我正在VB.Net中編寫一個Windows Forms應用程序,它將(除其他外)更改IP地址,默認網關,子網掩碼並將IP地址設置爲靜態只有Winfows 7。 Sysprep沒有被使用。我搜索了Google,只有2個選項。我不相信第一種解決方案會適用於我,因爲我不一定知道連接的名稱。它使用netsh來更改IP設置。我打算給這個例子的鏈接,但我不能發佈超過2個鏈接...在VB.Net中更改IP地址
第二個解決方案顯示在this link (the VB.Net version)和原始代碼是here (the C# version)。這個解決方案使用WMI,我真的不知道那麼多。
當我調試代碼,看看一切代碼似乎被正確執行,但IP地址仍然設置爲DHCP和所有其他設置仍然是相同的。所以,基本上,是什麼給了?爲什麼這段代碼似乎不起作用?
這是我的代碼。我只是做了一些改動:
'Changed the 3 IPs below
Dim IPAddress As String = "192.168.1.105"
Dim SubnetMask As String = "255.255.252.0"
Dim Gateway As String = "192.168.1.100"
Dim objMC As ManagementClass = New ManagementClass("Win32_NetworkAdapterConfiguration")
Dim objMOC As ManagementObjectCollection = objMC.GetInstances()
For Each objMO As ManagementObject In objMOC
If (Not CBool(objMO("IPEnabled"))) Then
Continue For
End If
Try
Dim objNewIP As ManagementBaseObject = Nothing
Dim objSetIP As ManagementBaseObject = Nothing
Dim objNewGate As ManagementBaseObject = Nothing
objNewIP = objMO.GetMethodParameters("EnableStatic")
objNewGate = objMO.GetMethodParameters("SetGateways")
'Set DefaultGateway
objNewGate("DefaultIPGateway") = New String() {Gateway}
objNewGate("GatewayCostMetric") = New Integer() {1}
'Set IPAddress and Subnet Mask
objNewIP("IPAddress") = New String() {IPAddress}
objNewIP("SubnetMask") = New String() {SubnetMask}
objSetIP = objMO.InvokeMethod("EnableStatic", objNewIP, Nothing)
objSetIP = objMO.InvokeMethod("SetGateways", objNewGate, Nothing)
'Changed this line so I could see if it was executing all of the way
MessageBox.Show("Updated IPAddress, SubnetMask and Default Gateway!")
Catch ex As Exception
MessageBox.Show("Unable to Set IP : " & ex.Message)
End Try
Next objMO

*不*忽視的InvokeMethod()的返回值,它會提供一個錯誤代碼,如果該方法失敗。 – 2013-02-08 17:32:57
