📜  C#中的TimeSpan.FromDays()方法

📅  最后修改于: 2021-05-29 22:04:22             🧑  作者: Mango

此方法用于获取表示指定天数的TimeSpan,精确到最接近的毫秒。

例外情况:

  • OverflowException :当给定的double值小于最小可能值或大于最大可能值,或者该值是PositiveInfinity或NegativeInfinity时,将发生OverflowException。
  • ArgumentException:如果值为NaN。

下面的程序说明了TimeSpan.FromDays(Double)Method的用法:

程序1:

// C# program to demonstrate the
// TimeSpan.FromDays(Double) Method
using System;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
        try {
  
            TimeSpan interval = TimeSpan.FromDays(43.999999);
            Console.WriteLine("The Timespan is : {0}",
                                            interval);
        }
  
        catch (OverflowException e) 
       {
            Console.Write("Exception Thrown: ");
            Console.Write("{0}", e.GetType(), e.Message);
        }
    }
}
输出:
The Timespan is : 43.23:59:59.9140000

程序2:对于溢出异常

// C# program to demonstrate the
// TimeSpan.FromDays(Double) Method
using System;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
        try {
  
            TimeSpan interval = 
                TimeSpan.FromDays(Double.NegativeInfinity);
  
            Console.WriteLine("The Timespan is : {0}",
                                            interval);
        }
  
        catch (OverflowException e) 
        {
            Console.Write("Exception Thrown: ");
            Console.Write("{0}", e.GetType(), e.Message);
        }
    }
}
输出:
Exception Thrown: System.OverflowException
