WCHAR如何转string

WCHAR转换为string可以通过使用WideCharToMultiByte函数来实现。这个函数可以将宽字符字符串转换为多字节字符串。下面是一个示例代码，演示了如何将WCHAR转换为string：

#include <string>
#include <Windows.h>

std::string WCHARToString(const wchar_t* pwszSrc) {
    int nLen = WideCharToMultiByte(CP_ACP, 0, pwszSrc, -1, NULL, 0, NULL, NULL);
    if (nLen <= 0) return std::string("");

    char* pszDst = new char\[nLen\];
    if (NULL == pszDst) return std::string("");

    WideCharToMultiByte(CP_ACP, 0, pwszSrc, -1, pszDst, nLen, NULL, NULL);
    pszDst\[nLen - 1\] = 0;

    std::string strTmp(pszDst);
    delete\[\] pszDst;

    return strTmp;
}

你可以使用上述函数将WCHAR转换为string。只需将WCHAR字符串作为参数传递给WCHARToString函数，它将返回相应的string类型结果。
