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
