Disadvantages of this class
this code is not very fast
handles only handle Unicode files at the moment. Single byte files are not a development priority.
It is possible this code reads a line and notices that EOF is reached at the end of the line.If possible do not test with IsEnding(), use the return value of the ReadLine functions instead. The return value will only return FILE_STATE_EOF after the next read. So all records will be processed. Using the samples
I provided a LibreCalc spreadsheet with 3 sheets. It is a sample that calculate some orders of a pyramid system. The first sheet as exported as CSV file with "Save As...". Use format CSV file with Tab as separator and to use Unicode. Put the CSV file in your <MQL5>\Files directory. The script Sample.mq5 will read the CSV file and print the values of the CSV file.
