Error C2327

[kevin_g_frey]

Hello All,

I have effectively the following (part of a much bigger header):

namespace X
{

namespace Y
{

__gc public class EnvironmentList
{
// rest of declaration
};

__gc public class AnotherClass
{
public:
__property EnvironmentList* get_EnvironmentList( ); // **!**

private:
EnvironmentList* p_EnvironmentList; // **!**
};

} // namespace Y

} // namespace X

When I compile this the two lines marked **!** produce error C2327
saying that "X::Y::AnotherClass::EnvironmentList" is not a type name,
static, or enumerator.

I can get around this by fully qualifying the type (eg.
X::Y::EnvironmentList) in each case, but would prefer not to do so
because I have other cases which work perfectly (different class names
however).

I thought this might be due to an ambiguity with an existing class
named EnvironmentList in another namespace, but cannot find any
reference to such in MSDN. In addition, I tried a simple test
application to show how CL reports ambiguities and it seems to report
them correctly.

Any help appreciated...

You're problem is that the property is called the same as the type, so by
the time the compiler parses the property declaration, it has introduced a
new name "EnvironmentList - the property", so when it parses the field
member declaration, it doesn't know whether you're referencing the property
or the type.

The fix is actually quite simple: Just move the field declaration before the
property declaration (or rename the property, but that's not needed here):

__gc public class AnotherClass
{
private:
EnvironmentList* p_EnvironmentList; // **!**
public:
__property EnvironmentList* get_EnvironmentList( ); // **!**

};

Thanks, Tom. I have in fact chosen to rename the property (it actually
makes it more consistent with some others we have). But at least I now
know what the problem is!
