Opening Files[C Sharp]

[RealityFix]

What I basically want to do is open a file and make the program grab the files that are in the folder. Oh have some sort of way to use two files at once.

Im making a little program where a person makes a list of players and monsters and I hate using datafiles. I kinda suck at them >.>
So I just think it would be easier to use two seperate files then one file holding monsters and players.

Any tips? or Better ways to pull this off?

Check out the following static method.

C#:

System.IO.Directory.GetDirectories(string dir)

.

Personally I'd look into serialization in order to store your settings and states. It's pretty easy.

[RealityFix]

Any links to that serialization? I just want the easiest way possible at doing this >.>

Me = crappy at datafiles ;_;

Why not use a command line interface to input data? Under the command line interface you could ask how many players and monsters should be generated, name them and then build the lists from some simple input. You don't need no stinkin' no files, IOW.

this program has to use datafiles. Its what the whole assignment is about. The user has to be able to save and open the files and such.

Thanks rdrake.

The site uses some functions we haven't been taught yet in C#.

Is there a slight possibility of a easier technique?

Ah, that wasn't stated in the initial post. Some people do these kinds of things for fun.

Well I'm not having fun with this >.> To damn irritating.

Hate to double post but I get this weird error and i have no idea what to do with it >.>

Error 1 Static member 'DungeonsAndDragons.SearchAndSort.Shell(string[], string[], int)' cannot be accessed with an instance reference; qualify it with a type name instead C:\Documents and Settings\Owner\Desktop\DungeonsAndDragons2\DungeonsAndDragons2\DungeonsAndDragons\DungeonsAndDragons\DungeonsAndDragons\Form1.cs 84 21 DungeonsAndDragons

I have no idea what this is T_T

You're accessing a static method on an instance variable instead of the type. Post the code that's giving you the error if you're still stuck.

[RealityFix]

The code is a little confusing. I didn't write the search and sort thing I grabbed it off my teacher (Im a lazy bugger when it comes down to it)

but what I think your saying is that because my search thing is a static and my OpenFile method is just a public void that it will not work right?

C#:

//(public void OpenFile)   try             {                 openFileDialog1.Reset();                 openFileDialog1.InitialDirectory = Application.ExecutablePath;                 openFileDialog1.Filter = "Text files (*.txt)|*.txt|" + "All files|*.*";                 openFileDialog1.FilterIndex = 1;                 if (openFileDialog1.ShowDialog() == DialogResult.OK)                 {                     //string s = Application.StartupPath;                     //string f = s + @"\albums.txt";                     FileName = openFileDialog1.FileName;                     r = new StreamReader(FileName);                     string WholeLine;                     while ((WholeLine = r.ReadLine()) != null)                     {                         c++;                         lines = WholeLine.Split(',');                         NameMon[c] = lines[0];                         borrower[c] = lines[1];                     }                     //r.Close();    In finally statement below                     //n = c;                     //add filename to statusbar                     toolStripStatusLabel1.Text = "File Loaded";                    // Search.Shell(NameMon, borrower, n);                 }

C#:

public static void Shell(string[] albn, string[] borrown, int u)         {             int gap = u;             int maximum, iplusg, ex;             string temp = "";             do             {                 gap = gap / 2;                 maximum = u - gap;                 do                 {                     ex = 0;                     for (int i = 1; i <= maximum; i++)                     {                         iplusg = i + gap;                         if (albn[i].CompareTo(albn[iplusg]) > 0)                         {                             temp = albn[i];                             albn[i] = albn[iplusg];                             albn[iplusg] = temp;                             temp = borrown[i];                             borrown[i] = borrown[iplusg];                             borrown[iplusg] = temp;                             ex = ex + 1;                         }                     }                 }                 while (ex != 0);             }             while (gap >= 1);         }

C#:

Search.Shell(NameMon, borrower, n);

Is "Search" an object or the name of the class where Shell() is?

If it's an object then you're doing it wrong. Call this instead.

C#:

SearchAndSort.Shell()

[RealityFix]

C#:

SearchAndSort Search = new SearchAndSort();

Sorry forgot to include the part above the try{}.

[rdrake]

Yup, doing it wrong. The method is static, you absolutely have to call it as such.

C#:

SearchAndSort.Shell(NameMon, borrower, n);

Notice how I'm calling the method on the class name, not an instance of that class. Try the above code and it should work just fine.

Also please in the future try to be a bit more careful when including bits of code in your post. Some of your questions are hard to understand due to missing code fragments. You're better off including too much than not enough.

Thanks!

And I will put more data in my questions in the future.
