关于[Increase ASP.NET File Upload Limits]的摘要:
By default, ASP.NET and IIS protect us from large requests by putting hard limits on the transmitted size. IIS buffers files in our server’s memory before passing the byte array to ASP.NET. IIS’ default limit is 4MB and ASP.NET Core has a default of 30MB. To put that in perspective, one 12 megapixels digital picture can average 3.6 megabytes.
