUnixTimeSeconds()
// Method
using System;
using System.Globalization;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
        // creating object of  DateTimeOffset
        DateTimeOffset offset = new DateTimeOffset(2017,
                6, 1, 7, 55, 0, new TimeSpan(-5, 0, 0));
  
        // Returns the number of seconds
        // that have elapsed since 1970-01-01T00:00:00Z.
        // instance using ToUnixTimeSeconds() method
        long value = offset.ToUnixTimeSeconds();
  
        // Display the time
        Console.WriteLine("Returns the number of"+
                         " seconds : {0}", value);
    }
}
输出:
Returns the number of seconds : 1496321700
