IpHlpApi.GetAdaptersAddresses() GatewayAddresses Member is always zero

[shouhujishu]

IpHlpApi.GetAdaptersAddresses(Vanara.PInvoke.IpHlpApi.GetAdaptersAddressesFlags.GAA_FLAG_INCLUDE_ALL_INTERFACES);
The gateway list is always zero when iterating over the results
os: windows11 23H2
Thanks for the help

That is odd. I'm running the same OS ver and get a list of like 50 interfaces. Try some different flag values and see if the absence remains.

Thank you for your reply. I have tried to switch different flags, and the result is normal. Only the GatewayAddresses enumeration is always empty.

Are you running your code as 32 or 64 bit? Can you try with second param as , ADDRESS_FAMILY.AF_UNSPEC?
