wchar to char转换

//将string转换成wstring wstring StringToWString(const string& str) { wstring result; //获取缓冲区大小，并申请空间，缓冲区大小按字符计算 int len = ::MultiByteToWideChar(CP_ACP, 0, str.c_str(), str.size(), NULL, 0); TCHAR* buffer = new TCHAR[len + 1]; //多字节编码转换成宽字节编码 ::MultiByteToWideChar(CP_ACP, 0, str.c_str(), str.size(), buffer, len); buffer[len] = '/0'; //添加字符串结尾 //删除缓冲区并返回值 result.append(buffer); delete[] buffer; return result; } //将wstring转换成string string WstringToString(const wstring& wstr) { string result; //获取缓冲区大小，并申请空间，缓冲区大小事按字节计算的 int len = ::WideCharToMultiByte(CP_ACP, 0, wstr.c_str(), wstr.size(), NULL, 0, NULL, NULL); char* buffer = new char[len + 1]; //宽字节编码转换成多字节编码 ::WideCharToMultiByte(CP_ACP, 0, wstr.c_str(), wstr.size(), buffer, len, NULL, NULL); buffer[len] = '/0'; //删除缓冲区并返回值 result.append(buffer); delete[] buffer; return result; }
