There is no native support in .NET, you need to invoke the win api, specifically wininet.dll and invoke InternetGetConnectedState function. You can use the following link for with a sample code. Code is in VB, but you can easily convert it to c#.

Answer 2

On the commandline (DOS) you can use the netsh command.

Instructions: 1) Get the mobile interface and note the name

netsh mbn show interface

Output:

There is 1 interface on the system:

Name               : Mobiel 5
Description        : Sierra Wireless EM7345 4G LTE
GUID               : xxx
Physical Address   : xxx
State              : Not connected
Device type        : Mobile Broadband device is embedded in the system
Cellular class     : GSM
Device Id          : xxx
Manufacturer       : Sierra Wireless Inc.
Model              : Sierra Wireless EM7345 4G LTE
Firmware Version   : FIH7160_V1.2_WW_01.1442.11

Roaming            : Yes
Signal             : 74%
RSSI / RSCP        : 23 (-67 dBm)

2) Get the connection profiles for the interface (on my system the name is "mobiel 5"

netsh mbn show profiles interface="mobiel 5"

Output

Profiles on interface Mobiel 5:
-------------------------------------
    {3623E7AB-E116-47E6-8A9B-FCC1ADBE568E}
    {F4E77FAE-D4FD-4196-86CA-852EFE8A9154}
    !!##MBIMModemProvisionedContextInternetProfile##8935299564103228197

3) Connect using the interface and profile name

netsh mbn connect interface="mobiel 5" connmode=name name="{F4E77FAE-D4FD-4196-86CA-852EFE8A9154}"

4) Disconnect using the interface name

netsh mbn disconnect interface="mobiel 5"

This works on Windows 10
