当偏移psented的UTC时间重新$ P $应用必须是年0到10,000之间。参数名：胶版 [英] The UTC time represented when the offset is applied must be between year 0 and 10,000. Parameter name: offset

问题描述

我在一个ASP.NET MVC3控制器以下code：

I have the following code in an ASP.NET MVC3 Controller:

public PartialViewResult GetCalendar(int? month, int? year)
    {
        var test = new DateTime((year.HasValue ? year.Value : 1), (month.HasValue ? month.Value : 1), 1);
        return PartialView("Calendar", new DateTimeOffset(test));
    }

我的看法型号是的DateTimeOffset？

什么是抛出的异常的原因是什么？

What is the reason for the exception thrown?

推荐答案

的的DateTimeOffset 构造函数首先将任何的DateTime 这是类'UTC'到对应的UTC时间不。然后，它会检查是否UTC-相当于的DateTime 降至 DateTimeOffset.MinValue 的范围和<$ C $之外C> DateTimeOffset.MaxValue ，如果是的话，会抛出一个 ArgumentOutOfRangeException 类似于您所遇到的人。

The DateTimeOffset constructor first converts any DateTime that is not of Kind 'UTC' to the equivalent UTC time. It will then check whether the UTC-equivalent DateTime falls outside of the bounds of DateTimeOffset.MinValue and DateTimeOffset.MaxValue, and if it does, will throw an ArgumentOutOfRangeException similar to the one you are experiencing.

检查 DateTime.Kind 变量测试您正在使用的，如果它不是UTC的，制定出如果转换为UTC将使的DateTime 按规定的测试落在这些范围之外 - 根据MSDN文档中， MINVALUE 和 MaxValue的（在UTC）是1/1/0001 12:00:00 AM +00：00'和'12 /9999分之31下午11:59:59 +00：00。分别为

Check the DateTime.Kind of the variable test that you are using, and if it is not 'UTC', work out if a conversion to UTC will make the DateTime specified by test fall outside of those bounds - according to the MSDN documentation, the MinValue and MaxValue (in UTC) are '1/1/0001 12:00:00 AM +00:00' and '12/31/9999 11:59:59 PM +00:00' respectively.

该文档（<一个href=\"http://msdn.microsoft.com/en-us/library/system.datetimeoffset.minvalue.aspx\">DateTimeOffset.MinValue)注意：

任何的DateTimeOffset值被转换为协调世界时（UTC）的方法执行与MINVALUE比较之前，这意味着一个的DateTimeOffset值，其日期和时间接近最低范围内，但其偏移量为正，可能会引发。一个例外例如，值1/1/0001上午01时00分○○秒+02：00超出范围，因为它比MINVALUE早1小时时，它被转换为UTC

"Any DateTimeOffset value is converted to Coordinated Universal Time (UTC) before the method performs the comparison with MinValue. This means that a DateTimeOffset value whose date and time are close to the minimum range, but whose offset is positive, may throw an exception. For example, the value 1/1/0001 1:00:00 AM +02:00 is out of range because it is one hour earlier than MinValue when it is converted to UTC."

和也（<一href=\"http://msdn.microsoft.com/en-us/library/system.datetimeoffset.maxvalue.aspx\">DateTimeOffset.MaxValue):

任何的DateTimeOffset值被转换为协调通用时间（UTC）之前的方法与MaxValue的进行比较。这意味着一个的DateTimeOffset值，其日期和时间接近最大范围内，但其偏移是负的，可能会引发。例外例如，值12/31/9999 11:00 PM -02：00超出范围，因为它是一个小时比的MaxValue后，当它被转换为UTC

"Any DateTimeOffset value is converted to Coordinated Universal Time (UTC) before the method compares it with MaxValue. This means that a DateTimeOffset value whose date and time are close to the maximum range, but whose offset is negative, may throw an exception. For example, the value 12/31/9999 11:00 PM -02:00 is out of range because it is one hour later than MaxValue when it is converted to UTC."

和按该文档（的DateTimeOffset构造的），则偏移被施加到一个非UTC 类是本地系统的当前时区偏移。

And as per the docs (DateTimeOffset Constructor), the offset that is applied to a non-UTC Kind is the "offset of the local system's current time zone".
