私は奇妙な行動を経験しています。私の web.api は、GET 要求で ObjectCollection から隠しフィールドのみを返しています。これは私のコントローラーです：
// GET: api/UserDocuments
[Route("api/UserDocuments/User/{userName}")]
public List<DocIndex> Get(string userName)
{
User usuari = Humanisme.User.LoadByUserName(userName);
List<DocIndex> resposta = DocumentCollection.LoadIndexPerUsuari(usuari);
return resposta;
}
BOM から生成されるオブジェクトは次のとおりです。
namespace Humanisme
{
using CodeFluent.Runtime;
using CodeFluent.Runtime.Utilities;

web.api get メソッドを呼び出すと、次の JSON が返されます。

シリアライザー (WebApiConfig.cs から)
