How to Reliably Determine the Current Execution Directory in C#?

Finding Your Application's Execution Directory in C#

Many applications need to know their current execution directory to correctly handle files and other resources. While methods like System.Windows.Forms.Application.StartupPath might seem straightforward, they aren't always reliable.

Here's the most robust way to get the path:

Recommended Method:

Use Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);. This directly targets the executing assembly's location, providing consistent results regardless of how the application was launched.

Alternative:

As noted by Soner Gönül, System.IO.Path.GetDirectoryName(Application.ExecutablePath); is another viable option. This retrieves the path of the entry assembly, which usually matches the execution directory.
