How do I change string[] lines into output string?
C#
protected void Button1_Click(object sender, EventArgs e)
        {
            string data1 = TextBox1.Text;
            using (System.IO.FileStream fs = new System.IO.FileStream(Server.MapPath("~/data.txt"), System.IO.FileMode.Append, System.IO.FileAccess.Write, System.IO.FileShare.Read, 8, System.IO.FileOptions.None))
            {
                byte[] data = System.Text.Encoding.ASCII.GetBytes(data1);
                fs.Write(data, 0, data.Length);
                fs.Flush();
                fs.Close();
            }
        }

Why not use ReadAllText(String) instead?

How do you use ReadAllText as a string and not a string[]?

It just is.

The way he suggested, namely:
string stglines = File.ReadAllText(Server.MapPath("~/data.txt"));

5.

If you do not use the "[]" File.ReadAllText does not work. I need to convert string[] to string.
All you need to do is to loop through the collection of lines using StringBuilder class[^].

C#
StringBuilder sb = new StringBuilder();
foreach (string str in lines)
{
sb.Append(str);
}
//finally:
TexBox2.Text  = sb.ToString();


But, personally, i'd suggest to use solution 1.

[EDIT]
String.Concat() method[^] concatenates the elements of a specified String array.

Thank you, PIEBALDconsult. I forgot about that method!

Why not just String.Concat?

Good idea!
