C# DateTimeOffset.ToOffset()用法及代码示例


DateTimeOffset.ToOffset(TimeSpan)方法用于将当前DateTimeOffset对象的值转换为由偏移值指定的日期和时间。

用法: public DateTimeOffset ToOffset (TimeSpan offset);
Here, it takes the offset to convert the DateTimeOffset value to.

返回值:此方法返回一个与原始DateTimeOffset对象相等的对象(即,它们的ToUniversalTime()方法返回相同的时间点),但其Offset属性设置为offset。


异常:

  • ArgumentException如果生成的DateTimeOffset对象的DateTime值早于MinValue。或者生成的DateTimeOffset对象的DateTime值晚于MaxValue。
  • ArgumentOutOfRangeException如果偏移量小于-14小时。或偏移量大于14小时。

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

示例1:

// C# program to demonstrate the 
// DateTimeOffset.ToOffset(TimeSpan) 
// Method 
using System; 
using System.Globalization; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        try { 
  
            // creating object of  DateTimeOffset 
            DateTimeOffset offset = new DateTimeOffset(2007, 
                    6, 1, 7, 55, 0, new TimeSpan(-5, 0, 0)); 
  
            // Converts the value of  
            // the current DateTimeOffset 
            // object to the date and time  
            // specified by an offset value. 
            // instance using ToOffset() method 
            DateTimeOffset value = offset.ToOffset(new TimeSpan(-5, 1, 0)); 
  
            // Display the time 
            Console.WriteLine("DateTimeOffset is {0}", value); 
        } 
  
        catch (ArgumentOutOfRangeException e)  
        { 
            Console.Write("Exception Thrown: "); 
            Console.Write("{0}", e.GetType(), e.Message); 
        } 
  
        catch (ArgumentException e)  
        { 
            Console.Write("Exception Thrown: "); 
            Console.Write("{0}", e.GetType(), e.Message); 
        } 
    } 
}
输出:
DateTimeOffset is 06/01/2007 07:56:00 -04:59

示例2:对于ArgumentOutOfRangeException

// C# program to demonstrate the 
// DateTimeOffset.ToOffset(TimeSpan) 
// Method 
using System; 
using System.Globalization; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        try { 
  
            // creating object of  DateTimeOffset 
            DateTimeOffset offset = DateTimeOffset.MaxValue; 
  
            // Converts the value of the 
            // current DateTimeOffset 
            // object to the date and time  
            // specified by an offset value. 
            // instance using ToOffset() method 
            DateTimeOffset value = offset.ToOffset(new TimeSpan(5, 1, 0)); 
  
            // Display the time 
            Console.WriteLine("DateTimeOffset is {0}", value); 
        } 
  
        catch (ArgumentOutOfRangeException e)  
        { 
            Console.Write("Exception Thrown: "); 
            Console.Write("{0}", e.GetType(), e.Message); 
        } 
  
        catch (ArgumentException e)  
        { 
            Console.Write("Exception Thrown: "); 
            Console.Write("{0}", e.GetType(), e.Message); 
        } 
    } 
}
输出:
Exception Thrown: System.ArgumentOutOfRangeException
