Compiler Error C3145

'object' : global or static variable may not have managed or WinRT type 'type'

Remarks

You can only define CLR or WinRT objects within function scope.

Examples

The following example generates C3145 and shows how to fix it:

// C3145.cpp
// compile with: /clr
using namespace System;
ref class G {};

G ^ ptr;   // C3145
G ^ ptr2 = gcnew G;   // C3145

ref class GlobalObjects {
public:
   static G ^ ptr;   // OK
   static G ^ ptr2 = gcnew G;   // OK
};

int main() {
   G ^ ptr;   // OK
   G ^ ptr2 = gcnew G;   // OK
}

The following example generates C3145:

// C3145b.cpp
// compile with: /clr
ref class MyClass {
public:
   static int data;
};

interior_ptr<int> p = &(MyClass::data);   // C3145

void Test(interior_ptr<int> x) {}

int main() {
   MyClass ^ h_MyClass = gcnew MyClass;
   interior_ptr<int> p = &(h_MyClass->data);
}
