C# DateTimeOffset.ToUnixTimeSeconds()用法及代码示例


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。

用法: public long ToUnixTimeSeconds ();

返回值:此方法返回自1970-01-01T00:00:00Z以来经过的秒数。


以下示例程序旨在说明DateTimeOffset.ToUnixTimeSeconds()方法的使用:

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
