LINQ的前pression过滤的FormCollection [英] Linq expression to filter formcollection

问题描述

我有一个的FormCollection，我只是想只能通过按键迭代不包含字符串定价。

I have a FormCollection and I just want to only iterate through the keys the do not contain the string pricing.

那么，我想是这样的...

So what I tried was this...

foreach (var key in collection.AllKeys.Where(k => !k.Contains("Pricing"))){ ... }

问题是回报是不是一个过滤列表中的返回布尔值......在需要字符串过滤列表...

The problem is the return is not a filtered list its returning boolean values... in which in need the filtered list of string...

AllKeys在某种意义上返回一个字符串[]，所以我只是想过滤字符串[这里] ...

AllKeys returns a string[] so in a sense I am just trying to filter a string[] here...

我缺少什么这里...

What I am missing here...
