Is it possible to change the CanWrite property in a FileStreamResult's FileStream?

Question

I want to try this in order to discard a possibility of why my code is not working as expected. Thanks in advance!

Answer 1

Just pass steam that has CanWrite set the way you want in constructor. MemoryStream is an option as it allows both R/O and R/W modes.

I.e. if you just need some result use following (indeed you can pass real data as buffer too):

return new FileStreamResult(new MemoryStream(new byte[4], writable:false));
