Working With Range

You may want to search a range like between two DateTimes or numbers.

• The Model is same as previous sample:

public class Blog
{
    public string BlogId { get; set; }
    public int CategoryId { get; set; }
    public string Title { get; set; }
    public int Priority { get; set; }
    public bool IsPublished { get; set; }
    public DateTime PublishDate { get; set; }
}

• Just use following Range<T> type in your DTO:

WARNING: Do not use nullable types as generic type parameter in Range<T>. Use same type with your entity. If your property is already nullable in entity, it's ok. Just use same type with model with Range

public class BlogFilterDto : FilterBase<Blog>
{
    public int? CategoryId { get; set; }
    public Range<int> Priority { get; set; } // <-- Careful! Do not use nullable Types as Generic Type parameter
    public string Title { get; set; }
    public bool? IsPublished { get; set; }

    public Range<DateTime> PublishDate { get; set; } // <-- Use Range<DateTime> instead of below
    //public DateTime PublishDate { get; set; }
}

• Now, querystring is changed a little bit. Try following requests:

  • /Blogs?Priority.Min=4
  • /Blogs?Priority.Min=3&Priority.Max=5
  • /Blogs?PublishDate.Max=01.05.2019 // Depends on CultureInfo. If you're using Request Localization, each client must send by its own datetime format
