Using absolute path with streamwriter C#

I am trying to use streamwriter to create a text file in the my documents folder, however it thinks i am using a relative path when i am actually using a full path.

I am trying to create the file using this path: "%HOMEPATH%/My Documents/", but it treats this as a relative path.

Any help would be appreciated, thanks.

Check the environment variables from the command prompt. I see the following on my machine -

HOMEDRIVE=C:

HOMEPATH=\Users\foo

So try %HOMEDRIVE%%HOMEPATH% instead to fix your problem

I would resolve the environment variable using some API and then input the path that includes the absolute path ("C:.....") to the StreamWriter

You could use Environment.SpecialFolder Enumeration as suggested by David Staratton.

You should use Environment.GetFolderPath - which in this case would avoid you hard-coding My Documents at all:

string docs = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);

If you wanted to get a directory name relative to that, you should use Path.Combine:

string fooDocsDirectory = Path.Combine(docs, "foo");

The correct way to get a users' Documents folder in .Net is to use Environment.GetFolderPath() and pass in Environment.SpecialFolder.MyDocuments.

Use System.Environment.SpecialFolder.MyDocuments to get to the My Documents path, rather than attempting to use system variables.
