vb.net - adding vertical text each item in text file writeline with some text -

i populating listbox text & saving output textfile (sobj.txt)

'saving items of lb1 in file under c:\temp     dim integer     w = new io.streamwriter("c:\temp\sobj.txt")     = 0 lb1.items.count - 1         w.writeline(lb1.items.item(i))     next     w.close() 

this text file contains 3 (for example) entries, let's abc in 1st line, def in 2nd line & ghi in 3rd line.

now want append text file (mpadd.txt) using sobj.txt entries such following:

'appending listbox items file mpadd.txt      using sw new io.streamwriter("c:\temp\mpadd.txt", true)         sw.writeline("some text" & abc & "some text")         sw.writeline("some text" & def & "some text")         sw.writeline("some text" & ghi & "some text")     end using 

please in getting correctly. thanks.

just read lines first file (just 3 lines not problem) , loop on these lines adding prefix , postfix text like

edit following last example

dim commands() =  {     "cdhdef -t ftpv2 -c r -f {0} -x ",     "cdhdsdef -v cpusrg {0} ",     "cacls k:\aes\data\cdh\ftp\{0}\archive /e /g ossuser:c" }   dim counter integer = 0 dim objlines = file.readalllines("c:\temp\sobj.txt") using sw new io.streamwriter("c:\temp\mpadd.txt", true)     ' loop number of strings in commands (max 3 now)     x = 0 commands.length - 1         line = objelines(x).trim         ' check prevent empty lines used output          if line <> string.empty             sw.writeline(string.format(commands(counter), line))             counter += 1         end if     next end using 

this example use composite formatting define format string , progressive placeholder want insert value.

of course work if have 3 lines in input file
