Question

I want to persist some data into a text file in my C# application. I added the text file to the root of my project.

How do I access it now? Will this file be embedded with my exe or what?

Answer 1

First, make sure that you right click the file and select “Copy to Output Directory”.

Second, the file will not be embedded inside of your Executable. It will be a normal *.txt file alongside your *.exe and you would access it as such:

StreamWriter sw = null;
FileInfo fi = new FileInfo(Path.Combine(Application.StartupPath, "filename.txt"));

if(fi.Exists)
    sw = new StreamWriter(fi.Open(FileMode.Open));
