Saving a file in a specified folder inside my project

Question

I am creating an Xml file and I want to save it in a specified folder inside my project within the solution where I can access it in the Solution Explorer.

How can I specify the path so that a folder is created and the xml file saved inside it?

As it is at the moment it creates the file in the root directory of my project and I cannot view it in Solution Explorer.

 XmlSerializer serializer = new XmlSerializer(typeof(BoxSet));
 TextWriter textWriter = new StreamWriter("../../Box.xml");

Sorry, still a newbie...am I missing something.?

Answer 1

You can specify the path when you declare a new StreamWriter.

TextWriter textWriter = new StreamWriter("../../Box.xml");

This comes down to:

• ../ - Go up one directory
• ../ - Go up one directory
• Box.xml file here

So when you want the file created in a folder inside the root folder you could use:

• "../foldername/Box.xml"

But if you don't want to rely on your current file location you can also use:

AppDomain.CurrentDomain.BaseDirectory

That would make:

var path = String.Format("{0}foldername\Box.xml", AppDomain.CurrentDomain.BaseDirectory);
TextWriter textWriter = new StreamWriter(path);

Hope this helps.

Answer 2

Instead of using AppDomain.CurrentDomain.BaseDirectory you can just do it this way:

    TextWriter textWriter = new StreamWriter("foldername\\Box.xml");

When you don't add anything, the basedirectory is automatically assumed.
