c# - Using 'switch' with strings in resource file -

-

i have bunch of strings in resource(.resx) file. trying directly use them part of switch statement (see sample code below).

class test {     static void main(string[] args)     {         string case = args[1];         switch(case)         {             case stringresources.cfg_param1: // something1                  break;             case stringresources.cfg_param2: // something2                 break;             case stringresources.cfg_param3: // something3                 break;                           default:                 break;         }     } }

i looked @ of solutions, of them seem suggest need declare them const string dislike. liked top voted solution question: using collection of strings in switch statement. need make sure enum , strings in resource file tied together. know neat way of doing that.

edit: found this great answer while researching how use action:

you use dictionary<string, action>. put action (a delegate method) each string in dictionary , search it. 

var actions = new dictionary<string, action> {     { "string1", () => method1() },     { "string2", () => method2() },     { "string3", () => method3() }, };  action action;  if (actions.trygetvalue(mystring, out action)) {     action(); } else {     // no action found }

as sidenote, if method1 action or void method1() method (with no parameters , no return value), 

    { "string1", (action)method1 },

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.
