为了将 std::string 转换为 std::wstring,我们需要理解这两种字符串类型之间的主要区别:std::string 使用char 类型来存储字符,而 std::wstring 使用wchar_t 类型。因此,转换过程实际上是从 char 到wchar_t 的转换。以下是将 std::string 转换为 std

CString 相当方便,而 std::string 更兼容STL容器。我正在使用 hash_map 。 However, hash_map does not support CString s as keys, so I want to convert the CString into a std::string .
