iOS Question Append text in a file

[giagia]

How do I write on a text file and
add the line at the end file? If I Use File.WriteString, will be the file reset ?

If I Use File.WriteString, will be the file reset ?

Yes.
Two options:
1. Read the file with File.ReadString, add the new line and write it back.
2. Open an OutputStream with File.OpenOutput in append mode and write to this stream.

Can you write me a small example of code?

 

[Erel]

Dim s As String = File.ReadString(...)
s = s & CRLF & "new line"
File.WriteString(...)

 

[giagia]

Dim s As String = File.ReadString(...)
s = s & CRLF & "new line"
File.WriteString(...)

thank you !?
