Compiler Error C3181
Visual Studio 2010
'type' : invalid operand for operator
An invalid parameter was passed to the __typeof or typeid operator. The parameter must be a managed type.
Note that the compiler uses aliases for native types that map to types in the common language runtime.
The following sample generates C3181:
// C3181a.cpp
// compile with: /clr
using namespace System;
int main() {
Type ^pType1 = interior_ptr<int>::typeid; // C3181
Type ^pType2 = int::typeid; // OK
}
The following sample generates C3181:
// C3181b.cpp
// compile with: /clr:oldSyntax
#using <mscorlib.dll>
using namespace System;
int main() {
Type *pType1 = __typeof(int __gc*); // C3181
Type *pType2 = __typeof(int*); // OK
}
