c++ - 如何在Visual C++中将WORD类型转换为字符串

Question

谁能解释一下如何在 C++ 中将 WORD 转换为字符串？

  typedef struct _appversion
    {
        WORD            wVersion;  
        CHAR            szDescription[DESCRIPTION_LEN+1];
    } APPVERSION;

    // Some code
    APPVERSION AppVersions;

    // At this point AppVersions structure is initialized properly.

    string wVersion;

    wVersion = AppVersions.wVersion; // Error

// Error    1   error C2668: 'std::to_string' : ambiguous call to overloaded function   
    wVersion = std::to_string((unsigned short)AppVersions.wVersion); 

Answer 1

一个WORD在 Visual C++ 上下文中是 unsigned short 的类型定义.

所以你可以使用std::to_string对于这个任务:

 wVersion = std::to_string(AppVersions.wVersion); 

编辑: 显然 Visual Studio 2010 不完全支持 C++11 功能，请使用 std::stringstream相反:

std::stringstream stream;
stream <<AppVersions.wVersion;
wVersion  = stream.str();

确保包含 <sstream>
