How to determine that caught LibGit2SharpException is the HTTP 401 error?

Question

When I try to fetch changes (RepositoryExtensions.Fetch) using invalid credentials LibGit2Sharp throws LibGit2SharpException with the following message:

An error was raised by libgit2. Category = Tag (Error).
Request failed with status code: 401

Since there might be other errors is there any way to determine that the exception is in fact HTTP 401 error without parsing the message?

Answer 1

Unfortunately, I don't think it is currently possible to get more specific information from that exception. This is something that would be a useful addition. Would you want to open an issue on the LibGit2Sharp project for this? If not, I will create one shortly.
