c# - LightInject IoC container resolve type by a custom method? -


is possible in lightinject ioc resolve type based on custom method?

eg resolver call method this

public interface imytype {} public class myeventype : imytype {} public class myoddtype : imytype {} public static int foo;      public static imytype resolvetype() {    if (foo % 2 == 0)        return myeventype;    return myoddtype; }

how write container.register method calls above method in order resolve dependency?

lightinject allows register specific methods factory resolver methods allow construct type when resolve interface. 

public class mytyperesolver {     public static int foo;         public static imytype resolvetype()     {         if (foo % 2 == 0)             return new myeventype();         return new myoddtype();     } }

when registering interface, instead of registering concrete type, register factory method returns concrete type.

void main() {     var container = new lightinject.servicecontainer();     container.register<imytype>(factory => mytyperesolver.resolvetype());      var instance1 = container.getinstance<imytype>();     instance1.dump();      mytyperesolver.foo = 1;      var instance2 = container.getinstance<imytype>();     instance2.dump(); }

instance1 has concrete type of myeventype , instance2 has concrete type of myoddtype.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
