File creation and naming increment
-
Incrementing the integer requires the following steps: 1) Find the highest file 2) Attempt to create the next number 3) Repeat on failure A time stamp requires: 1) Attempt to create the file 2) Repeat on failure Unfortunately, only the Win32 API allows you to do this without a try catch loop which I find poor practice.

Most of this sig is for Google, not ego.You can check to see if a file with that name already exists.

Doesn't work in concurrent systems as the check for existence and creation have to be the same act, otherwise File.Exists then File.Create can fail.

Using the Win32 API is a perfectly valid way to overcome limitations in .NET. (Or at least a way to cut off your nose to spite your face)

Thank you all for your posts. It's been helpful. I'm still a little stuck, but I have the general idea. The files may get deleted, so I will need to take that into account. Also, I'm not using any database and for this application wont be using one. This is what I have so far. Please let me know if there are better methods:
public void filecount(string file)
{
int x;
int y;
string file;int filepaths = Directory.GetFiles(@"C:\Desktop\Request", "*txt").Length;
x = filepaths +1;StreamWriter sw;
sw = File.CreateText(@"C:\Desktop\Request\Text" +y +".txt");
file = Path.GetFileName(@"C:\Desktop\Request\Text" +y +".txt").ToString;
sw.Close();return file;
}public void btn_Click(object sender, EventArgs e)
{
filecount(file);
}Thanks again for helping a newbie out!
This won't work - in fact I don't think it will compile. 1 The return type is void but the function tries to return a string. 2 The parameter name (file) conflicts with the local variable also called file. 3 The value of y is not set but is used to construct the file name. Couple of other comments. 1 Why use the x and y variables when you have filepaths. You could just set it to Directory.GetFiles(@"C:\Desktop\Request", "*txt").Length + 1. Then use it instead of x or y. 2 This approach does not deal with deleted files. Suppose there are three files originally (text1.txt, text2.txt, text3.txt). Then text1.txt is deleted. What will the file count be? 3 The function is named filecount but it actually tries to return the next filename. 4 Read some of the suggestions carefully - there's good stuff in them that should solve the problem.
