Help me
check this link it has some similar information regarding enabling and disabling LAN connection in c#.... And if you are using DHCP then follow this link
I tried this link.. (i.e) ReleaseDHCPLease, but it didn't work!!
Can you give your code?
Can you give your code?
ManagementClass objMC = new ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection objMOC = objMC.GetInstances();
foreach (ManagementObject objMO in objMOC)
{
objMO.InvokeMethod("ReleaseDHCPLease", null, null);
}
Can you give the code to connect with LAN? if you have otherwise tell the main success scenario of your project
Actually What i need to do is to Disconnect Internet connection of single system temporarily.. Since i have connected three systems through LAN,I guess that disconnecting the LAN connection will disconnect internet connection of that particular system!!!
Am I clear?
To tell in simple words, unplugging the LAN Wire manually will disconnect internet. I need to do this through program!!!
It contains an assembly class library and a test project which includes that assembly class just check and if working add the dll of assembly class library in your project and use its funcitons

I could not get it. Can you help me??
if you need to disable your internet connection the simplest way is to change your gateway
to some ip that doesn't provide the functionality.
ex:
your curent settings:
your modified setting:
this method still lets u use the local network. if you want to disable that too just change your ip address too.
sample code to change ip address
public void setIP(string ip_address, string subnet_mask)
{
ManagementClass objMC = new ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection objMOC = objMC.GetInstances();
foreach (ManagementObject objMO in objMOC)
{
if ((bool)objMO["IPEnabled"])
{
try
{
ManagementBaseObject setIP;
ManagementBaseObject newIP =
objMO.GetMethodParameters("EnableStatic");
newIP["IPAddress"] = new string[] { ip_address };
newIP["SubnetMask"] = new string[] { subnet_mask };
setIP = objMO.InvokeMethod("EnableStatic", newIP, null);
}
catch (Exception)
{
throw;
}
}
}
}
sample code to change gateway
public void setGateway(string gateway)
{
ManagementClass objMC = new ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection objMOC = objMC.GetInstances();
foreach (ManagementObject objMO in objMOC)
{
if ((bool)objMO["IPEnabled"])
{
try
{
ManagementBaseObject setGateway;
ManagementBaseObject newGateway =
objMO.GetMethodParameters("SetGateways");
newGateway["DefaultIPGateway"] = new string[] { gateway };
newGateway["GatewayCostMetric"] = new int[] { 1 };
setGateway = objMO.InvokeMethod("SetGateways", newGateway, null);
}
catch (Exception)
{
throw;
}
}
}
}
Thanks a lot pitic.. But i solved it by myself. I used a VB program.
Public Shared Sub ToggleWirelessConnection()
For Each verb As Shell32.FolderItemVerb In WirelessConnectionFolderItem.Verbs
If verb.Name = "En&able" OrElse verb.Name = "Disa&ble" Then
verb.DoIt()
Exit For
End If
Next
Threading.Thread.Sleep(1000)
End Sub
