Noob problem with C# in unity

line 54 you forgot " symbol

string[] line_vaulues = line.Split(","); // - change to this

Thanks for that but now I am getting a error at line 61,20: error cs8025: Parasing error

Either you didn't copy your entire class into that code snippet or you are missing quite a bit of code in your class :)

C# is done in blocks of code surrounded with { and }. So you have:

     void LoadDialouge(string filename)
       {
           string file = "Assets/Resources/" + filename;
           string line;
           StreamReader r = new StreamReader(file);
   
           using(r)
           {
               do
               {
                   line = r.ReadLine();
                   if(line !=null)
                   {
                       string[] line_vaulues = line.Split(",");
                       DialougeLine line_entry = new DialougeLine(line_values[0], line_values[1], int.Parse (line_values[2]));
                       lines.Add(line_entry);
                   }
               }
   
               while (line != null);
               r.Close();

You see that LoadDialog opens with a {, then 'using' opens with a {, then 'do' opens with a {. You close the 'do' on line 58 but do not close the 'using', LoadDialog or the class itself. That is where the suggestion of adding }}} comes in. Adding those close the 'using', LoadDialog and class blocks of code.

Regarding further errors, it's best to post them so we know what you are experiencing. My quick review shows your line 54 has 'line_vaulues' (extra 'u') where line 55 is looking for 'line_values'.

Also, line 54: line.Split(",")... Split requires a character, not a string. Try changing those double quotes to single quotes: line.Split(',');
