如何檢索計算機的板載以太網MAC地址？

我正在嘗試從計算機檢索板載以太網適配器的MAC地址，以便爲設備生成唯一標識符。以下是我正在使用的方法。如何檢索計算機的板載以太網MAC地址？

NetworkInterface[] ifConfig = NetworkInterface.GetAllNetworkInterfaces(); 
int maxHash = int.MinValue; 
Guid D = Guid.Empty; 

foreach (NetworkInterface net in ifConfig) 
{ 
    if (net.NetworkInterfaceType == NetworkInterfaceType.Ethernet) 
    { 
       if (maxHash < net.GetPhysicalAddress().ToString().GetHashCode()) 
       { 
        maxHash = net.GetPhysicalAddress().ToString().GetHashCode(); 

        ID = new Guid(String.Concat("00000000-0000-0000-0000-", net.GetPhysicalAddress().ToString())); 

       } 
    } 
}

然而，藍牙適配器，適配器虛擬機和其他幾個網絡適配器也是NetworkInterfaceType.Ethernet類型。我怎樣才能獲得板載以太網連接的MAC地址？

做一個包含忽略這些是不可能的。任何幫助將非常感激。

這是一個壞主意。主要是因爲MAC地址不是唯一的。如果考慮（克隆）虛擬機，情況會變得更糟。請參閱https://superuser.com/a/968346 –

@SteffenWinkler，它仍然是事實上的行業標準方法，正如FlexLM所使用的那樣。有什麼選擇？ –

@HarryJohnston正如我所說的你可以生成一個Guid並使用它。你可以做客戶，因爲在現實中碰撞的機會是不存在的。你不能使用任何硬件來識別計算機。其中一個原因是虛擬機，另一個是對計算機的修改，如交換網卡或添加GPU。更改（缺陷）硬件將改變該計算機的ID。 –

作爲選項（不是最好的，但仍然=）） - 您可以嘗試使用度量標準。在大多數情況下，網絡到物理網絡的度量值卡優先級
