Create filter model

first, you need to specify for what type of array you are trying to filter

    [FilterFor(typeof(T))] //Where T is the type/class of array element

in the filter model, every property should have FilterMethod attribute, which specifies details for filtering array

    [FilterMethod(FilterMethods.Contains, propertyName)]

sample of filter model

    [FilterFor(typeof(Product))]
    public class ProductFilterModel : BaseFilter
    {
        [FilterMethod(FilterMethods.Contains, nameof(Product.Caption))]
        public List<string> Captions { get; set; }

        [FilterMethod(FilterMethods.Equal)]
        public decimal? Price { get; set; }

        [FilterMethod(FilterMethods.GreaterThanOrEqual, nameof(Product.ReceiveDate))]
        public DateTime? ReceiveDateFrom { get; set; }
    }
