Use a CSV suffix file as the configuration file

InProgramWhen the CSV suffix file is used as the configuration file during design, it is particularly convenient to edit the configuration file.CodeTo demonstrate how to write and read data.

1. Write files

When writing a file, use the fprintf function to write data, and use commas to separate the attributes of each configuration file.

File * _ dbfile = fopen ("D:/dotnet.csv", "W ");
If (_ dbfile)
{
// Write a file
Fprintf (_ dbfile, "A, B, C, D, E, F, GDD ");
Fclose (_ dbfile );
}

2. Read files

When reading a file, you can use the fgets function to read the data in each row in the _ Buf function.
Char _ Buf [500];
File * _ dbfile2 = fopen ("D:/dotnet.csv", "R ");
If (_ dbfile2)
{
// Read from the file
Fgets (_ Buf, 499, _ dbfile2 );
Fclose (_ dbfile2 );
}
