获取重载静态函数的地址[重复](Getting the address of an overloaded static function [duplicate])

 
 
 可能重复： 
 如何指定指向重载函数的指针？ 
 
 
 我有一个库，其类定义为： 
 
struct ClassA
{
    static ClassA foo(long);
    static ClassA foo(double);
}
 
 我需要获取这两个函数的地址。 我正在尝试的代码给出错误C2440：无法从'overloaded-function'转换为'...' 
 
ns::ClassA (ns::ClassA::*ClassA_foo1)(long) = &ns::ClassA::foo;
ns::ClassA (ns::ClassA::*ClassA_foo2)(double) = &ns::ClassA::foo;
 
 我认为它们可能是静态的，但在返回类型之前或之后放置静态会产生相同的错误。

I have a library which has a class defined as:
 
struct ClassA
{
    static ClassA foo(long);
    static ClassA foo(double);
}
 
I need to get the addresses of both of those functions. The code I am currently trying gives error C2440: cannot convert from 'overloaded-function' to '...'
 
ns::ClassA (ns::ClassA::*ClassA_foo1)(long) = &ns::ClassA::foo;
ns::ClassA (ns::ClassA::*ClassA_foo2)(double) = &ns::ClassA::foo;
 
I thought it might be the fact that they are static, but placing static either before or after the return type gives the same error.
