nhibernate で簡単なアプリケーションを作成します: class utilisateur.hbm.xml
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" auto-import="true">
<class name="nhiber.utilisateur, nhiber" table="utilisateur">
<id name="login" type="string"></id>
<property name="password" type="string" />
<property name="age" type="int" />
<property name="location" type="string" />
<property name="name" type="string" />
</class>
</hibernate-mapping>

public virtual IList<utilisateur> get_liste_utilisateurs(){
using (ISession session = OpenSession())

IList<utilisateur> pets = query.List<utilisateur>();
return pets;

}
public static ISessionFactory SessionFactory;

config.AddAssembly(Assembly.GetCallingAssembly());
SessionFactory = config.BuildSessionFactory();

しかし、私はこの例外を持っています: System.InvalidOperationException: Échec d'instance. à System.Data.SqlClient.TdsParser.Connect(ServerInfo serverInfo, SqlInternalConnectionTds connHandler, Boolean ignoreSniOpenTimeout, Int64 timerExpire, Boolean encrypt, Boolean trustServerCert, Boolean integratedSecurity) à nhiber.utilisateur.OpenSession() dans C:\Users\HP\documents\ Visual Studio 2010\Projects\nhiber\utilisateur.cs:ligne 32 à nhiber.utilisateur.get_liste_utilisateurs() および C:\Users\HP\documents\visual studio 2010\Projects\nhiber\utilisateur.cs:ligne 19 à nhiber.Form1 ..ctor() dans C:\Users\HP\documents\visual studio 2010\Projects\nhiber\Form1.cs:ligne 21
助けが必要です。何かアドバイスはありますか?
