Count the number of files in one directory

Questions & Answers

Hello,

I’m trying to make a kind of music player. I intend to create a folder, “music”, in which people will put their songs in.
But I don’t want unity to just open them. I want unity to count the number of songs in the folder and, depending on the number, to take different actions.

Is there any easy way to do this?

You can use the System.IO.DirectoryInfo class.

Adapted from the example they gave:

public static long DirCount(DirectoryInfo d)
{
    long i = 0;
    // Add file sizes.
    FileInfo[] fis = d.GetFiles();
    foreach (FileInfo fi in fis)
    {
        if (fi.Extension.Contains("mp3"))
            i++;
    }

    return i;
}
