初步说明：string_algo与std::wstring的工作正常，当然，如果需要，我可以（并做）将CString对象首先转换为std :: wstring string_algo的算法。如果我可以直接放入CString对象，那将是非常好的 - 与现有代码的集成将更容易！
我想做什么：
CString in = ...;
const CString out = boost::replace_last_copy(in, L"SEARCH", L"REPLACE");
作为suggested here，我尝试另外包含boost/range/mfc.hpp来Boost.Range adapted to MFC。 （虽然我不太看this header看起来它似乎对CString没有任何作用，只对集合类有用。）
使用Visual Studio 2005提升1.44.0
测试代码如下所示：
#include "stdafx.h"
#include <iostream>
#include <boost/range/mfc.hpp>
#include <boost/algorithm/string.hpp>
void f(CString const& input) {
CString out = boost::replace_last_copy(input, L"FROM", L"TO");
std::wcout << out << "\n";
}
我得到的错误如下：

答案 0 :(得分：0)
尝试将CString替换为CStringW，以防CString映射到CStringA。
确切的错误代码怎么样，标题中的哪一行？您可以尝试在本地代码中替换相同的错误吗？
