时间跨度的配置？

Question

看来ConfigurationElement的TimeSpan无法处理大于23:59:59的值。有没有解决方法？子类TimeSpan，并使新的TimeSpanValidatorAttribute甚至去工作？我需要处理几分钟到几天的时间跨度。

我用下面的配置部分

[ConfigurationProperty("SequenceRolloverDOSCompare", IsRequired = true)] 
[TimeSpanValidator(MinValueString = "0:0:00", MaxValueString = 10675199.02:48:05.4775807", ExcludeRange = false)] 
public TimeSpan SequenceRolloverDOSCompare 
{ 
    get 
    { 
     return (TimeSpan)base["SequenceRolloverDOSCompare"]; 
    } 
} 

与配置看起来像这样：

<SequenceRolloverPolling SequenceRolloverDOSCompare="2:00:00:00" /> 

给ConfigurationErrorsException : The value of the property 'SequenceRolloverDOSCompare' cannot be parsed. The error is: 2:00:00:00 is not a valid value for TimeSpan.

或本：

<SequenceRolloverPolling SequenceRolloverDOSCompare="48:00:00" /> 

给出OverflowException : The TimeSpan could not be parsed because at least one of the hours, minutes, or seconds components is outside its valid range

Answer 1

使用日期和时间之间的.分离器：

<SequenceRolloverPolling 
    SequenceRolloverDOSCompare="2.00:00:00" /> 

TimeSpan format的定义为：

... [ - ] d.hh：MM：SS.FF ，其中可选的负号表示负的时间间隔，d分量是天，hh是24小时制测量的小时，mm是分钟，ss是秒，ff是秒的分数。
