asp.net mvc 2 - MVC2 controller method that can accept unknown number of variables? -

-

i need work below posted data, or variant thereof. basically, need post variable number of key-value pairs represent question id , answer string.

how write asp.net mvc2 controller method signature accept unknown number of key-value pairs?

attachmentid=8809&question_712=&question_713=&question_714=&question_715=&question_716=&question_717=&question_719=&question_720=&question_721=&question_722=&question_723=&question_724=&question_725=&question_726=&question_727=&question_731=&question_738=&question_739=&question_741=&question_742=&question_743=&question_744=&question_745=&question_746=&question_747=&question_748=

please note in example, there 26 question keys empty values. there may more or less keys , may or may not have value. can reformulate way data sent client, if best solution rethink way sent, i'm open that.

this data formcollection collects. it's used in automatically generated controllers default. i.e. public actionresult edit(int id, formcollection collection)

c# - Is it possible to remove an existing registration from Autofac container builder? -

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
