How to describe a custom data type so that EF can properly serialize/deserialize it?

Question

ASP.NET

There is a model like this:

public class Pub
{
   [Key]
   public int Id { get; set; }
   public string Name { get; set; }
   public StringList Items { get; set; } // <--
}

StringList class - contains a Value property that serializes/deserializes it to/from string.

public class StringList
{
   ...
   public string Value
   {
      get { return this.ToString(); }
      set { this.FillFromString(value); }
   }
}

How to explain to EF that when filling the model from the database, you need to set the value to model.Items.Value, and when reading from the model to the database, retrieve the value from model.Items.Value?

Answer 1

try to separate the Model from any logic,
personally in my opinion it would be very good
and convert from / to string / string, entrust someone else, you should not force the model to do this
