c# - Stream - Cannot access a closed Stream -


small issue i'm having stream, i'm getting exception in title.

i have inside using statement, inside loop, , posts i've seen remove using statement , "renew" it: cannot access closed stream of memorystream, how reopen?

the exception happens on second iteration of loop. have tried removing using statement no effect.

here's general idea:

for (blah blah blah)  {     using (stream strm = externalstreamprovider.getstream(some params)     {          if (stream.position != 0) //exception here on 2nd iteration             ...........     } }

however, using stream, abstract, cannot recreate mystream = new stream().

i using external stream provider, cannot change how stream fetched.

any ideas on how fix issue?

i apologize vagueness, please let me know if unclear.

it seems externalstreamprovider returning same stream instance every time... , since closed in first iteration, fails in second.

if expect working same stream in every iteration, should stream outside loop:

using (stream strm = externalstreamprovider.getstream(some params) {     (blah blah blah)      {          if (stream.position != 0)             ...........     } }

edit: saw comment:

when exception raised on stream.position brand new instance of stream on 2nd iteration

in case, explanation externalstreamprovider returning stream closed; problem not in code posted...

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
