can you please provide a VB .NET sample for localization with DataObjects.NET? I tried to convert C# sample in the manual, but I found it difficult; can't translate this part

[Field] // This is a storage of all localizations for Page class public LocalizationSet<pagelocalization> Localizations { get; private set; }

because in VB there aren't auto-implemented properties


so I don't know:

  • how to correctly manage the Get part of the property; I have to write it explicitly
  • how to initialize correctly LocalizationSet(of T); I don't know which parameters to use in Public Sub New(owner As Xtensive.Orm.Entity, field As Xtensive.Orm.Model.FieldInfo); I think that owner = my entity, but what about FieldInfo?

Hi Tommaso Gobbato.

I thing you can't do it. If we have C# interface which have property like this

interface SomeInterface
  String SomeTextProperty { get; }

then C# allows implement additional setter, but not VB.Net In VB.Net implementation of properties like this must be ReadOnly. DataObjects.Net initializes that property by itself and uses internal mechanisms for creating instanses. Even if you initialize it in constructor, Dataobjects can't reinitialize it later.

Hi Alexey,

thank you for reply; I supposed I can't do it, needed just a confirmation; it's a pity, I'm evaluating some .NET ORM products for my company, and data localization is a very important feature for our needs; so it would be it great to have it directly without too much self-coding. Do you think that it could be implemented in next versions of DataObjects.NET for VB.NET too, or the limit of the language is too difficult / impossible to bypass?

Of course a workaround can be to write entity classes in C# in a separate project and other parts of application in VB, anyway I'm going on with evaluation of the product

Other great features would be:

  • a visual designer, to design entities quicker and easier
  • T4-style code generation (as for example in Telerik DataAccess or DevArt LinqConnect), to easily generate POCO classes and converters beetween them and entities
