Select anonymous object with calculated tax e.Name, Tax = e.Salary * 0.1 });?

Short answer: var taxed = employees.Select(e => new { var taxed = employees.Select(e => new { var taxed = employees.Select(e => new { var taxed = employees.Select(e => new { var taxed = employees.Select(e => new { var taxed = employees.Select(e => new { var taxed = employees.Select(e => new { var taxed = employees.Select(e => new {

Example code

var taxed = employees.Select(e => new { var taxed = employees.Select(e => new { var taxed = employees.Select(e => new { var taxed = employees.Select(e => new { var taxed = employees.Select(e => new { var taxed = employees.Select(e => new { var taxed = employees.Select(e => new { var taxed = employees.Select(e => new {

Real-world example (ShopNest)

ShopNest maps entities to DTOs with .Select(o => new OrderSummaryDto { Id = o.Id, Total = o.Total }) so the API does not leak internal fields.
