I'm currently trying to load a simple text file and filter it by a certain string. In the text file I'm using a new line for each value and sometimes use a "--" to make things easier to read for me when viewing the .txt-file.

Now, when I load the file and split it by new lines I end up with a list of substrings, each representing a value I need. Plus, all the "seperators" I put into the file.

My goal is to clean the list from all the seperators and basically just remove them from the list. However, RemoveAll does not work and I found out that the strings containing "--" are not really "--", but something else, because using string.Equals("--") fails on them.

Somewhere when reading the data or splitting it, something happened to those parts, but I can't figure out what's happening.

Here's the code:

void Awake() {

_fileLines = new List<string>(); TextAsset txt = Resources.Load<TextAsset>("SubjectPages/test"); _fileLines = new List<string>(); _fileLines = txt.text.Split(new string[] { "\n" }, System.StringSplitOptions.None).ToList<string>(); _fileLines.RemoveAll(x => ((string)x) == ""); _fileLines.RemoveAll(x => ((string)x) == "--"); for (int i = 0; i < _fileLines.Count; i++) { Debug.Log(_fileLines[i] + " | " + (_fileLines[i].Equals("--")) + " | " + (_fileLines[i] == "--")); } }

Removing empty lines with RemoveAll seems to work fine.

    \$\begingroup\$ What happens if you open the file in some text editor and let it show all non-printable characters? \$\endgroup\$

    \$\begingroup\$ Have you tried printing out the character code contents of one of the array entries you want to remove, just to find out what's in it? \$\endgroup\$

  • \$\begingroup\$ @wondra I opened the file in notepad++ and it shows "CR" and "LF" after each line except for the last one \$\endgroup\$

    \$\begingroup\$ Debug.Log((int)myString[characterIndex]), no? My bet is that you're removing the LFs but not the CRs, so "--" doesn't match "--CR" \$\endgroup\$

I checked each character value for the lines containing "--" and they did indeed have a third character with a char value of 13. Looking it up this translates to "\r". So, instead of removing "--" from the list I am now removing "--\r" from the list and this works now :)

    \$\begingroup\$ Instead, you may want to split your lines on the pair \r\n rather than just \n. That will remove unwanted \r characters from all of your lines. \$\endgroup\$
