Reading the file into memory John Brett Sep Reading the file into memory might be fine for small ish files, but unnecessary. For larger files, or the generic solution, I'd suggest you open a FileStream and pass that to the File method.
That way, the contents of the file flow directly from the filesystem through the network to the client, and don't have to be pulled in their entirety in memory before sending the file. The end result will perform quicker, waste fewer resources if the client aborts the download, and take considerably less memory. But in this kind of scenario where a pre-existed files are provided for download on button click, these files are of very small size normally.
Further haven't used that much FileStreams, So it would be nice if you could provide a code chunk for that. Re: Reading the file into memory User Sep
