mvvm light - SimpleIoc (mvvmlight) - how to automatically register all classes implementing a particular interface -

using simpleioc want automatically register classes implement particular interface. couldn't see method on simpleioc's container automatically set code iterate through types registered. unfortunately code's not happy (see commented line).

var types = appdomain.currentdomain.getassemblies() .selectmany(s => s.gettypes()) .where(typeof(ifoo).isassignablefrom); foreach (var type in types.where(x=>x.isclass)) { container.register<ifoo, type>(); //this line won't compile type can't resolved compiler }

i realise there less elegant ways of registering classes (such hard coding "container.register" register each class interface) i'd able add together new implementations without having maintain updating ioc installer code. useful, @ point, me able register classes in other assemblies using same method.

any thought have alter create build (or there simpler/more elegant way this)?

update fex posted comment:

"you can iterate on types (like in question) , create reflection (in mill class) - (ifoo)activator.createinstance(type); - in fact that's how service locators / ioc containers internally (in simplify)."

i've updated code next works, 1 caveat (the implementations must have parameterless constructor, , dependencies must hence satisfied mill i'm using serve instances implementing ifoo). i've included mill registration info.

updated code:

// types implement ifoo... var types = appdomain.currentdomain.getassemblies() .selectmany(s => s.gettypes()) .where(typeof(ifoo).isassignablefrom); // register these types , utilize reflection instantiate each instance... foreach (var type in types.where(x=>x.isclass)) { var t = type; container.register(() => (ifoo)activator.createinstance(t), t.tostring()); } // inject registered instances of ifoo ifoofactory when it's instantiated. // note instances of ifoo must have own dependencies satisfied via // mill @ runtime before beingness served factory. container.register<ifoofactory>( () => new foofactory(container.getallinstances<ifoo>()));

c - Compilation of a code: unkown type name string -

c - Compilation of a code: unkown type name string - i have next lines of code compiler says following: "unknown type name 'string'" both in declaration , definition of function. can tell me what's wrong? thanks. #include <stdio.h> #include <stdlib.h> #include <string.h> void frecognizeclient(string *actualclient) there no string type in c. need utilize array so: char array[10]; then can pass in function: void frecognizeclient(char *actualclient); c arrays string compilation

java - Bypassing "final local variable defined in an enclosing type" -

java - Bypassing "final local variable defined in an enclosing type" - i'm writing programme , i'm getting "the final local variable asd cannot assigned, since it's defined in enclosing type". i provide illustration not code produces error aswell. have arraylist utilize later (if define within button can't utilize later on), outside of button, pressing button should give values arraylist. in illustration "create new arraylist" cause same problem. button btn = new button("asd"); final arraylist asd = new arraylist(); btn.setonaction(new eventhandler<actionevent>() { public void handle(final actionevent event) { asd = new arraylist(); //here's error.. } }); clear arraylist , add together values. java javafx
