**I have a application in C#, but this application will be integrated with a ERP in Delphi.

if i return a WebMethod Directly with a Entity Collection, results cannot be able to use, return a DataSet null...**

[WebMethod] publicEntityCollection<VitrineMarcasEntity> ListarMarcas() { VitrineMarcasManager vitrineMarcasManager = newVitrineMarcasManager(null); EntityCollection<VitrineMarcasEntity> marcas = vitrineMarcasManager.GetList(0); return marcas; }

One person here can take me a help?

Suggestions?

Convert Entity in a DataTable? Return Dictionaries?

Please help-me with this problem.?

Hi Igor, Why not serialize the entities and return that. You can _WriteXml _with _Compact25 _(it's compact, you just need the structured info right? ) and then consume it at your consumer app.

Take a look at Serialization Support section on the manual

Ok, but, i will return a string with the xml? Because in the other side, i dont have the LLBLGen Installed.

This Xml Generated is in W3C Pattern? Because the Delphi Web Service Client and the ASP.NET Web Service use this Pattern, consuming will be very simple and easy.

I don't know Delphi, this part of implementation will be done by another company (Creator of the Application in Delphi).

Did you makes a code sample to me to the Service side using your solution?

Thanks for all and sorry by my english... i'm from brazil..

at http://llblgen.com/pages/examples.aspx look for the WCF examples.

The best solution is Convert EntityCollection to a DataTable... But the Xml Generated not is valid to the DataTable... Suggestions? ** DataTable ret = new DataTable();

string xmlCompact25; marcas.WriteXml(XmlFormatAspect.Compact25 | XmlFormatAspect.DatesInXmlDataType | XmlFormatAspect.MLTextInCDataBlocks, out xmlCompact25);

marcas.WriteXml(out xmlCompact25; ret.ReadXml(xmlCompact25);

return ret**

Thanks for all!
