Question by Noaal · May 30, 2014 at 07:56 AM · highscoressystem.iotxt

Highscores in text file

Hi, I want to store highscores in external txt file and when game is over read them from this file. My file is something like that: "PlayerName,score". Here is my code:`int PlayerScore; FileStream fso = new FileStream (@"Highscores.txt", FileMode.Append, FileAccess.Write, FileShare.Read); FileStream fsr = new FileStream (@"Highscores.txt", FileMode.Open, FileAccess.Read, FileShare.ReadWrite);

 public void WriteHighScore(string name, int score)
 {
     
     using (StreamWriter sw = new StreamWriter(fso))
     {
         sw.WriteLine(name +","+ score);
         sw.Close();
     }
 }

 public string ReadHighScore(string name,int newHscore)
 {
     using (StreamReader sr = new StreamReader(fsr)) 
     {
         string line;

         while ((line = sr.ReadLine()) != null)
         {
             string [] words = line.Split(',');
             foreach (string word in words)
             {
                 int Hscore = Int32.Parse(words[1]);
                 if(newHscore > Hscore)
                 {
                     WriteHighScore("Drik",newHscore);

                 }
             }
             return line;

         }

     }
     return null;
 }

When I'm at the gameover screen I have 2 errors:

ArgumentException: Can not write to stream

System.IO.StreamWriter..ctor (System.IO.Stream stream, System.Text.Encoding encoding, Int32 bufferSize) (at /Users/builduser/buildslave/monoAndRuntimeClassLibs/build/mcs/class/corlib/System.IO/StreamWriter.cs:95) System.IO.StreamWriter..ctor (System.IO.Stream stream) (wrapper remoting-invoke-with-check) System.IO.StreamWriter:.ctor (System.IO.Stream) HighScoreManager.WriteHighScore (System.String name, Int32 score) (at Assets/Scripts/HighScoreManager.cs:23) HighScoreManager.ReadHighScore (System.String name, Int32 newHscore) (at Assets/Scripts/HighScoreManager.cs:44) GameOver.OnGUI () (at Assets/Scripts/GameOver.cs:33)

What is problem here?
