在VB.Net中更改IP地址(Change IP Address in VB.Net)

 我正在VB.Net中编写一个Windows窗体应用程序，它将（除其他外）更改IP地址，默认网关，子网掩码，并仅在Winfows 7的图像上将IP地址设置为静态。 Sysprep未被使用。 我搜索过谷歌，只提出了两个选项。 我不相信第一个解决方案对我有用，因为我不一定知道连接的名称。 它使用netsh来更改IP设置。 我打算给这个例子一个链接，但我不能发布超过2个链接... 
 
 第二个解决方案显示在此链接（VB.Net版本） ，原始代码在此处（C＃版本） 。 这个解决方案使用的WMI我真的不太了解。 
 
 当我调试代码并查看代码似乎正在执行的所有内容但IP地址仍设置为DHCP并且所有其他设置仍然相同。 那么，基本上，是什么给出的？ 为什么这段代码似乎不起作用？ 
 
 这是我的代码。 我只做了一些改动： 
 
    '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

I am writing a Windows Forms App in VB.Net that will (among other things) change the IP Address, Default Gateway, Subnet Mask, and set the IP Address to Static on an image of Winfows 7 only. Sysprep is not being used. I have searched Google and only come up with 2 options. I don't believe the first solution will work for me because I do not necessarily know the name of the connection. It uses netsh to change IP settings. I was going to give a link to this example but I can't post more than 2 links...
 
The second solution is shown at this link (the VB.Net version) and the original code is here (the C# version). This solution uses WMI which I really don't know that much about.
 
When I debug the code and look at everything the code seems to be executing properly but the IP Address is still set to DHCP and all of the other setting are still the same. So, basically, what gives? Why does this code seem to not work?
 
Here is my code. I only made a few changes:
 
    '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
