How to get project file path in C#

How to get project file path in C#?

Below are a few common approaches to get the project file path or the project directory:

// get the current WORKING directory (i.e. \bin\Debug)
string workingDirectory = Environment.CurrentDirectory;

// or

string workingDirectory = Directory.GetCurrentDirectory(); //gives the same result

// get the current PROJECT bin directory (ie ../bin/)
string projectDirectory = Directory.GetParent(workingDirectory).Parent.FullName;

// get the current PROJECT directory
string projectDirectory = Directory.GetParent(workingDirectory).Parent.Parent.FullName;

You can also try one of this two methods.

string startupPath = System.IO.Directory.GetCurrentDirectory();

string startupPath = Environment.CurrentDirectory;

When a project is running on IIS Express, the Environment.CurrentDirectory may point to the IIS Express installation directory (e.g., C:\Program Files (x86)\IIS Express), not the location where your project files are stored.

This is because IIS Express is hosting your application, and its working directory may differ from your project's directory. Therefore, using Environment.CurrentDirectory in such a scenario might not give you the correct project path.

This is likely the most appropriate directory path for different types of projects.

string path = AppDomain.CurrentDomain.BaseDirectory;
