How to know path link of Revit Link Instance in case Link is unload?

[Shai.Nguyen]

Hi everyone,

I have a question. I tried to access the path of Revit Link Instance if the Link file is not loaded (in some reasons).

I used: RvtDocument doc = rvtlink.GetLinkDocument(); But when I debug, doc is null so I can't get doc.PathName.

I tried to reload in Revit, and Revit still remember the old path of Link.

How can Revit get this Path and where can I get that?

Thank you in advanced. Your solution is highly appreciated.

Demo : 

IDictionary<ExternalResourceType, ExternalResourceReference> resourceReferences = RevitLinkType.GetExternalResourceReferences();
resourceReferences.Values.First().InSessionPath;
