[RESOLVED] Trying to read 2 text files and put into one

[WinnitBaker]

Hi guys, im trying to make a console application which reads 2 text files and outputs it into one text file. The outputted text file needs to remove any replicates of data from the 2 text files. Was wondering if people could tell me whats wrong with my code -

while (!sr.EndOfStream)
                    {
                        strList1.Add(sr.ReadLine());

                    }

                    while (!sr2.EndOfStream)
                    {
                        strList2.Add(sr2.ReadLine());
                    }

                    foreach (string st in strList2)
                    {

                        for (int i = 0; i < strList2.Count; i++)
                        {
                            if (sr.ReadLine() == st)
                            {
                                break;
                            }
                                sw.WriteLine(st);
  
                        }

                        foreach (string s in strList1)
                        {
                            sw.WriteLine(s);
                        }
