无法从C＃中的MS Access数据库中读取

Question

这是我的代码，我已将此功能放在我的案例中，为什么我仍然无法从MS Access数据库中检索任何数据？是数据库问题吗？或者因为我的MS Access是版本2013，这是一个盗版版本？

public void display(event_detail e)
{
    string path = Directory.GetCurrentDirectory();
    string connstring = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + path + @"\GameMuseumManagementSystem.mdb";

    OleDbConnection conn = new OleDbConnection(connstring); //Create connection
    conn.Open();

    OleDbCommand cmd = new OleDbCommand("SELECT * from Event  WHERE Event_Title ='" + PassName + "'", conn); //Create command

    cmd.Connection = conn; //command connect to database

    OleDbDataReader myReader = cmd.ExecuteReader();

    while (myReader.Read())
    {
        e.notxt.Text = (myReader["Event_No"].ToString());
        //e.notxt.ReadOnly = true;
        e.titletxt.Text = (myReader["Event_Name"].ToString());
        //e.titletxt.ReadOnly = true;
        e.datedetail.Text = (myReader["Event_Date"].ToString());
        //e.datedetail.ReadOnly = true;
        e.detailtxt.Text = (myReader["Event_detail"].ToString());
        //e.detailtxt.ReadOnly = true;
    }
}
