FileStream and creating folders

Question

Just a quick question. I'm using something like this

FileStream fs = new FileStream(fileName, FileMode.Create); 

I was wondering whether there was a parameter I could pass to it to force it to create the folder if it doesn't exist. At the moment an exception is throw if folder isn't found.

If there is a better method then using FileStream I'm open to ideas.

Answer 1

Use Directory.CreateDirectory:

Directory.CreateDirectory Method (String)

Creates all directories and subdirectories as specified by path.

Example:

string fileName = @"C:\Users\SomeUser\My Documents\Foo\Bar\Baz\text1.txt";  Directory.CreateDirectory(Path.GetDirectoryName(fileName));  using (FileStream fs = new FileStream(fileName, FileMode.Create)) {     // ... } 

(Path.GetDirectoryName returns the directory part of the file name.)
