怎么用vb.net獲取無線網(wǎng)絡的MAC地址

你可以使用WMI來獲取MAC ID。。加上一些特定的條件也可以實現(xiàn)獲取WLAN MAC_ID

vb.net怎么獲取網(wǎng)卡MAC地址？

Public Function EnumNetworkAdapters() As String

Try

Dim query As System.Management.ManagementObjectSearcher = New System.Management.ManagementObjectSearcher("SELECT * FROM Win32_NetworkAdapterConfiguration")

Dim queryCollection As System.Management.ManagementObjectCollection = query.Get()

Dim mo As New System.Management.ManagementObject

For Each mo In queryCollection

If IsDBNull(mo.Item("Description")) = False Then

EnumNetworkAdapters = mo.Item("Description") "|||"

End If

If IsDBNull(mo.Item("macaddress")) = False Then

If mo.Item("macaddress") "" Then

EnumNetworkAdapters = mo.Item("macaddress") "|||"

End If

End If

If IsDBNull(mo.Item("IPAddress")) = False Then

Dim temp As String

temp = Join(mo.Item("IPAddress"), ".")

If temp "" Then

EnumNetworkAdapters = temp "|||"

End If

End If

Next

Catch err A* **ception

EnumNetworkAdapters = err.Message err.StackTrace

End Try

VB.NET 如何修改mac地址

首先MAC地址在網(wǎng)卡中是固定的，可以修改，但通常不進行修改，通過vb.net修改的方式并不清楚但在XP或者W2000里面可以通過更改注冊表進行修改

用vb.net如何取得mac地址？

剛剛我自己寫了一段??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(wǎng)絡連接："?+?NetWork.Name?+?Environment.NewLine?+

"網(wǎng)卡序列號："?+?NetWork.Id?+?Environment.NewLine?+

"網(wǎng)絡類型："?+?NetWork.NetworkInterfaceType.ToString()?+?Environment.NewLine?+

"網(wǎng)絡速度："?+?(NetWork.Speed?/?1000000).ToString()?+?"MB"?+?Environment.NewLine

Next

End?If

VB.NET 獲取網(wǎng)關IP MAC地址

我找了一些C# 的VB。NET 貌似很少不過都是。NET 平臺。你看看吧都應該通用的。

添加對System.Management的引用

using System.Management;

。。。

//獲取IP,子網(wǎng)掩碼(subnet mask)和默認網(wǎng)關

ManagementClass mc = new ManagementClass( "Win32_NetworkAdapterConfiguration ");

ManagementObjectCollection nics = mc.GetInstances();

foreach(ManagementObject nic in nics)

{

if(Convert.ToBoolean(nic[ "ipEnabled "]) == true)

{

Console.WriteLine((nic[ "IPAddress "] as String[])[0]);

Console.WriteLine((nic[ "IPSubnet "] as String[])[0]);

Console.WriteLine((nic[ "DefaultIPGateway "] as String[])[0]);

}

}

獲取硬件信息源代碼：

獲取硬件信息演示程序：

漢化

利用using System.Management類來獲取相應的硬件知識

其實這類東西很容易找到答案的，方法非常多，最常見的API模式，你去搜索吧，保證一把一把的
