C# Syntax (Toggle Plain Text)
  StringBuilder sb = new StringBuilder();
                    string line;
                    string Temp = " ";
 
                    if (File.Exists(fileOpen.FileName)) 
                    {
 
                        StreamReader file = null;
                        try 
                        {
                            file = new StreamReader(fileOpen.FileName);
                            while ((line = file.ReadLine()) != null)
                            {
                                sb.AppendLine(line);
                            }
                           // textBox1.Text = sb.ToString();
 
 
 
                            foreach (string lines in File.ReadAllLines(fileOpen.FileName))
                            {
                                 string[] Split = lines.Split(new string[] { " ", "\n", "\r", "\t" }, StringSplitOptions.RemoveEmptyEntries);
 
                                foreach (string Splits in Split)
                                {
                                    Temp = Temp + "\n" + Split;
                                }
 
                                //show line by line after split
                                MessageBox.Show(Temp, "read by line");
                            }

Hi,

Its working fine.

private void MakeVerticalToHorizontal()
{
                  char delimiter = ' ';
                 string fileName = @"c:\sample.txt";
                 string ss = string.Empty;
                  StringBuilder sb;

                 StreamReader sr = new StreamReader(fileName);

   try
                {
   while (sr.Peek() >= 0)
   {
                                string r = sr.ReadLine();

MessageBox.Show(r);

   string[] items = r.Split(delimiter);

                               sb = new StringBuilder();

                              foreach (string ff in items)
{
   sb.Append(string.Concat(ff, "\r\n"));
    }

   ss = sb.ToString();

MessageBox.Show(ss);

                   }
          }
              finally
             {
              using (StreamWriter outfile =
                          new StreamWriter(@"c:\sample1.txt"))
               {
                                  outfile.Write(ss.ToString());
                          }

           sr.Close();
             }
}

Use this logic and make some changes if you need.

I posted a reply more than 12 hours ago but I do not see it. I will try again.
The following works. It might be a little difficult to understand but please try to understand it. The purpose of the second and third "for" loops is to write out data that does not have a matching number on the other line. The value of n should be the number of numbers that have a matching number on the other line.
string fileName = "sample.txt";
string[] first, second;
using (StreamReader sr = new StreamReader(fileName))
{
first = sr.ReadLine().Split();
second = sr.ReadLine().Split();
int n = first.Length < second.Length ? first.Length : second.Length;
for (int i = 0; i < n; ++i)
MessageBox.Show(string.Format("{0} {1}", first[i], second[i]));
for (int i = n; i < first.Length; ++i)
MessageBox.Show(string.Format(first[i]));
for (int i = n; i < second.Length; ++i)
MessageBox.Show(string.Format(second[i]));
}

Try this
private void button1_Click(object sender, EventArgs e)
{

loadText();
}

public void loadText()
{
using (StreamReader sr = new StreamReader(@"test.txt"))
{
string line;
while ((line = sr.ReadLine()) != null)
{
samList.Add(line);

}
}

transformText();
}

public void transformText()
{
foreach (string str in samList)
{
char[] strChar = str.ToCharArray();
addToListbox(strChar);
}

}

public void addToListbox(char[] ss)
{
int chLen = ss.Length;
int count = 0;
while (count < chLen)
{
if (count + 1 < chLen)
{
listBox1.Items.Add(ss[count] + " " + ss[count + 1]);
}
else
{
listBox1.Items.Add(ss[count]+ " " + "end line" );
}

count = count + 2;
}

}
