Show which pools a node belongs to. c#

I am trying to figure out the best way to display a report of a node and which pools it belongs to. Does the nodeaddress object know about the pools it is in? I can't seem to find any property that is a list of pools that a node belongs to. Do I need to get the entire list of all the pools and then check for (node name = my node)? Is there perhaps already some code that does this that you could point me to?

 

 

Thanks for any assistance,

  • Daniel,

     

     

    Unfortunately, there is no way to find directly from a node address, which pools it belongs to. You are going to have to, as you guessed, loop through the pool members and look for a match on the address. Here's some code to get you started.
