            connection.ConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=G:\schoolwork\Year 11\SDD\3 SINGLE TASK\SDD Single Project - Michael \SDD Single Project - Michael \bin\Persondata.accdb;

            this.Hide(); //hides this page
            MainScreen frm = new MainScreen(); //finds the next screen (the main game)
            frm.Show(); //shows it
        }

        private void btnShow_Click(object sender, EventArgs e)
        {
            try
            {
                connection.Open(); //opens connection 
                OleDbCommand command = new OleDbCommand(); //declare our object of oleDB command
                command.Connection =  connection; // the connection is giving to the command
                string query = "select * Persondata";
                command.CommandText = query; // pass the query to the command

                OleDbDataAdapter da = new OleDbDataAdapter(command);
                DataTable dt = new DataTable();
                da.Fill(dt); // the error supposedly occurs here!!
                dataGridView1.DataSource =  dt;


                connection.Close(); // closes the connection
            }
            catch (Exception ex)
            {
                MessageBox.Show("Error " + ex);
            }
        }


    }
}

当我试着运行这个程序时，我得到的错误代码是，在第46行的“*Persondata”处有语法错误（这是theda.Fill（dt）；行），我无法理解它。请帮助其完成作业。

此：

"select * Persondata"

一定是

"select * FROM Persondata"

请发布实际错误消息您的查询没有“from”关键字，它应该是“select*from Persondata”。另外，如果我是正确的，您正在从MS Access文件读取数据-尝试将表名放入[]（[Persondata]）。我非常确定这会引发异常，并且我非常确定异常已经在确切地告诉您出了什么问题。。。
