Question

I have a small struct and I have to compare the values to find which ones have the same FreeFlow text, and then grab that struct ENumber.

   public struct Holder
    {
        public string FreeFlow;
        public int ENumber;
    }

and here is how I add them

foreach(Class1.TextElement re in Class1._TextElements)
            {
                //create struct with all details will be good for later
                Holder ph = new Holder();
                ph.FreeFlow = re.FreeFlow;
                ph.ENumber = re.ENumber;
                lstHolder.Add(ph);
            }

      foreach(Class1.TextElement2 re in Class1._TextElements2)
            {
                //create struct with all details will be good for later
                Holder phi = new Holder();
                phi.FreeFlow = re.FreeFlow;
                phi.ENumber = re.ENumber;
                lstHolder2.Add(phi);
            }

I can do a comparing using a foreach within a foreach, but I think this will not be the most effective way. Any help?

EDIT: I am trying to determine if freeflow text is exactly the same as the other struct freeflow text

Answer 1

I have to compare the values to find
which ones have the same FreeFlow
text, and then grab that struct
ENumber.

If you can use LINQ you can join on the items with the same FreeFlow text then select the ENumber values of both items:

var query = from x in Class1._TextElements
            join y in Class1._TextElements2 on x.FreeFlow equals y.FreeFlow
            select new { xId = x.ENumber, yId = y.ENumber };

foreach (var item in query)
{
    Console.WriteLine("{0} : {1}", item.xId, item.yId);
}

EDIT: my understanding is the FreeFlow text is the common member and that ENumber is probably different, otherwise it would make sense to determine equivalence based on that. If that is the case the join query above should be what you need.
