Retrieve current folder path

[jjesusdelpino]

Hi forum. Im trying to access to the Addins folder in which my dlls are installed:

C:\ProgramData\Autodesk\Revit\Addins\2019

I have tried: 

System.IO.Path.GetDirectoryName(Application.ExecutablePath);

wich output:

C:\Program Files\Autodesk\Revit 2019

And also tried:

Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData)

wich output:

C:\ProgramData

I can certainly add "\Autodesk\Revit\Addins\2019\" to the last one, but I wouldnt want to add this manually cause maybe someone change the instalation folder (is this even possible?) or the addins folder. Is there a way to retrieve "C:\ProgramData\Autodesk\Revit\Addins\2019" or wherever my dlls is placed with a single command order to minimize errors?

Regards.

On the application object there are properties you can make use of:

Application.AllUsersAddinsLocation

Typically: C:\ProgramData\Autodesk\Revit\Addins\<Year>

Application.CurrentUserAddinsLocation

Typically: C:\Users\<User>\AppData\Roaming\Autodesk\Revit\Addins\<Year>

It is a bad idea to hardcode parts of a path as in different environments the locations may not be as expected. In virtualised environment for example.

Try using:

using System.Reflection;

string thisAssemblyPath =    Assembly.GetExecutingAssembly().Location;

Or for a macro, try:

string thisAssemblyPath = this.AddinFolder.ToString();

Stever66 solution worked perfectly for me. Also in macro.

After looking API.chm, pretty sure RPTHOMAS108 solution also works perfectly but still havent been able to check because I havent been able to get ApplicationServices.Application.

Thank you two. Regards

Edit: also works perfectly. check here to get applicationservices.application (https://forums.autodesk.com/t5/revit-api-forum/autodesk-revit-applicationservices-application-onstar...)

You can get application as follows:

From IExternalCommand.Execute:

commandData.Application.Application

From IExternalApplication.OnStartUp/OnShutDown

application.ControlledApplication

From IExternalDBApplication.OnStartUp/OnShutDown

application

@stever66has probably given a more precise answer since it will list the location of your executing dll file (this can be elsewhere from the .addin file). Note also difference between .GetExecutingAssembly and .GetCallingAssembly.

Thanks for the clarification.
