Indlæsning af CSV i MySQL Er dette en fejl? - Fil ikke fundet undtagelse

Nå, jeg fandt endelig ud af svaret. LOAD DATA FILE-sætningen kræver, at filnavnet er en strengværdi, det kan ikke parametreres. Desværre kan MySQLCommand-klassen ikke lide den escapede \ i filstien til et C#-strengobjekt, så den kan ikke finde filen. Jeg fik det til at fungere ved at undslippe flugterne således:

//build the LOAD DATA File command
string working = String.Format("LOAD DATA LOCAL INFILE '{0}' IGNORE ", files.FirstOrDefault().ToString()) +
                         String.Format("INTO TABLE {0} COLUMNS TERMINATED BY ',' LINES TERMINATED BY '\n'", "by_switch")+
                         String.Format(" IGNORE 1 LINES (`Switch`,`Port`,`WWPN`,@the_slot,`Port Index`,@the_time,`Interval`,`Port Send Packet Rate`,")+
                         String.Format("`Port Receive Packet Rate`,`Total Port Packet Rate`,`Port Send Data Rate`,")+        
                         String.Format("`Port Receive Data Rate`,`Total Port Data Rate`,`Port Peak Send Data Rate`,`Port Peak Receive Data Rate`,")+ 
                         String.Format("`Port Send Packet Size`,`Port Receive Packet Size`,`Overall Port Packet Size`,`Error Frame Rate`,")+
                         String.Format("`Dumped Frame Rate`,`Link Failure Rate`,`Loss of Sync Rate`,`Loss of Signal Rate`,`CRC Error Rate`,")+
                         String.Format(" `Short Frame Rate`,`Long Frame Rate`,`Encoding Disparity Error Rate`,")+         
                         String.Format("`Discarded Class3 Frame Rate`,`F-BSY Frame Rate`,`F-RJT Frame Rate`, `Port Send Bandwidth Percentage`,")+
                         String.Format("`Port Receive Bandwidth Percentage`, `Overall Port Bandwidth Percentage`,`Primitive Sequence Protocol Error Rate`,")+
                         String.Format("`Invalid Transmission Word Rate`,`Link Reset Transmitted Rate`,`Link Reset Received Rate`)")+ 
                          String.Format("SET Slot = nullif(@the_slot,''),")+ 
                          String.Format(@"Time= str_to_date(@the_time,'%m/%d/%y %h:%i %p')");


// now escape the escape character
       commandreplaced = commandreplaced.Replace(@"\", @"\\");

   // now execute the command
        MySqlCommand cmd = new MySqlCommand(commandreplaced,sqlconnect);
