std::wstring 转std::string 文心快码BaiduComate 在C++中,将std::wstring转换为std::string时,我们需要考虑编码方式,因为std::wstring使用wchar_t类型来存储宽字符,而std::string使用char类型来存储单字节字符。以下是一个详细的步骤说明和相应的代码示例: 1. 确定转换编码方式 在Windows平台上,常用的编码方式有CP...

第一种方法:调用WideCharToMultiByte()和MultiByteToWideChar(),代码如下(关于详细的解释,可以参考《windows核心编程》): #include <string> #include <windows.h> using namespace std; //Converting a WChar string to a Ansi string std::string WChar2Ansi(LPCWSTR pwszSrc) { int nLen = WideCharToMultiByte(CP...
