Question

I have a class User.

I have created a generic CSV exporter that works on any type IEnumerable. It checks the class and exports all of its properties.

In the class User i dont want some of the properties to export (like password etc).

I know there is a mapper of some kind that allows to create a temp class and define the properties from the original class… i cant seem to find any exaple.

regards !

If you want to project an IEnumerable<User> (let’s call it userList) to a new IEnumerable with only some of the properties:

var query = userList.Select(u => new { u.Name, u.Address, u.Phone });

Now query will be an IEnumerable<'a> (anonymous type) which only contains the Name, Address and Phone properties from your User objects.
