推荐答案

您尚未设置命令对象的连接属性.

you have not set the connection property of the command object.

类似这样的东西.

System.Data.OleDb. OleDbCommand o = 新建 System.Data.OleDb. OleDbCommand () ;

System.Data.OleDb.OleDbCommand o = new System.Data.OleDb.OleDbCommand();

//o.Connection////将您创建的连接设置为命令的连接属性

// o.Connection  // set the connection that u have created to the connection property of your command

对象.

希望这会有所帮助.

此致
