Compiler Error C3255

'value type' : cannot dynamically allocate this value type object on native heap

Remarks

Instances of a value type (see Classes and Structs) that contain managed members can be created on the stack but not on the heap.

Example

The following example generates C3255:

// C3255.cpp
// compile with: /clr
using namespace System;
value struct V {
   Object^ o;
};

value struct V2 {
   int i;
};

int main() {
   V* pv = new V;   // C3255
   V2* pv2 = new V2;
   V v2;
}
