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

Q2: vb.net 获取局域网计算机的当前用户名和计算机型号等信息

Dim sJM As String

Dim sMC As String

Dim sIP As String

Dim s As String

s = String(128, Chr(0))

GetComputerName s, Len(s)

s = UCase(Left(s, InStr(1, s, Chr(0)) - 1))

sJM = s'计算机名称

s = String(128, Chr(0))

GetUserName s, Len(s)

s = UCase(Left(s, InStr(1, s, Chr(0)) - 1))

sMC = s‘当前用户名称

End Sub

'用这种方法在远程获得再发回本机就可以吧

'取计算机型号暂时不会

Q3: vb.net 获取指定网卡的网络连接状态

.net不能获得【指定】网卡vb.net读取网卡型号的信息vb.net读取网卡型号，给个思路，先遍历所有网卡，然后找到你需要vb.net读取网卡型号的的那个网卡的信息。

Q4: 电脑有两张网卡。如何用vb.net分别获取网卡的IP?求大神明路！

'要使得引用System.Management有效vb.net读取网卡型号，先通过菜单

'[项目]--[添加引用]vb.net读取网卡型号，在“.Net”选项卡里vb.net读取网卡型号，选择“System.Management”vb.net读取网卡型号，单击[确定]

Imports System.Management

Public Class Form1

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim MySearcher As New ManagementObjectSearcher("SELECT * FROM Win32_NetworkAdapterConfiguration")

For Each MySearcherObj As ManagementObject In MySearcher.Get

If CBool(MySearcherObj("IPEnabled")) Then

MsgBox(MySearcherObj("IPAddress")(0))

End If

Next

End Sub

End Class

Q5: 求大神指点 vb.net 怎么获取 所有网卡的 描述呢? vbs 的也可以

Private Sub GetMyIP()

        Dim strComputer As String

        Dim objWMI As Object

        Dim colIP As Object

        Dim IP As Object

        Dim I As Integer

        strComputer = "."

        objWMI = GetObject("winmgmts://"  strComputer  "/root/cimv2")

        colIP = objWMI.ExecQuery _

        ("Select * from Win32_NetworkAdapterConfiguration where IPEnabled=TRUE")

        For Each IP In colIP

            If Not IsNothing(IP.IPAddress) Then

                For I = LBound(IP.IPAddress) To UBound(IP.IPAddress)

                    MsgBox("IP 地址:"  IP.IPAddress(I)  Chr(10)  _

                    "网卡类型:"  IP.Description(I)  Chr(10)  _
