FileReadString not reading thefile

MQL Language
#1

my mt5 script is very simple, it read csv like this :slight_smile:

void OnStart()
  {
//---
   string dt ;
   int file_20 = FileOpen("104782531.csv", FILE_READ|FILE_CSV,';');
      if (file_20!=-1)
       Print("Error is",GetLastError());
   Print(StringToInteger(FileReadString(file_20)));
   FileClose(file_20);

  }

it print value 0 .

I don’t know why this not working same as mt4.

my csv file only contain 1 line :

275117161;GBPNZD;1;0.03;0;0;;0;1568327929;1.91565;0.64191;-290;-8.71;-297;151368.44;0;-8.92

int file_20 = FileOpen("104782531.csv", FILE_READ|FILE_CSV|FILE_ANSI,';');
