问题 I'm trying to do a simple file upload in asp.net core 2 razor pages. I have the code below. Please realize that it is imcomplete. When i run in my VS2017, I check my FileUpload object, and it is unfortunately null. I would hope that it is something besides null and I could create a stream to get some data out of it.
