File creation and naming increment

[PIEBALDconsult]

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.

I know. I don't think there's any way around a try/catch. I would still opt for a database.

Didn't the original poster mention the API?

I'm using C# with ASP.NET.

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)

Oh, no, I see, you did.

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.
