Customers_Filter方法中的Lambda表达式 [英] Lambda Expression in Customers_Filter method

问题描述

我有一个相当复杂的业务场景，必须根据明确的业务规则将客户过滤到用户.

I have a rather complicated business scenario where I have to filter the Customers to the users according to intrincated business rules.

我已经定义了一个函数，该函数将获取一个Customer Entity，并返回一个布尔值作为结果，然后尝试将它在Customer_Filter方法中用作lambda表达式.

I have defined a Function that gets one Customer Entity and returns a Boolean value as a result and then tried to use it in the Customers_Filter method as a lambda expression.

但是该功能被完全忽略了.

But the Function is totally ignored.

问题:

1.可以在Customers_Filter方法内调用用户定义的函数吗?

1. Is possible to call user defined functions inside the Customers_Filter method?

2.我该如何实现这种功能?

2. How must I implement this kind of function?
