.net - To check wether a specific project reference exists (C# Code, Preprocessor Directives ...) -

-

i'm new c# / .net hope there solution problem.

i'm working 2 different image-processing libraries have own classes represent images. because don't want use classes in own (private) class library, want implement own "myimage"-class supposed wrapper around both of other classes. (i have of course add functionality of libraries if missing).

my problem this: myimage-class needs reference both libraries compile, use myimage-class in projects 1 library available. find not difficult "add" or "remove" references image class project, don't want comment out code refers missing library.

so question is: somehow possible determine wether reference set preprocessing directive or attributes or code directly? or there better solution problem (a clever class design maybe?)

thanks help

i don't think there's preprocessor directive tell if reference has been added.

you split class 2 separate classes, 1 each library, suspect intention join 2 1 unified class.

what use 2 conditional compilation symbols (see properties | build), 1 methods specific first library, other second library. whenever class's code refers data members or functions specific the library, surrounded #if directive, referring appropriate symbol.

if intention not join classes, reed's , daniel's solutions more appropriate.

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.
