Dynamic IQueryable extensions created by Hepsiburada developers.

Hepsi.Extensions v0.1

We have started to share our commonly used extensions for C#. For now, dynamic filtering and ordering is available.

Sorting and filtering by property name was a shameful process if the property is ambiguous at runtime.

DynamicOrderBy

• IQueryable DynamicOrderBy(this IQueryable source, string propertyName, string direction)
• IQueryable DynamicOrderBy(this IQueryable source, OrderByRequest orderByRequest)

:(

        public IQueryable<DummyDocument> SortDocuments(IQueryable<DummyDocument> documents, string propertyName)
        {
            switch (propertyName.ToLower())
            {
                case "createdat":
                    return documents.OrderBy(d => d.CreatedAt);
                case "count":
                    return documents.OrderBy(d => d.Count);
                case "id":
                    return documents.OrderBy(d => d.Id);
                case "name":
                    return documents.OrderBy(d => d.Name);
                case "complexype.dummyinteger":
                    return documents.OrderBy(d => d.ComplexType.DummyInteger);
                case "complexype.innercomplextype.dummyinteger":
                    return documents.OrderBy(d => d.ComplexType.InnerComplexType.DummyInnerInteger);

                //Can be hundred cases?... :(

                default:
                    //Can't find the property
                    return documents;
            }
        }

Cool Way

        public IQueryable<DummyDocument> SortDocuments(IQueryable<DummyDocument> documents, string propertyName)
        {
            return documents.DynamicOrderBy(propertyName, "ascending");
        }
        
        //Or you can use our OrderByRequest type as an alternative:
        
        public IQueryable<DummyDocument> SortDocuments(IQueryable<DummyDocument> documents, string propertyName)
        {        
            return documents.DynamicOrderBy(new OrderByRequest(propertyName, OrderByDirection.Ascending));
        }

DynamicFilterBy

• IQueryable DynamicFiltering(this IQueryable source, string propertyName, string value)

:(

        public IQueryable<DummyDocument> FilterDocuments(IQueryable<DummyDocument> documents, string propertyName, string value)
        {
            switch (propertyName.ToLower())
            {
                case "count":
                    return documents.Where(d => d.Count == Int32.Parse(value));
                case "id":
                    return documents.Where(d => d.Id == Int32.Parse(value));
                case "name":
                    return documents.Where(d => d.Name == value);

                //Can be hundred cases?... :(

                default:
                    //Can't find the property
                    return documents;
            }
        }

Cool Way

        public IQueryable<DummyDocument> FilterDocuments(IQueryable<DummyDocument> documents, string propertyName, string value)
        {
            return documents.DynamicFiltering(propertyName, value);
        }

Note: Dynamic Filtering does not support complex types for now.
