IfxDb简单用例

IfxConnection connection = new IfxConnection("Database=niosdb;Host=192.168.8.56;Server=niosserver34;Service=8001; UID=informix;Password=informix;");
                string sql = "insert into tap_so_Voronoi(filename,filedata) values(？, ？)";
                IfxCommand cm = new IfxCommand(sql, connection);
                cm.Parameters.Add(new IfxParameter()).Value = scan_start_time;

                cm.Parameters.Add(new IfxParameter()).Value = fileData;
//cm.Parameters.Add(new IfxParameter("filename",IfxType.VarChar,20)).Value = scan_start_time;
                //cm.Parameters.Add(new IfxParameter("filedata",IfxType.Byte)).Value = fileData;

                connection.Open();
                cm.ExecuteNonQuery();
                connection.Close();
