Is there an equivalent to the C# “var” keyword in C++/CLI?

Question

In C#, I like the var keyword for situations like this:

var myList = new List<MyType>();

Is there any equivalent in C++/CLI, or do I have to repeat the type name everytime just like this:

List<MyType ^>^ myList = gcnew List<MyType ^>();

Could not find an explicit statement in the docs or by Google so far. I am using Visual Studio 2008.

Answer 1

In Visual Studio 2008 there is no such equivalent. However with Visual Studio 2010 you can use the auto keyword to implement var like semantics in C++. I know this works with non-managed C++ and I'm fairly certain it works for C++/CLI as well.

Answer 2

I know that type inference is envisioned in the C++1x standard:

auto someStrangeCallableType = boost::bind(&SomeFunction, _2, _1, someObject);
auto otherVariable = 5;

Currently, AFAIK, there is no equivalent.

Answer 3

C++ has typedef. Just alias those hairy types with a typedef, and use the friendly name.

No, there's no "var" keyword. Vaguely recall there's something to that effect in boost.

Answer 4

C++0x is going to have an auto keyword: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2004/n1705.pdf
