剛剛我自己寫了壹段?是引用System.net?來做的我不喜歡用WMI?主要是查出來的信息不準確，下面我附上源碼?希望可以加分給我
Imports?System.Net
Imports?System.Net.NetworkInformation
Public?Class?Form1
Private?Sub?btnGetMac_Click(ByVal?sender?As?System.Object,?ByVal?e?As?System.EventArgs)?Handles?btnGetMac.Click
Dim?NetworkInterfaces()?As?NetworkInterface
NetworkInterfaces?=?NetworkInterface.GetAllNetworkInterfaces()
If?NetworkInterfaces.Length?>?0?Then
For?Each?NetWork?In?NetworkInterfaces
txtMac.Text?=?txtMac.Text?+
"MAC地址："?+?NetWork.GetPhysicalAddress().ToString()?+?Environment.NewLine?+
"網絡連接："?+?NetWork.Name?+?Environment.NewLine?+
"網卡序列號："?+?NetWork.Id?+?Environment.NewLine?+
"網絡類型："?+?NetWork.NetworkInterfaceType.ToString()?+?Environment.NewLine?+
"網絡速度："?+?(NetWork.Speed?/?1000000).ToString()?+?"MB"?+?Environment.NewLine
Next
End?If
End?Sub
End?Class
