C# MVVM proper use of paths for deployment

Question

private void loadWordsFromFile()
{
    words = File.ReadAllLines("C:/Users/tony/Documents/Visual Studio 2013/Projects/Hangman/Hangman/Files/test.txt");
}

private void selectWord()
{
    WordsRemaining = words.Length.ToString();
    HangImage = new BitmapImage(new Uri("C:/Users/tony/Documents/Visual Studio 2013/Projects/Hangman/Hangman/Files/" + wrongGuesses + ".png"));
}

These are my paths. Could you please show me how to make the paths properly?

I'd like not to have the full path but a relative because in this way I cannot publish my app — coolside, Apr 21 '16 at 13:20
Create a `Files` folder in your Visual Studio Project and put all necessary files in that folder. In the Properties of each file set `Build Action` to `Content` and `Copy to Output Directory` to `Copy always` or `Copy if newer`. Thus the files will be copied to the output directory and can be accessed by relative paths like `Files/test.txt`. — Clemens, Apr 21 '16 at 13:23
it works for the loadWordsFromFile function but when I apply the following code for the image: HangImage = new BitmapImage(new Uri("Files/" + wrongGuesses + ".png")); it gives me the following error after startup: An exception of type 'System.UriFormatException' occurred in System.dll but was not handled in user code Additional information: Invalid URI: The format of the URI could not be determined. — coolside, Apr 21 '16 at 13:36

You can use this to get the current execution path

    Uri executingPathUri = new Uri(Assembly.GetExecutingAssembly().GetName().CodeBase);

    string executionFolderPath = Path.GetDirectoryName(executingPathUri.LocalPath);

Then, you can have a folder in your deployment directory that contains the files that you need.

Please never try to concatenate path using '+' operator. Always use

Path.Combine(.....)

public static string Combine(string path1, string path2, string path3, string path4);
