retrieve a specific line in text file

[kevin arana]

Hello.

Could anyone please show me an example of how to retrieve a specific line of
a text file (say line 3 of data.txt) into a string variable?

I have seen many examples on how to dump all the content into a string, and
how to read line-by-line consecutively, but how can i read just 1 specific
line?

Thank you.

Read the lines and skip the data read from the file until you reach line n.

Yes but this isnt exactly what i am looking for.

I saw an example posted in one of these newsgroups a long time a go and lost
the snippet. It worked really well.

If you could help me reproduce that example, i would apreciate it.

I feel sorry, but I don't think that 'StreamReader' provides a way to read a
certain line without reading the preceeding lines. There is nowhere stored
in the file where line n begins.

Kevin,

As Herfried wrote in a text file, you can only do as Herfried wrote.

In additon trying his message more clear you have only to read until that
the 3th line is read, than you can stop.

I hope this helps,

Cor

If the lines are all the same length, then you might be able to use the
Seek method of the stream to seek to the line you want and then read
that one line.
