Compiler Error C2681

'type' : invalid expression type for name

Remarks

A casting operator tried to convert from an invalid type. For example, if you use the dynamic_cast operator to convert an expression to a pointer type, the source expression must be a pointer.

Example

The following example generates C2681:

// C2681.cpp
class A { virtual void f(); };

void g(int i) {
    A* pa;
    pa = dynamic_cast<A*>(i);  // C2681
}
