problem in storeing highscore in xna gaming...:(

Question

public void gethighscxore() { Boolean boolwork = true; fileread = new FileStream(filename FileMode.OpenOrCreate FileAccess.Read); scoreread = new StreamReader(fileread); for (int i = 0; i Convert.ToInt32(texthscore1[i])

Try running this a few times and let me know whether you ever get a strange result when converting the string to an int: textthscore1[i] = 123455; // set value here. overwriting previous value if (plane_.score > Convert.ToInt32(texthscore1[i]) && i == j) { texthscore2[i] = plane_.score.ToString(); i++; if (i { texthscore2[i] = texthscore1[j]; }

I CANT FIND ANY MISSING STATEMNT .....IM HOPE LESS..:(

Vulpes · Answer

The probability of Convert.ToInt32 containing a bug is zero so you must be missing something somewhere. Is that number being entered in a text box and if it is are you performing any manipulations on it before Convert.ToInt32 is being called?

if (plane_.score > Convert.ToInt32(texthscore1[i]) && i == j) { texthscore2[i] = plane_.score.ToString(); i++; if (i { texthscore2[i] = texthscore1[j]; } sir here the portion of game in which texthscore is string in plane.score is intiger.... I can only think that sometimes 'string' can be parsed to an integer (e.g. 123 4567) and sometimes it can't (e.g. 12ab 1234). as per this pera ...i cannot understnd that im only convert initiger value of score 123455 like..then how can it generate 12ass5...... n sir isn't posible to always convert corectly string to int.... confusedblablblablaaba

I can only think that sometimes 'string' can be parsed to an integer (e.g. 123 4567) and sometimes it can't (e.g. 12ab 1234). If you can't be sure what 'string' will contain you could use this code instead: string s = 12ab; // or whatever int i; bool isValid = int.TryParse(s out i); if (isValid) { // do something with 'i' } else { // issue error message perhaps or alternatively proceed with i = 0 } Notice that if the string can be parsed to an integer int.TryParse returns true and the result is placed in the out paramater 'i'. If it can't be parsed to an integer int.TryParse returns false and a result of 0 is placed in the out parameter.

sir i done this last night...finaly i remove this error..im so happy:D i use IsolatedStorageFile instead of filestream...hurrry bt now one anoter problem is occuring.. that is....'System.FormatException' in this typ of line in my code int=convert.toint32(string); ...bt this error occure not always... what should i do knw

Vulpes · Answer

It's a difficult error to diagnose :( Can you post the exact error message and are you able to pinpoint on which line it's occurring?

YES SIR ITS WINDOWS PHONE APP......N STILL IM HOPELESS.....:( I THINK THERE IS ANY PROBLEM IN THE PROPERTIES OF TXT FILE AND PROJECT..COZ OF THIS ACCESS PROBLEM IS OCCURE.....

Vulpes · Answer

The code looks fine to me but if it's a Windows Phone app and the error is occurring when you try to use StreamReader I'd check this thread which offers a workaround even if the reason for the error remains obscure: http://stackoverflow.com/questions/20534714/methodaccessexception-for-streamreader-in-xna-windows-phone-app

here the code...there is none syntex error...... FileStream fileread; FileStream filewrite; StreamReader scoreread; StreamWriter scorewitte; public void gethighscxore() { Boolean boolwork = true; // create fo fileread = new FileStream(ok.txt FileMode.Open FileAccess.Read); scoreread = new StreamReader(fileread); for (int i = 0; i { texthscore1[i] = scoreread.ReadLine(); if (texthscore1[i] == null) { texthscore1[i] = 0; } } scoreread.Close(); fileread.Close(); if (boolwork) { int j = 0; for (int i = 0; i { if (plane_.score > Convert.ToInt32(texthscore1[i]) && i == j) { texthscore2[i] = plane_.score.ToString(); i++; if (i { texthscore2[i] = texthscore1[j]; } } else { texthscore2[i] = texthscore1[j]; } j++; } } filewrite = new FileStream(ok.txt FileMode.Create FileAccess.Write); scorewitte = new StreamWriter(filewrite); for (int i = 0; i { scorewitte.WriteLine(texthscore2[i]); } scorewitte.Close(); filewrite.Close(); } sir this is the proper code..this couch exception error System.MethodAccessException i think ther is any problem in fileaccesing... pls help me how can i resolve it

If that's an exact copy of your actual code then the only problem I can find is that your for statements will never end as they have just 'i' rather than i++ in the iterator part.
