Question

我试图通过以下约束使用发票日期计算到期日期

将有两个文本框，一个是输入当月的日期，另一个是输入截止日期前一天
如果月份的日期是4，而截止日期的前一天是5，我们必须通过减去4和5来计算值，如果减去的值是-ve 1并且输入的发票日期是11/13 / 2016所以截止日期必须是2017年4月12日（这里是04月份的日期）
如果当月的日期为15，而截止日期为前一天为5且减去的值为10（非负数），则输入的发票日期为2016年11月13日，表示截止日期必须为12/15 / 2016（此处15是月中的某一天）如果发票日期小于或等于减去的值，即10，如发票日期11/09/2016，那么发票日期必须是2016年11月15日

请注意，在计算星期日时，上述约束也必须满足闰年

请帮我修新SQL服务器

最后通过创建以下功能解决了这个问题

BackgroundTaskBuilder builder = new BackgroundTaskBuilder()
{
    Name = "myTask"
};
builder.SetTrigger(new ToastNotificationActionTrigger());
BackgroundTaskRegistration task = builder.Register();

在使用SQL Server函数计算截止日期时需要帮助
