一个关于ibatis.net的问题，请各位帮帮忙啊~~~~

        public ilist ＥＸＥＣute（string statementname, object parameterobject)
        {
            requestscope scope;
            imappedstatement statement = _mapper.getmappedstatement（statementname);
            parameterproperty property = new parameterproperty（);

            property.propertyname = "name";
            property.columnname = "name";

            if （!this._mapper.issessionstarted)
            {
                this._mapper.openconnection（);
            }

            statement.statement.parametermap.addparameterproperty（property);
            scope = statement.statement.sql.getrequestscope（statement, parameterobject, this._mapper.localsession);
            
            statement.preparedcommand.create（scope, this._mapper.localsession, statement.statement, parameterobject);

            return statement.ＥＸＥＣutequeryforlist（this._mapper.localsession, parameterobject);
        }
