Let's say I have a class:
It's almost certainly your code. You are using that file name somewhere else in the program.
You can also use File.Exists() to help you avoid the exception.
Your debugger should be breaking when you hit the exception. If you look at the contents of the variable being passed you will probably see the wrong file name in there.

You need to make sure you are closing your file. Just like memory leaks there are resource leaks. My guess is you are leaking your file because you are not closing it, this will make it not avaliable by the later run.

Try reading/writing to your file in with a "using" construct like this:
It's doing exactly what the other members have suggested (close the file), but will do it automatically at the end of the "using" block.
using (FileStream stream = new FileStream(fileName, FileMode.Read)){ //Do something with the file}//File is automatically closed for youIt's doing exactly what the other members have suggested (close the file), but will do it automatically at the end of the "using" block.

Well to start off, I was closing my file, sorry for not saying that. But as it is, that's not the problem. I took DaWanderer's suggesstion, but still to no avail. Here's the code I am using after making the changes:
-AJ
//The function that takes the string parameterpublic void LoadHeightData(string fileName) { using (StreamReader sr = new StreamReader(fileName)) { short x = Int16.Parse(sr.ReadLine()); short y = Int16.Parse(sr.ReadLine()); heightData = new int[x, y]; for (int i = 0; i < y; i++) { for (int b = 0; b < x; b++) { int high = Int32.Parse(sr.ReadLine()); heightData[x - 1 - b, y - 1 - i] = high; } } //FileInfo f = new FileInfo(fileName); //f.Delete(); width = x; height = y; } }//The function using the function from aboveprivate void Visualize_Load(object sender, EventArgs e) { terrain.InitializeDevice(this, cam, out device); //No matter what file name I use here, it always complains that //the first file name used doesn't exist. Unless, of course, //that file does exist. terrain.LoadHeightData(@"C:\anotherperlin.lot"); terrain.InitInput(this); terrain.CameraPositioning(device, this); terrain.VertexDeclaration(device); terrain.IndicesDeclaration(device); }-AJ
You're sure you're not calling that function from elsewhere? Try putting a breakpoint (or a Console.WriteLine) on line 1 of LoadHeightData to find out what it's being passed, or whether it's being called twice.
There's nothing wrong with the code posted as far as I can see.

*nervous laugh* Hey guys. I figured out the problem. *another nervous laugh* I was editing the wrong source file. The code was just fine, although I do appreciate the suggesstion to use the using (FileStream...) statement to ensure the scope and everything. Thanks to all who helped me out. [smile]

Hehe. Oh, that's so easy to do. (That, or editing the right file but from the wrong project so it doesn't get compiled.)
Glad you sorted it out :).
