hi to all

this is my code

i am having error like this,

'NHibernate.ISessionFactory' does not contain a definition for 'ConnectionProvider' and no extension method 'ConnectionProvider' accepting a first argument of type 'NHibernate.ISessionFactory' could be found (are you missing a using directive or an assembly reference?)

C#

public void ClearDatabase()
        {
            // Initialize
            SqlConnection connection = m_SessionFactory.ConnectionProvider.GetConnection() as SqlConnection;
            SqlCommand command = null;
            string[] dataTables = new string[] { "OrderItems", "Products", "Orders", "Customers" };
            string sql = null;

            // Delete all records from all tables
            using (connection)
            {
                // Iterate tables
                for (int i = 0; i < dataTables.Length; i++)
                {
                    // Build query and command, and execute
                    sql = String.Format("Delete from {0}", dataTables[i]);
                    command = new SqlCommand(sql, connection);
                    command.ExecuteNonQuery();
                }
            }
        }

Solution 1

As quoted in the URL[^]

"You will also need to cast the SessionFactory to the concrete implementation (NHibernate.Impl.SessionFactoryImpl) in order to access the ConnectionProvider property (at least in NH v3)"

If you using multiple database then you have to give seperate session-factory.
your error says that there is no connection provider.

so, just check your nhibernate.cfg.xml (for availability of connection provider)
refer below config file code (and change config file according to that).

XML

<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2-x-factories">

    <session-factory name="Development">
        <property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>
        <property name="dialect">NHibernate.Dialect.MsSql2008Dialect</property>
        <property name="connection.driver_class">NHibernate.Driver.SqlClientDriver</property>
        <property name="connection.connection_string">Server=Sql01;DataBase=dbABC1;uid=A;pwd=A123</property>

        <property name="show_sql">true</property>

        <mapping assembly="DataLayer" />
    </session-factory>

    <session-factory name="Production">
        <property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>
        <property name="dialect">NHibernate.Dialect.MsSql2008Dialect</property>
        <property name="connection.driver_class">NHibernate.Driver.SqlClientDriver</property>
        <property name="connection.connection_string">Server=Sql02;DataBase=dbABC2;uid=A1;pwd=A1234</property>

        <property name="show_sql">false</property>

        <mapping assembly="DataLayer" />
    </session-factory>

</hibernate-configuration>

Solution 2

Are you using dependency injection? Please check if you have configured it correctly in your config file.
