.net - Why does System.IO.Directory.GetFiles does not have a List(Of String) return overload? -


i have found overloads return array of strings. there specific reason why there no list(of string)?

i have write

dim nnewstringarray() string redim nnewstringarray(0) nnewstringarray = system.io.directory.getfiles(uinitdir)

instead of being able write

dim nnewlistofstring new list(of string) = system.io.directory.getfiles(uinitdir)

i feel redim bit old school.

i can think of 3 reasons (in no particular order):

  1. when method developed there no generics, , no list<t>. string[] best strongly-typed option available @ time.

  2. you can't overload methods return type, have either called getlistoffiles() (bad) or breaking change (very bad)

  3. it's easy do:

    dim nnewlistofstring new list(of string) (system.io.directory.getfiles(uinitdir))

plus don't need redim array mentioned in comments question. can do:

dim nnewstringarray() string nnewstringarray = system.io.directory.getfiles(uinitdir)

or just

dim nnewstringarray() string = system.io.directory.getfiles(uinitdir)

if prefer. reason turn results list if going add items it. pretty else can done array.

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac

apache - How do I stop my index.php being run twice for every user -

we've got webapp initial html served using apache , php. i noticed index.php being run twice every request. seems caused / effected rewrite rules in our .htaccess - rewritecond %{http_host} ^(www\.|hotels\.)ourdomain\.com$ [nc,or] rewritecond %{server_name} ^(www\.|hotels\.)ourdomain\.com$ [nc] rewriterule (.*) http://ourdomain.com/$1 [r=301] rewriterule ^hotels/([^/]+)/?\??(.*)$ ?d=$1&$2 [qsa] the final rule moving parameter url path query string. i.e. http://ourdomain.com/hotels/vegas?someparam=1 becomes http://ourdomain.com?d=vegas&someparam=1 if go directly query string version index.php run once. if use url redirected, index.php run twice (i'm checking adding error_log('end of index.php') file). so example going http://ourdomain.com/hotels/paris hits file twice http://ourdomain.com?d=paris hits once. i've seen this question , had @ blog mentioned , , can't find empty string url's (i've tried using yslow process). ...
