Sorting

Sorting is easy to implement. You filter object just should inherit from OrderableFilterBase. After you inherit, OrderableFilterBase applies query and sorting when you call ApplyFilter method.

Showcase

[HttpGet]
public IActionResult Get([FromQuery]BookFilter filter)
{
    var result = db.Books.ApplyFilter(filter).ToList();
    return Ok(result);
}

Implementation

You just need to create a Filter object that includes properties which is able to filter.

public class BookFilter : OrderableFilterBase // <-- Just inherit OrderableFilterBase 
{
    public string Title { get; set; }
    public string Author { get; set; }
    public int? Year { get; set; }
    // ...
}

Usage

Now your querystring has 2 more parameter. sort and sortBy.

• /books?sort=Title
• /books?sort=Title&sortBy=Ascending
• /books?sort=Title&sortBy=Descending
