Reading each line in a variable

[ltt19]

Hi,
I want to read line by line in a variable, but it could not be foward only , it need to be forward and backward, it also needs to say me which line it is reading. I do not know if it is possible.

Thanks in advance

Variables in and of themselves don't have "lines." Please elaborate.

Explaining better,

I need to read echa line in a variable, that is big, and has many lines, i need something like:
ThisLine = FullVaraible.ReadNextLine
or
ThisLine = FullVariable.ReabBackLine
or even
ThisLine = FullVariable.Readline(87)

this would be perfect

Did I explain it better? Anything just reply this post.

See if String.Split can help you out.

Not sure if I understand what you want to do...

\\\
Dim astr() As String = Split(s, ControlChars.NewLine)
///

.... will split a string containing multiple lines separated by newline
strings and assign the parts to an array of strings.

If you have a very large string and want to read through it, check out the
StringReader class. It allows you to read through a string with methods
like .Read and .ReadLine and .Peek:

Dim sRdr As New StringReader(sSomeLongString)
Dim sLine As String

sLine = sRdr.ReadLine()

It does not seem to allow backward navigation, however.

You can also use a MemoryStream with a array of characters:

Imports System.Text

Dim oMStrm As New MemoryStream(Encoding.Default.GetBytes(sSomeLargeS tring))

The MemoryStream allows seeking.

Hope this helps
