如何绑定到vector <> :: at？(How to bind to vector<>::at?)

 在Visual C ++ 2013中，以下代码给出了一个“模糊调用”编译错误： 
 
typedef vector<int> V;
V v;
auto b1 = bind(&V::at, &v);
 
 现在我已经四处搜索，发现我应该投射到我想要的签名。 所以我这样做： 
 
auto b2 = bind(static_cast<int(V::*)(V::size_type)>(&V::at), &v);
 
 现在，错误是： 
 
'static_cast' : cannot convert from 'overloaded-function' to 'int (__thiscall std::vector<_Ty>::* )(unsigned int)'
 
 我怎么能正确地做到这一点？ 

In Visual C++ 2013 the following code gives me an "ambiguous call" compile error:
 
typedef vector<int> V;
V v;
auto b1 = bind(&V::at, &v);
 
Now I have searched around and found I should be casting to the signature I want. So I do this:
 
auto b2 = bind(static_cast<int(V::*)(V::size_type)>(&V::at), &v);
 
Now, the error is:
 
'static_cast' : cannot convert from 'overloaded-function' to 'int (__thiscall std::vector<_Ty>::* )(unsigned int)'
 
How can I do it correctly?
