declaration' : template parameter 'identifier' is ambiguous
The compiler cannot determine the type of a template argument.
The following sample generates C2782:
// C2782.cpp
template<typename T>
void f(T, T) {}
int main() {
f(1, 'c'); // C2782
// try the following line instead
// f<int>(1, 'c');
}
C2782 can also occur when using generics:
// C2782b.cpp
// compile with: /clr
generic<typename T> void gf(T, T) { }
int main() {
gf(1, 'c'); // C2782
// try the following line instead
// gf<int>(1, 'c');
}
