How do I perform a dynamic select in Linq?

Question

I am trying to figure out how to dynamically specify the properties for my select clause in a linq query.

Lets say I have a collection of employee objects. At run time, the end user will be specifying which properties they would like to see for those employees, so I need to be able to dynamically construct my Linq select clause.

I have used the dynamic Linq library, but I prefer not to use that, because it requires me to build a string to pass to the select method. I'd like to understand how to do this via Expressions.

Answer 1

Check out Scott Gu's Blog.

It will explain exactly how to do it.

Answer 2

This looks like something that fits more with your requirements of not using dynamic linq.
