string转CString

要将string类型转换为CString类型，有两种情况需要考虑：UNICODE和非UNICODE。对于非UNICODE，转换比较简单。你可以使用如下代码进行转换：

string str = "abcde";
CString cstr(str.c_str());

对于UNICODE，需要进行一些额外的转换。你可以使用以下函数将WCHAR转换为ANSI：

string CUtility::WChar2Ansi(LPCWSTR 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 strTemp(pszDst);
    delete[] pszDst;
    return strTemp;
}

然后，你可以按照以下方式转换：

CString cs = _T("abcde");
string str = CGeneralUtility::WChar2Ansi(cs.GetBuffer(cs.GetLength()));

这样就可以将string类型转换为CString类型了。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
