Releasing and Renewing your DHCP-based IP Address

c#, network-programming

Solution

You could use WMI, but its much simpler to just do it using `System.Diagnostics.Process`

Here is a WMI solution anyway:

ManagementClass objMC = new ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection objMOC = objMC.GetInstances();

foreach (ManagementObject objMO in objMOC)
{
    //Need to determine which adapter here with some kind of if() statement
    objMO.InvokeMethod("ReleaseDHCPLease", null, null);
    objMO.InvokeMethod("RenewDHCPLease", null, null); 
}

Problem

Using C# how can I release and renew my DHCP-based IP Address? At the moment I am using the process method to use these DOS commands: ``` ipconfig /release ``` and ``` ipconfig /renew ``` Is there a more managed approach in C# for this?
