        string line;

        string motcletest = SEARCH.Text;

        using (System.IO.StreamReader file = new System.IO.StreamReader(@"D:\\TEST.txt"))
        {
            while ((line = file.ReadLine()) != null)
            {
                if ((line.Contains(motcletest)))
                {
                    richTextBox1.Text = line.ToString();
                    file.ReadLine();//read first line after matching line
                    file.ReadLine();//read second line after matching line
                    line = file.ReadLine(); //third line that you are looking for
                    foreach(var value in line.Split(','))//split by ,
                    {
                       //Add the value the controls(textbox)
                       //if the count is not fixed, you might need to create a control and add it to a panel
                    }
                }
            }
