asked on

c# can you write to a file if the path you give does not exist?

Is there a way to write to a file, creating the path if it does not exist?

say I want to write to c:\program files\mydir\mydir2\test.txt

1. is there a way to just specify that path and have the code create it if it doesn't exist?
2. if not, how can I create the path, but only if it does not exist?

Thanks guys, but I don't think I made myself clear. The path does not exist and I want to create it without having to do it manually

this works
FileStream fs = new FileStream(@"c:\test.txt", FileMode.OpenOrCreate, FileAccess.ReadWrite);

this does not, and it is what I am trying to do
FileStream fs = new FileStream(@"c:\thisDirDoesNotExistYet\MeEither\test.txt", FileMode.OpenOrCreate, FileAccess.ReadWrite);
