Question

For example I have:

public static List<int> actorList = new List<int>();
public static List<string> ipList = new List<string>();

They both have various items in.

So I tried joining the values (string and int) together using a foreach loop:

  foreach (string ip in ipList)
    {
        foreach (int actor in actorList)
        {
            string temp = ip + " " + actor;
            finalList.Add(temp);
        }
    }

    foreach (string final in finalList)
    {
        Console.WriteLine(finalList);
    }

Although looking back at this, this was pretty stupid and obviously will not work, as the first forloop is nested.

My expected values for finalList list:

actorListItem1 ipListItem1
actorListItem2 ipListItem2
actorListItem3 ipListItem3

and so on..

So the values from the two lists are concatenated with each other – corresponding of their position in the lists order.

Use ZIP function of LINQ

List<string> finalList = actorList.Zip(ipList, (x,y) => x + " " + y).ToList();


finalList.ForEach(x=> Console.WriteLine(x)); // For Displaying

OR combine them in one line

actorList.Zip(ipList,(x,y)=>x+" "+y).ToList().ForEach(x=>Console.WriteLine(x));
