方法的调用规则

静态方法只能通过类名打点调用，不用使用new来动态调用！如AdminControl.AdminUpdate

new ControlEntityAdminControl().AdminUpdate()无法使用

public static bool AdminUpdate(string adminId, string username, string truename) { string cmdText = "UPDATE dbo.TB_Admin SET UserName=@username,TrueNam=@truename WHERE ID=@AdminId"; SqlParameter[] parameters = { new SqlParameter("@username",SqlDbType.VarChar,100){Value=username}, new SqlParameter("@truename",SqlDbType.VarChar,32){Value=truename}, new SqlParameter("@adminId",SqlDbType.VarChar,32){Value=adminId} }; int rs = SqlHelper.ExecuteNonQuery(cmdText, parameters); return rs > 0; }
