用vb.net如何取得mac地址？

这是C#的，你可以转换一下

using System.Management;

//获取网卡的系列号

private static string GetMacAddress()

{

string ret = "";

try

{

ManagementClass cimobject = new ManagementClass("Win32_NetworkAdapterConfiguration");

ManagementObjectCollection moc = cimobject.GetInstances();

if (moc.Count == 0)

return "";

else

{

foreach (ManagementObject mo in moc)

{

if ((bool)mo["IPEnabled"] == true)

{

ret = (string)mo.Properties["MacAddress"].Value;

break;

}

}

}

}

catch

{

ret = "";

}

return ret;

}

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

vb.net怎么获取网卡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

End Function

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]);

}

}
