Method FromFile

FromFile(string, string?, string?)

Creates a source that reads a file. Each read opens the file and checks that its length and last write time are still the ones it had when the source was created, so that a file that changes fails the read with an IOException instead of being uploaded with other content. Other processes can read, write and delete the file while a read has it open.
