c++ cli - ...array<Object^>^ args -

-

i'm reading c++/cli. see stuff:

object^ createinstancefromtypename(string^ type, ...array<object^>^ args) { if (!type) throw gcnew argumentnullexception("type"); type^ t = type::gettype(type); if (!t) throw gcnew argumentexception("invalid type name"); object^ obj = activator::createinstance(t, args); return obj; }

when calling it:

object^ o = createinstancefromtypename( "system.uri, system, version=2.0.0.0, " "culture=neutral, publickeytoken=b77a5c561934e089", "http://www.heege.net" );

what ...array^ args? if remove ... ,there's complied-error:

error c2665: 'createinstancefromtypename' : none of 2 overloads convert argument types 1>        .\myfourthcplus.cpp(12): 'system::object ^createinstancefromtypename(system::string ^,cli::array<type> ^)' 1>        1>        [ 1>            type=system::object ^ 1>        ] 1>        while trying match argument list '(const char [86], const char [21])'

like c++, c++/cli has mechanism variable amount of arguments. ... in front of ...array<object^>^ parameter means.

for type safety c++/cli designers added managed syntax declare type of variable array.

since it's passing parameter activator::createinstance() function, @ variable parameters activator function looking for.
