How to read specific text from file using starting line and ending line in C# .Net

protected void Page_Load(object sender, EventArgs e)
    {
        if (!this.IsPostBack)
        {

            using (StreamReader stRead = new StreamReader(Server.MapPath("File/TextFile.txt")))
            {
                int i = 0;
                string name = string.Empty;
                string valueFromtoEnd = string.Empty;

                while (!stRead.EndOfStream)
                {
                    if (i > 2 && i <= 4)
                    {
                        valueFromtoEnd += stRead.ReadLine();
                    }
                    else
                    {
                        name += stRead.ReadLine();
                    }
                    i++;
                    if (i > 4)
                    {
                        break;
                    }
                }
            }
        }
    }

It will read the line from 3 to 4
