I have a log that outputs a line like this;
BATTERY VOLTAGE RESTORED
Note the blank(whitespace) after the word RESTORED, and then an odd Ascii character at the end.
I need to eliminate everything after the word restored and terminate the line at that point.
Thanks,

You could iterate through the characters in the string L-R and check the ASCII code of each character. As soon as you find a character whose ASCII code is outside of a certain range e.g. not a letter or number, return a string containing all the characters up to but not including that character.
Alternatively, if you know that only the last character isn't needed, use String.Substring to return a string that contains every character in a line minus the last character.

The problem with the L-R is that the ASCII is a random generated item. Not consistant for each entry.
I didn't think about the string.substring method. I will have to give that a look.
Thanks,

By L-R I mean process the string contents from left to right.
Check each character until you find one whose ASCII code that isn't valid for your purposes. Consult a table of ASCII codes to determine what the valid ranges might be.

Got it. I think I can mangle it from here!

It's rude to say this. Everyone's query is urgent. You have chosen to solicit help from a free site rather than pay for assistance so you should ask your questions politely and be prepared to wait for a response.

I don't know why you are thinking that I am not polite.
I know that everyone quries are urgent. Don't think that
writing like this
"Please help very urgent" is rude. I am requesting for help
bcos I am really in need and fed up with undefined value.
And I am so surprise to see this type of message.
Anyways SORRY if I said something wrong.

Then why did you write it? Why state the obvious?
The basic fact of the matter is that it is considered rude to write "Please help very urgent" when posting a message in an online forum where people offer their help for free. If you say this, it is more likely that your message will be ignored.

Don't be. If I hadn't have said it, someone else would.

Okay Thanks for letting me know that writing

Everyone who posts a question is in need and has (presumably) exhausted all other lines of enquiry. While I can appreciate your frustration, you should realize that it is inappropriate to use such phrases when posting questions. Courtesy and patience are more likely to yield results.

No problem.
On the subject of your question, presumably there is something wrong with your query criteria. Have you tried stepping through your code in debug mode to check that your query criteria has been constructed correctly?

I'm learning C# and have been given an assignment with a flexible requirement of reading / writing to a file.
I'm thinking of trying XML as a possible format for saving and retrieving data.
I've tried googling this but a couple of the sites I've gone too look complicated (perhaps it's complicated because I don't know how to relate XML with C# ?)
Can anyone suggest a basic tutorials / website that a newbie like myself can reference for the purpose of writing and reading an xml file?
Thanks in advance.

The obvious place to start is by reading the Framework documentation for the XML-related classes on MSDN. It's pretty dry stuff, but there will be small samples to get you going.
I would also recommend TopXML[^]. I've found this site useful in the past when I've wanted to learn how to do something with XML in .NET.

This site has many good articles and chapters from books that are very helpful....thats how I learned.
Just put XML in search box and go with it.
Good luck

Umm... reading and writing what? The .NET BCL provides good support for serialization.
