How to go to new line in a text document using VB.Net

Using 

File.AppendAllText("c:\mytextfile.text", "This is the first line")
File.AppendAllText("c:\mytextfile.text", "This is the second line")

How do I make the second line of text appear under the first one, as if I hit the Enter key? Doing it this way simply puts the second line right next to the first line.

Using Environment.NewLine

File.AppendAllText("c:\mytextfile.text", "This is the first line")
File.AppendAllText("c:\mytextfile.text", Environment.NewLine + "This is the second line")

Or you can use the StreamWriter

Using writer As new StreamWriter("mytextfile.text", true)
    writer.WriteLine("This is the first line")
    writer.WriteLine("This is the second line")
End Using

if you have many of this calls It's way better to use a StringBuilder:

Dim sb as StringBuilder = New StringBuilder()
sb.AppendLine("This is the first line")
sb.AppendLine("This is the second line")
sb.AppendLine("This is the third line")
....
' Just one call to IO subsystem
File.AppendAllText("c:\mytextfile.text", sb.ToString())

If you have really many many strings to write then you could wrap everything in a method.

Private Sub AddTextLine(ByVal sb As StringBuilder, ByVal line as String)
    sb.AppendLine(line)
    If sb.Length > 100000 then
        File.AppendAllText("c:\mytextfile.text", sb.ToString()) 
        sb.Length = 0
    End If        
End Sub

Maybe:

File.AppendAllText("c:\mytextfile.text", "This is the first line")
File.AppendAllText("c:\mytextfile.text", vbCrLf & "This is the second line")

vbCrLf is a constant for a newline.
