'member': only static data members can be initialized inside a ref class or value type

A data member inside a managed type cannot be initialized unless it is static.

The following sample generates C3845:

// C3845.cpp
// compile with: /clr
using namespace System;

ref class A {
public:
   const Int32 n = 7;   // C3845
};

Possible resolution:

// C3845b.cpp
// compile with: /clr /c
using namespace System;

ref class A {
public:
   static Int32 n = 7;
};

Managed Extensions for C++

The following sample generates C3845:

// C3845c.cpp
// compile with: /clr:oldSyntax
#using <mscorlib.dll>
using namespace System;

__gc class A {
public:
   const Int32 m = 7;   // C3845
};

Possible resolution:

// C3845d.cpp
// compile with: /clr:oldSyntax /c
#using <mscorlib.dll>
using namespace System;

__gc class A {
public:
   static Int32 n = 7;
};
