I am a beginner,
Program of the client and the server can be connected, here is only part of the program, the other part of database operations,
I think this part of the procedure is the primary key of the database table, but I don't have any solution, turned to everyone a great god,
Public class roles
{
Public virtual int Id {set; The get; }//primary keys
Public virtual string Name {set; The get; }
Public virtual int Level {set; The get; }
Public virtual bool IsMan {set; The get; }
Public virtual string RolePrefabName {set; The get; }
Public virtual Users User {set; The get; }//foreign key
}

The class RoleMap: ClassMap
{
Public RoleMap ()
{
Id (x=& gt; X.I d). The Column (" Id ");//primary keys
The Map (x=& gt; X.N ame). The Column (" name ");
The Map (x=& gt; X.L evel). The Column (" level ");
The Map (x=& gt; X.I sMan). The Column (" isman ");
The Map (x=& gt; X.R olePrefabName). The Column (" roleprefabname ");
The References (x=& gt; X.U ser.) the Column (" userid ");//foreign key
The Table (" role ");
}
}
Public class RoleManager
{

{

Transaction.Com MIT ();
The Info (" res RowCount ()="+ res. RowCount ());
Return (List) Res. List (a);//error
}
}
}

Public void AddRole (Role Role)
{
Log. The Info (role. The Name + "/" + role. Level + "/" + role. IsMan + "/" + role. RolePrefabName + "/" + role. The User. The UserName);

}
}

break;
}
The response. The Parameters=the Parameters;

return response;
