Expression Composer

And

Example And

Expression<Func<Item, bool>> sample = f => f.Id == 1;
sample = sample.And(f => f.Name == "name");

result:

((f.Id == 1) AndAlso (f.Name == "name"))

Or

Expression<Func<Item, bool>> sample = f => f.Id == 1;
sample = sample.Or(f => f.Name == "name");

result:

((f.Id == 1) OrElse (f.Name == "name"))

Order By Expression By Property Name

using Ardalis.Specification;
using Azka.Extensions;

namespace AzkaUnitTest;

public sealed class ItemSpecification : Specification<Item>
{
    public ItemSpecification(string orderByProperty = nameof(Item.Id), OrderType orderType = OrderType.Ascending)
    {
        if (orderType == OrderType.Ascending)
        {
            Query.OrderBy(orderByProperty);
        }
        else
        {
            Query.OrderByDescending(orderByProperty);
        }
