帮助asp.net mvc反射和属性

I need a way to dynamically populate this query... to avoid repeating the same query which I will have to do about 20 times

我需要一种方法来动态填充这个查询……为了避免重复相同的查询，我需要重复20次

public decimal percentage_of_property(string property)
{
    var total = Routines().Where(r=>r.property==true).Count();
    return (decimal)100 * total / routines_total();
}

This obviously doesn't work... but I put it there so you can see what I'm trying to achieve...

这显然是行不通的…但是我把它放在那里，这样你就能看到我想要达到的目标。

Thanks in advance.

提前谢谢。

Assuming Routine is the type you can avoid reflection and use functional programming like so:-

假设例程是您可以避免反射和使用函数式编程的类型:-。

public decimal percentage_of_property(Func<Routine, bool> propertyTest)
{
    var total = Routines().Where(r => propertyTest(r)).Count();
    return (decimal)100 * total / routines_total();
}

use it like:-

使用它:-

percentage_of_property(r => r.propertyName)
