Why on FileStream File.Create i'm getting an exception and it's not creating the directory and the file ?

Question

This is the code :

FileStream fs=File.Create(settings);
fs.Close();

settings contain : 

"C:\\Users\\bout0_000\\AppData\\Local\\ScreenVideoRecorder\\ScreenVideoRecorder
\\settings\\settings.txt"

But instead of creating it i'm getting an exception on the FileStream line :

The type initializer for 'ScreenVideoRecorder.Options_DB' threw an exception

The full exception :

System.TypeInitializationException was unhandled
  HResult=-2146233036
  Message=The type initializer for 'ScreenVideoRecorder.Options_DB' threw an exception.

I understand that the exception say that the directory+file is not exist. The idea is that the FileStream will create it but it's not. And i want to use this FileStream so what's wrong ?

Answer 1

The message inside the stacktrace says it:

Could not find a part of the path 'C:\Users\bout0_000\AppData\Local\ScreenVideoRecorder\ScreenVideoRecorder\settings\settings.txt'.

You need to create the directory path first

I understand that so what is the line : 

FileStream fs=File.Create(settings);

Do ?

It's creating only the file without the directory ?

Hi,

Wrong assumption. The purpose of filestream is just to create/read files (it could be counter productive as if for some reason your path is wrong it could just end up with using this wrong location being used without noticing anything).

You can still "opt-in" for this by using explicitely http://msdn.microsoft.com/en-us/library/54a0at6s.aspx to create a Directory and all its subdirectories (but you'll have to exclude the file name from this path).
