C# DateTime.AddMilliseconds()用法及代码示例


此方法用于返回一个新的DateTime,该日期将指定的毫秒数添加到此实例的值。

用法:

public DateTime AddMilliseconds (double value);

在这里,它花费了整数毫秒和分数毫秒。 value参数可以为负或正,并四舍五入为最接近的整数。


返回值:此方法返回一个对象,该对象的值是此实例表示的日期和时间与value表示的毫秒数之和。

异常:如果生成的DateTime小于MinValue或大于MaxValue,则此方法将提供ArgumentOutOfRangeException。

以下示例程序旨在说明DateTime.AddMilliseconds(Double)方法的用法:

示例1:

// C# program to demonstrate the 
// DateTime.AddMilliseconds() Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        try { 
  
            // creating object of DateTime 
            DateTime date1 = new DateTime(2010, 1, 1, 
                                           4, 0, 15); 
  
            // adding the 3000 Milliseconds 
            // using AddMilliseconds() method; 
            DateTime date2 = date1.AddMilliseconds(3000); 
  
            // Display the date1 
            Console.WriteLine("DateTime before operation: "
                           + "{0:hh}:{0:mm}:{0:ss}", date1); 
                                      
  
            // Display the date2 
            Console.WriteLine("\nDateTime after operation: "
                           + "{0:hh}:{0:mm}:{0:ss}", date2); 
                                       
        } 
  
        catch (ArgumentOutOfRangeException e)  
        { 
            Console.Write("Exception Thrown: "); 
            Console.Write("{0}", e.GetType(), e.Message); 
        } 
    } 
}
输出:
DateTime before operation: 04:00:15

DateTime after operation: 04:00:18

示例2:对于ArgumentOutOfRangeException

// C# program to demonstrate the 
// DateTime.AddMilliseconds() Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        try { 
  
            // creating object of DateTime  
            // and initialize with MinValue 
            DateTime date1 = DateTime.MaxValue; 
  
            // Display the date1 
            Console.WriteLine("DateTime before operation: "
                                         + "{0}", date1); 
                                       
  
            // adding the 3000 Milliseconds 
            // using AddHours() method; 
            DateTime date2 = date1.AddHours(3000); 
  
            // Display the date2 
            Console.WriteLine("\nDateTime after operation: "
                           + "{0:hh}:{0:mm}:{0:ss}", date2); 
                                       
        } 
  
        catch (ArgumentOutOfRangeException e)  
        { 
            Console.WriteLine("\nThe resulting DateTime is "+ 
                      "greater than the DateTime.MaxValue "); 
  
            Console.Write("Exception Thrown: "); 
            Console.Write("{0}", e.GetType(), e.Message); 
        } 
    } 
}
输出:
DateTime before operation: 12/31/9999 23:59:59

The resulting DateTime is greater than the DateTime.MaxValue 
Exception Thrown: System.ArgumentOutOfRangeException
