Thanks works fine.

What is the exact reason ReadWrite access is needed though, even though you just want to read?

Man, thank you for sharing this snippet.

I am developing a VSTO addin that uploads the current open file. It required the built-in File.ReadAllBytes() which obviously threw an error as File.ReadAllBytes() attempts to close the file after reading it’s contents.

Now I am using YOUR method which works flawlessly.

PS: I shared your method as an alternative solution to the proposed ones here:

Nice try with reflector, but what if you try to close your stream at the end of your method, something like this:

fs.Close()

Hope this help
