WebAug 2, 2024 · Unlike standard C++ arrays, managed arrays are implicitly derived from an array base class from which they inherit common behavior. An example is the Sort method, which can be used to order the items in any array. For arrays that contain basic intrinsic types, you can call the Sort method. You can override the sort criteria, and doing so is ... WebEdit: I don't need it to be pointers, but you also can't have arrays of references. I just want to have a less verbose compile time structure of different types. I know the compiler can do temporary lifetime extension in some cases, but it doesn't seem to apply to this case. I want to do this, where Type1 and Type2 are both derived from Base:
