Azure中未处理的异常

Question

I am in way over my head here, trying to program a code to work on a website in Azure. This is just supposed to be a demonstration for a presentation I have in the cloud. I wont be getting marks on this program, but it helps me to display the capabilities offered by Azure.

This may be vague, but if you can take a look at this error message and let me know if there's anything obvious let me know.

I'm assuming you're using Azure Web Apps (websites). That being the case: Looks like you're making calls to RoleEnvironment , which is specifically for web/worker roles, and not Web Apps.

I posted a similar answer several years ago, with a bit more detail, here .
