推荐答案

试试这个

Try this

cmd = new OleDbCommand(query, cn); 
        cn.Open();
        OleDbDataReader reader = cmd.ExecuteReader(); 
        while (reader.Read())
        {
            name =  reader.GetString(0);
            pass = reader.GetString(1);
        }

看看：

OleDbCommand Class [ ^ ]



那里你会找到关于你正在使用的课程的完整文档，以及一些如何实际使用它的例子。



祝你好运。

Have a look at that:
OleDbCommand Class[^]

There you will find a complete documentation on the class you are using, as well as some examples on how to actually use it.

Good luck.
