ColumnAttribute.Storage property does not work as expected

    public class EncryptedString
    {
        private string _str= "Encrypted";
        [Column(Storage = "_str")]
        public string Str { get { return "Decrypted"; } set { _str = "Encrypted"; } }
    }

The idea here is to save encrypted string to DB and decrypt it when using inside the code. Bit it does not work

db.Insert(new EncryptedString());

inserts “Decrypted”, so storage is not used.

Also, when I query

db.Strings.Where(g => g.Str == "Decrypted")

It queries on “Decrypted” string, not “Encrypted”

Is it a bug? If not, how do I make it work?

What about:

public class EncryptedString
{
    public string Encrypted;
    public string Value { get {return Decrypt(Encrypted); } set {Encrypted = Encrypt(value); } }
}

public MyEntity 
{
    public EncryptedString Value {get;set;}
}

MappigSchema.SetConvertExpression<EncryptedString, DataParameter>(s => return new DataParameter() { Value = s.Encrypted });
MappigSchema.SetConvertExpression<string, EncryptedString>(s => return new EncryptedString() { Value = s});

this should work

Speaking about your suggestion, i think yes we should implement also read usage for storage.
