新手请问一个有关问题

新手请教一个问题？
执行“OleDbCommand   objCommand=new   OleDbCommand(strSQL,OleDbConnection)”语句怎么会出这样的错误提示
'System.Data.OleDb.OleDbConnection '   is   a   'type '   but   is   used   like   a   'variable '

[解决办法]
System.Data.OleDb.OleDbConnection conn = new System.Data.OleDb.OleDbConnection();
OleDbCommand objCommand=new OleDbCommand(strSQL,conn)
