DateTimeOffset.FromUnixTimeSeconds(Int64)方法用于将表示从1970-01-01T00:00:00Z开始经过的秒数的Unix时间转换为DateTimeOffset值。

下面的程序说明了DateTimeOffset.FromUnixTimeSeconds(Int64)方法的用法:

范例1:

// C# program to demonstrate the
// DateTimeOffset.FromUnixTimeSeconds(Int64)
// Method
using System;
using System.Globalization;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
        try {
  
            // Converts a Unix time expressed
            // as the number of seconds
            // that have elapsed since 
            // 1970-01-01T00:00:00Z to a 
            // DateTimeOffset value instance 
            // using FromUnixTimeSeconds() method
            DateTimeOffset value = 
               DateTimeOffset.FromUnixTimeSeconds(10000);
  
            // Display the time
            Console.WriteLine("DateTimeOffset is {0}", value);
        }
  
        catch (ArgumentOutOfRangeException e)
        {
            Console.Write("Exception Thrown: ");
            Console.Write("{0}", e.GetType(), e.Message);
        }
    }
}
输出:
DateTimeOffset is 01/01/1970 02:46:40 +00:00

示例2:对于ArgumentOutOfRangeException

// C# program to demonstrate the
// DateTimeOffset.FromUnixTimeSeconds(Int64)
// Method
using System;
using System.Globalization;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
        try {
  
            // Converts a Unix time expressed
            // as the number of seconds
            // that have elapsed since 
            // 1970-01-01T00:00:00Z to a 
            // DateTimeOffset value instance 
            // using FromUnixTimeSeconds() method
            DateTimeOffset value = 
              DateTimeOffset.FromUnixTimeSeconds(254402300799);
  
            // Display the time
            Console.WriteLine("DateTimeOffset is {0}", value);
        }
  
        catch (ArgumentOutOfRangeException e) 
        {
            Console.Write("Exception Thrown: ");
            Console.Write("{0}", e.GetType(), e.Message);
        }
    }
}
输出:
Exception Thrown: System.ArgumentOutOfRangeException
