How to read file from the installation folder of app using c#?

Question

Hi

I am reading a file using File.ReadAllText("filename.txt"). This file is located in very same folder where the .exe file is located (c:/program files/installation folder). But windows app looks into System32 folder for this file by default.

**I don't want to hard code the path of the file.

Answer 1

string path = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase );

Gives the directory of the exe. So using that with Path.Combine will give the desired result:

string filenamelocation = System.IO.Path.Combine(path, "filename.txt");

Answer 2

So you need directory of your application? In that case, there are some good answers already on SO, for example:

Answer 3

Try this function:

using System.Reflection;

private string MyDirectory()
    {
        return Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
    }

Then use

File.ReadAllText(MyDirectory() + @"\filename.txt");

Answer 4

A lot shorter

File.ReadAllText(AppDomain.CurrentDomain.BaseDirectory + "filename.txt");
