How to: Use safe_cast and Generic Types
The following sample shows that safe_cast can perform a downcast with a generic type.
Remarks
// safe_cast_generic_types.cpp
// compile with: /clr
interface struct I {};
generic<class T> where T:I
ref struct Base {
T t;
void test1() {}
};
generic<class T> where T:I
ref struct Derived:public Base <T> {};
ref struct R:public I {};
typedef Base<R^> GBase_R;
typedef Derived<R^> GDerived_R;
int main() {
GBase_R^ br = gcnew GDerived_R();
GDerived_R^ dr = safe_cast<GDerived_R^>(br);
}
