Cast list to ICollection

Using make_collection<>() to create ICollection from vector

#include <cliext/adapter>

return *this;
}
~MyClass() { }
bool operator<(const MyClass^ rhs){
return (Name->CompareTo(rhs->Name) < 0);
}
bool operator==(const MyClass^ rhs){
return (Name->Equals(rhs->Name));
}

pets.push_back(gcnew MyClass("A"));

ICollection<MyClass^>^ icMyClasss = make_collection(pets.begin() + 1,pets.end() - 1);
for each (MyClass^ pet in icMyClasss)
