How to disable/enable network connection in c#

by

Found this thread while searching for the same thing, so, here is the answer 🙂

The best method I tested in C# uses WMI.

http://www.codeproject.com/KB/cs/EverythingInWmi02.aspx

Win32_NetworkAdapter on msdn

C# Snippet : (System.Management must be referenced in the solution, and in using declarations)

SelectQuery wmiQuery = new SelectQuery("SELECT * FROM Win32_NetworkAdapter WHERE NetConnectionId != NULL");
ManagementObjectSearcher searchProcedure = new ManagementObjectSearcher(wmiQuery);
foreach (ManagementObject item in searchProcedure.Get())
{
    if (((string)item["NetConnectionId"]) == "Local Network Connection")
    {
       item.InvokeMethod("Disable", null);
    }
}
