How do I keep one line in a String and delete the rest?

[Daniel]

Hi

I would like to remove everything else but one line of text in a String.

I have tried using .Split("\n"), however I did not succeed.

The string contains three lines, but I only need the string to contain the
first line.

Can anybody help me?

Thanks

Daniel

Actually it's not "\n" it's "\r\n" if I'm not mistaken. In any case
Environment.NewLine.

string[] ts = t.Split(new string[] { Environment.NewLine },
StringSplitOptions.None); // written with VS2005

now you have an array of lines. you can do what you need to...

How do you know that Split didn't work...? Did you get any error messages?
What was the length of the array created by Split?

If your string is delimited by \n, then <stringVariable>.Split("\n")[0]
should give you the first line only...

some of your questions are answered here:

Normally, no exceptions, see the doc for return values in various
situations.
If it's delimited by '\n' characters you'll need to use \n with single
quotes around the \n: '\n'.
Yes, with the [0] at the end you'll get the first line, but you'll probably
get exceptions if you're not careful about the text that you're reading in.

Thank you for all the answers :-)

By using:

<stringVariable>.Split('\n')[0]

everything worked out perfectly!

Thanks
