Solution 1

Try this one

C#

var inptuFileName = "C:\test.txt"";
var lines = File.ReadAllLines(inptuFileName).Where(arg = > string.IsNullOrWhiteSpace(arg));
int count  = lines.Count();

+5I'd suggest to use only single variable:
int CountOfEmptyLines = File.ReadAllLines("FullFileName").Where(arg = > string.IsNullOrWhiteSpace(arg)).Count();

There really isn't a nice way! :laugh:
This: Counting Lines in a String[^] shows a number of ways to count lines, and it wouldn't be difficult for you to modify any of those to count blank lines.

But there is no simple solution: "lines" don't really exist in text files, they are just a convention of the software which processes them and uses the "line separator character" to distinguish between them!

Mr OriginalGriff,i a m trying to Upvote your answer.still it's displaying a confirmed email message.but i didn't get any mail from codeproject.what i do for upvoting?

OriginalGriff 30-Mar-15 6:25am

Well if you got this message as an email, then you entered the email address correctly! :laugh:
If you didn't, then check your settings - top right of this page, hover over your user name, click "My Settings" and it'll show you the email address you used.
If you need to change it, do so and it should send you a confirmation (I think - I haven't changed email for years)

If you need another confirmation sent, then you probably need to ask here:
http://www.codeproject.com/suggestions.aspx
The admins read everything there and they can check the email system and resend if necessary. (But bear in mind they are probably in Canada, so there could be time differences between your post and their reading it)

I've just noticed that you signed up over a year ago - so presumably it's all been working since then?

Have you tried logging out and logging back in again, in case it's a cookie problem?
