Can a loaded DLL know where it is located?

I am building a DLL that is used by Office. When Office runs with it, I would like to identify where it is located. Is that possible?

ex. of code within the DLL when it is run within Office:

// should return C:\tmp\officeaddin.dll, 
// currently C:\Program Files\Microsoft Office\Office 12
MessageBox.Show(Application.StartupPath)
Solution

  • The following should work even if running inside of Office:

    Getting the path of the current assembly

    (It basically boils down to Assembly.GetExecutingAssembly().Location, but see the link above for more detailed information.)
