用vb.net如何取得mac地址？
刚刚我自己写了一段 是引用System.net 来做的 我不喜欢用WMI 主要是查出来的信息不准确，下面我附上源码 希望可以加分给我
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 +
"网络连接：" + NetWork.Name + Environment.NewLine +
"网卡序列号：" + NetWork.Id + Environment.NewLine +
"网络类型：" + NetWork.NetworkInterfaceType.ToString() + Environment.NewLine +
"网络速度：" + (NetWork.Speed / 1000000).ToString() + "MB" + Environment.NewLine
Next
End If
End Sub
End Class

Q3: VB.NET 获取网关IP MAC地址
我找了一些C# 的VB。NET 貌似很少不过都是。NET 平台。你看看吧都应该通用的。
添加对System.Management的引用
using System.Management;
。。。
//获取IP,子网掩码(subnet mask)和默认网关
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]);
}
}

Q4: 怎么用vb.net获取无线网络的MAC地址
你可以使用WMI来获取MAC ID。。加上一些特定的条件也可以实现获取WLAN MAC_ID
Q5: VB.NET 如何修改mac地址
首先MAC地址在网卡中是固定的，可以修改，但通常不进行修改，通过vb.net修改的方式并不清楚但在XP或者W2000里面可以通过更改注册表进行修改
