Your code is C++/CLI. So, you can use System::Object instead of boost::any.
And also, cliext::vector instead of std::vector. Because native class
(such as boost::any,
std::vector) can't have managed instance.

----
#include <cliext/vector>
Object^ val = dataGridView1[x,y]->Value;
String^ str = val->ToString();
cliext::vector<Object^>^ vec = gcnew cliext::vector<Object^>(n) ;
// or cliext::vector<String^>
(*vec)[x]=str;
