注解

值 minutes 将添加到指定的 DateTime中。 如果 minutes 为负数，则生成的 DateTime 早于指定的 DateTime。

如果生成的 DateTime 时间超出指定 DateTime的日期，则生成的日期部分将受到影响。 如果生成的 DateTime 日期在指定 DateTime的月份之外，则结果的月份部分将受到影响。 如果生成的月份在指定 DateTime的年份之外，则结果DateTime的年份部分将受到影响。 如果生成的 DateTime 年份在指定 DateTime的纪元之外，则生成的 纪元部分将受到影响。

Kind返回DateTime值的 属性始终等于 DateTimeKind.Unspecified。 可以通过调用 DateTime.SpecifyKind 方法保留 Kind 参数的 time 属性，如以下示例所示。

returnTime = DateTime.SpecifyKind(cal.AddMinutes(time, minutes), time.Kind);

returnTime = DateTime.SpecifyKind(cal.AddMinutes(time, minutes), time.Kind)
