How do you implement filtering and sorting with EF Core?

Mid ASP.NET Web API
Quick Answer Filtering with EF Core: apply Where() predicates that translate to SQL WHERE clauses. Sorting: OrderBy(x => x.Name).ThenBy(x => x.Id). Dynamic sorting: use reflection or a library like System.Linq.Dynamic.Core to build expressions from string sort fields. Always validate sort field names against allowed values to prevent injection. Apply pagination after filtering and sorting.

Answer

Use LINQ:

  • Where() for filtering
  • OrderBy()/OrderByDescending() for sorting
  • Skip()/Take() for pagination
