c# : Loading typed data from file without casting -

-

is there way avoid casting non-string type when reading data text file containing exclusively integer values separated integer markers ('0000' example) ?
(real-life example : genetic dna sequences, each dna marker being digit sequence.)

edit : sample data : 581684531650000651651561156843000021484865321200001987984948978465156115684300002148486532120000198798400009489786515611568430000214848653212000019879849480006516515611684531650000651651561156843000021 etc...

unless use binary writer , read bytes, rather text (because how data written @ first),
i think funky idea, "no" straight answer this.
wanted definitive confirmation here, sure.

i welcome intermediate solution write/read kind of data efficiently without having code custom reader gui display outside app, intelligibly (in generic reader/viewer).

rather casting, should use .tryparse(...) method(s) of types trying read. more type-safe solution.

and answer question, other using binary file, there not (to knowledge) way without casting (or using tryparse methods)

Javascript line number mapping -

magically formatted comments change reported line number of javascript errors in browsers; this: //@line n "f" n line number , f file name. unfortunately, //@line appears ungoogleable. know there documentation on feature, , browsers support it?

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

-
something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

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.
