I need to make something that can get a specific line number and get the information in it into a String. And I couldn't figure out how I can do that.
Does anybody have a sample code/example that solves this problem?
Use File.ReadAllText (or Lines it might be) and then split the text by newline into an array of strings.
Then you can index into that array.

I've searched for this and cannot find any hint anywhere.
Basically there is a program that formats their file name like this
hello%20world%28hello%20world%29
which is supposed to mean hello world(hello world)
now im wondering is there any way that I could read every file name and anything that uses "%ascii" would be converted to normal text (e.g above).
Thanks in advance guys. I'm not that experienced in code and I'm hoping that someone could help me.
Use System.Uri.UnescapeDataString:
Uri.UnescapeDataString("hello%20world%28hello%20world%29");
Prints:
hello world(hello world)

How do you convert Html to plain text?
I want to show some Rss feeds in my application. But I do not want to show whole description.
I just want to show first couple of sentence of rss description.
Since lots of Rss feeds are coming as html, I want to convert to plain text and get sub string out of it.
Is there any way to html -> plain text in C#?
Thanks.
Please see filbys answer on How do you convert Html to plain text? for how to do this. You should also see Judah Himango's answer on the same question link. He basically says that you should use the HtmlAgilityPack which will do it for you.
Hope this helps!

Searching for a string in a pdf files
I'm working on an application that must find a location string in a PDF file. The string will look like "Location: XXXXXXXX" where XXXXXXXX is the value I need to use in my application.
How do I read this string from the PDF? Is there a library that I can use to read this? Once I get the string from the PDF I know how I'll process it. I just need to get the value out of the PDF.
Thanks!
You need something which can parse the PDF (you can't just search the file). What language do want to use?

.NET String.Format() to add commas in thousands place for a number
Hi Guys,
I have got 26750 in my string variable, something like below:
string str = "26750";
Now before showing on page, I want it to be converted into "26,750" format using c#. This value can increase as well as decrease also according to the result, so my format should work in both the cases.
Please suggest!
EDIT:
As I have written I have got string type value in my variable, I am trying with below code, but it is not working for me.
spnMiles.InnerHtml = String.Format("{0:n}", Miles);
It is not changing to the number format.
Please suggest!
