除了名称之外，我想通过适配器的描述更改Mac地址。因此，我需要修改此代码，以便在找不到匹配的名称时，它会回退到根据描述更改mac。
这是一个示例适配器：
名称：本地连接
描述：Marvell Yukon 88E8055 PCI-E千兆以太网控制器
不幸的是，作为一名Java开发人员，我对C ++的经验有限，所以非常感谢任何帮助。

这是GetAdaptersInfo的C示例，它打印出每个适配器名称和描述（您可以通过在匹配时调用SetMAC轻松地使其适应您的代码）：
VOID EnumerateNetworkAdapters(VOID)
{
ULONG len = 0;
if (ERROR_BUFFER_OVERFLOW == GetAdaptersInfo(NULL, &len))
{
IP_ADAPTER_INFO *ipai;
ipai = malloc(len);
if (NO_ERROR == GetAdaptersInfo(ipai, &len))
{
IP_ADAPTER_INFO *p = ipai;
do
{
printf("name=%s description=%s\n", p->AdapterName, p->Description);
}
while (p = p->Next);
}
free(ipai);
}
}

通过在调用PIP_ADAPTER_ADDRESSES::FriendlyName之前比较说明（PIP_ADAPTER_ADDRESSES::Description），使用GetAdaptersAddresses获取适配器名称（SetMAC()）。示例可以在上面的MSDN链接中找到。
