VC中支持中文的字符串比较函数

VS2008开发环境，多字符集和UNICODE字符集都可用。

WCHAR * mbcsToUnicode(const char *zStr)

{

    int nByte;

    WCHAR *zMbcsStr;

    int codepage = AreFileApisANSI() ? CP_ACP : CP_OEMCP;

    nByte = MultiByteToWideChar(codepage, , zStr, -, NULL,)*sizeof(WCHAR);

    zMbcsStr = (WCHAR*)malloc( nByte*sizeof(zMbcsStr[]) );

    if( zMbcsStr== )

        {

        return ;

    }

    nByte = MultiByteToWideChar(codepage, , zStr, -, zMbcsStr, nByte);

    if( nByte== )

        {

        free(zMbcsStr);

        zMbcsStr = ;

    }

    return zMbcsStr;

}

BOOL CompareStr(CStringA S1, CStringA S2)

{

    WCHAR* wa;

    WCHAR* wb;

    wa = mbcsToUnicode(S1.GetBuffer());

    wb = mbcsToUnicode(S2.GetBuffer());

    return CompareStringW(LOCALE_USER_DEFAULT, NORM_IGNORECASE, (LPCWSTR)wa, wcslen(wa), (LPCWSTR)wb, wcslen(wb)) - CSTR_EQUAL == ;

}
