How would I label these lines using coding?

I have already figured out how to identify and count up how many lines exist using this code:

using NXOpen;

using System;

public class FailedRegionCounting
{
    public static void Main()
    {

        Session theSession=Session.GetSession();
        Part workpart=theSession.Parts.Work;
 
        int numLine = 0;

        foreach (NXOpen.Curve tempFeat in workpart.Curves)

        {
            string name = tempFeat.Name;
            string a = "Line";           

            if (name.Contains(a))
            {
                numLine = numLine + 1;
            }    
        }
        Guide.InfoWriteLine("This analysis has " + numLine + " of Lines.");
    }
}

However, I would like to learn how I would label these lines on NX.

This is somewhat of a result I desire:
