vb.net筆記本讀不出網(wǎng)卡地址

出現(xiàn)這樣的原因，大部分是由于 無線網(wǎng)卡沒有安裝到位，接觸不良造成的。

用vb.net實現(xiàn)網(wǎng)絡(luò)通信

用 vb.net socket通信

Dim th As Threading.Thread

2 Dim tcpl As System.Net.Sockets.TcpListener

4 Private Sub Form1_Load()Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

5 th = New System.Threading.Thread(New System.Threading.ThreadStart(AddressOf MyListen))

6 th.Start()

7 End Sub

9 Public Sub SendMessage()Sub SendMessage(ByVal IP As String, ByVal SendMsg As String)

10 Try

11 If IP "" Then

12 Dim tcpc As New System.Net.Sockets.TcpClient(IP, 5656)

13 Dim tcpStream As Net.Sockets.NetworkStream = tcpc.GetStream

14 Dim reqStream As New IO.StreamWriter(tcpStream)

15 reqStream.Write(SendMsg)

16 reqStream.Flush()

17 tcpStream.Close()

18 tcpc.Close()

19 End If

20 Catch ex As Exception

21 MsgBox(ex.Message.ToString)

22 End Try

23 End Sub

24 Private Sub MyListen()Sub MyListen()

25 Try

26 Dim ipAddress As System.Net.IPAddress = System.Net.Dns.Resolve(System.Net.Dns.GetHostName).AddressList(0)

27 tcpl = New System.Net.Sockets.TcpListener(ipAddress, 5656)

28 tcpl.Start()

29 While True

30 Dim s As System.Net.Sockets.Socket = tcpl.AcceptSocket()

31 Dim MyBuffer(1024) As Byte

32 Dim i As Integer

33 i = s.Receive(MyBuffer)

34 If i 0 Then

35 Dim lstrRec As String

36 Dim j As Integer

37 For j = 0 To i - 1

38 TextBox1.Text += Chr(MyBuffer(j)) ","

39 Next

40 End If

41 End While

42 Catch ex As Exception

43 MsgBox(ex.Message.ToString)

44 End Try

45 End Sub

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

48 SendMessage("192.168.0.61", TextBox2.Text)

vb.net 檢測網(wǎng)絡(luò)連接

既然從網(wǎng)上找的實例沒問題，也許就是調(diào)用的時候沒出來或者在檢測網(wǎng)卡當(dāng)中出現(xiàn)了問題。

vb.net 獲取指定網(wǎng)卡的網(wǎng)絡(luò)連接狀態(tài)

.net不能獲得【指定】網(wǎng)卡的信息，給個思路，先遍歷所有網(wǎng)卡，然后找到你需要的的那個網(wǎng)卡的信息。
