Question

在尝试将Mssql代码转换为MySQL时，特别是在MysqlCommand请求期间，我创建了CS1026，CS1002和CS1513错误代码，这是Mssql代码：

 try
        {
            sqlConnect = new System.Data.SqlClient.SqlConnection("server=" + SQLServerAddress + "," + SQLServerPort + "; initial catalog=" + DatabaseName + "; Integrated Security=SSPI");
            sqlConnect.Open();

            System.Data.SqlClient.SqlCommand sqlCmd = new    System.Data.SqlClient.SqlCommand("SELECT ImageFileName, FacePositionXc,   FacePositionYc, FacePositionW, FacePositionAngle, Eye1X, Eye1Y, Eye2X, Eye2Y, Template, Image, FaceImage FROM FaceList", sqlConnect);

            System.Data.SqlClient.SqlDataReader reader = sqlCmd.ExecuteReader();
            while (reader.Read())

我尝试将其转换为MySQL：

            string conn = "server=localhost; uid=user;" +
            "pwd=password; database=database;";

        MySqlConnection connection = new MySqlConnection(conn);
            connection.Open(); 
        try
        {
            MySqlCommand cmd = connection.CreateCommand();

            cmd.Connection = connection;

            cmd.CommandText = ("SELECT ImageFileName, FacePositionXc, FacePositionYc, FacePositionW, FacePositionAngle, Eye1X, Eye1Y, Eye2X, Eye2Y, Template, Image, FaceImage FROM faces", connection);

            MySqlDataReader reader = cmd.ExecuteReader();
            while (reader.Read())
  {
                TFaceRecord fr = new TFaceRecord();
                fr.ImageFileName = reader.GetString(4);

                fr.FacePosition = new FSDK.TFacePosition();
                fr.FacePosition.xc = reader.GetInt32(5);
                fr.FacePosition.yc = reader.GetInt32(6);
                fr.FacePosition.w = reader.GetInt32(7);
                fr.FacePosition.angle = reader.GetFloat(8);

                fr.FacialFeatures = new FSDK.TPoint[2];
                fr.FacialFeatures[0] = new FSDK.TPoint();
                fr.FacialFeatures[0].x = reader.GetInt32(9);
                fr.FacialFeatures[0].y = reader.GetInt32(10);
                fr.FacialFeatures[1] = new FSDK.TPoint();
                fr.FacialFeatures[1].x = reader.GetInt32(11);
                fr.FacialFeatures[1].y = reader.GetInt32(12);

                fr.Template = new byte[FSDK.TemplateSize];
                reader.GetBytes(9, 0, fr.Template, 0, FSDK.TemplateSize);

                Image img = Image.FromStream(new System.IO.MemoryStream(reader.GetInt32(14)));
                Image img_face = Image.FromStream(new System.IO.MemoryStream(reader.GetInt32(15)));
                fr.image = new FSDK.CImage(img);
                fr.faceImage = new FSDK.CImage(img_face);


                FaceList.Add(fr);

                imageList1.Images.Add(fr.faceImage.ToCLRImage());
                string fn = fr.ImageFileName;
                listView1.Items.Add((imageList1.Images.Count - 1).ToString(), fn.Split('\\')[fn.Split('\\').Length - 1], imageList1.Images.Count - 1);

                textBox1.Text += "File '" + fn + "' read from database\r\n";

                img.Dispose();
                img_face.Dispose();
            }

        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message, "Exception on loading database");
        }
        finally
        {
            if (connection.State == ConnectionState.Open)
            {
                connection.Close();
                // LoadData();
            }
        }
    }

错误是在命令文本末尾生成的。 ＆＃34;，连接）＆＃39;

删除＆＃39;，连接＆＃39;创建一个'无法播放'symbol.Byte []类型的对象以输入'System.Convertable'＆＃39;关于错误异常。

任何人都可以建议使用正确的语法或我的错误感谢你。
