Reflection on const variables

[Stabiplan BV]

Hi,

I am trying to find const variables outside a class. Thur far I did not
succeed. Without const, the variable is found but with const not.

So, how can I get hold on global const variables using reflection?

Regards,

// reflection.cpp : main project file.

#include "stdafx.h"

using namespace System;
using namespace System::Reflection;

const int test = 10023;

int main(array<System::String ^> ^args)
{
Module^ mod = Assembly::GetExecutingAssembly()->GetModules()[0];
Console::WriteLine( mod->Name );
FieldInfo^ info = mod->GetField("test",
BindingFlags:ublic|
BindingFlags::NonPublic|
BindingFlags::Instance|
BindingFlags::Static|
BindingFlags::FlattenHierarchy);
if ( info ) {
Console::WriteLine( "Found: " + info->Name );
}
array<Type^>^t = mod->FindTypes( Module::FilterTypeName, "t*" );
for( int i = 0; i < t->Length; i++ ) {
Console::WriteLine( t->Name );
}
Console::ReadLine();
return 0;
}

Global const variables by default have static scope, and are optimized away
by the compiler. Try explicitly adding a prototype declaring the variable
as extern.

#include "stdafx.h"

using namespace System;
using namespace System::Reflection;

const int test = 10023;

Try:
extern const int test;
const int test = 10023;

int main(array<System::String ^> ^args)
{
Module^ mod = Assembly::GetExecutingAssembly()->GetModules()[0];
Console::WriteLine( mod->Name );
FieldInfo^ info = mod->GetField("test",
BindingFlags:ublic|
BindingFlags::NonPublic|
BindingFlags::Instance|
BindingFlags::Static|
BindingFlags::FlattenHierarchy);
if ( info ) {
Console::WriteLine( "Found: " + info->Name );
}
array<Type^>^t = mod->FindTypes( Module::FilterTypeName, "t*" );
for( int i = 0; i < t->Length; i++ ) {
Console::WriteLine( t->Name );
}
Console::ReadLine();
return 0;
