How to get the path of the uploaded file within the AppBundle?-CodePudding

We are using Autodesk Forge's Design Automation API. We have an AppBundle ready and we put an .rfa file into the same folder which contains the .dll file. When the AppBundle is unzipped on the Forge servers, which path can lead to our .rfa file? (how can we access it?) Our goal is to place the attached Family file's contents into the input file which is being uploaded with the API, and the result should be a new file which contains the additions from the file which we uploaded within the AppBundle. The process works when testing with Revit locally, but it doesn't work with the API. In the report we are retrieving it's obviously pointing out that the attached file cannot be found:

Autodesk.Revit.Exceptions.FileNotFoundException: T:\Aces\Jobs\ced628d35ecf4412b68c024e2cec098b\something.rfa

On the code side, we are trying to access the .rfa file via this path:

static string currentDir = Environment.CurrentDirectory;
static string path_input =  currentDir @"\something.rfa";

This seemed as a logical path, but as it turned out, it's not.. Is there a way to access the .rfa file inside the uploaded AppBundle? I took a look at the Restrictions but reading the file from the AppBundle is not mentioned as restricted or not approachable. Am I missing something?

We have a blog post on how you can either pass in the app bundle path in the commandLine parameter or find the path via the location of the add-in dll: https://forge.autodesk.com/blog/store-template-documents-appbundle

CodePudding user response：

A .NET assembly knows its own path. You can call System.Reflection.Assembly.GetExecutingAssembly().Location within it to find the current path of the dll. You can then compute the path of the .rfa file relative to the folder of the dll and use it / open it. Thus you should be able to open any file you package along with your addin in your appbundle.

You can simply modify your code to:

static string assemblyLocation = Assembly.GetExecutingAssembly().Location;
static string assemblyDirectory = Path.GetDirectoryName(assemblyLocation);
static string path_input = assemblyDirectory @"\something.rfa";

One thing to note however, is that you only have readonly access to files in appbundle. If your code relies on modifying these during execution, then you may simply copy the source rfa file to the current working folder and then work with the copied file instead.
