Split String Value C#

Question

I have a string value which I need to get the middle bit out, e.g. "Cancel Payer" / "New Paperless".

These are an example of the string format:

"REF_SPHCPHJ0000057_Cancel Payer_20100105174151.pdf"
"REF_SPHCPHJ0000056_New Paperless_20100105174151.pdf"

Answer 1

Isn't this a place for regular expressions?

Regex re = new Regex(@".*_(?<middle>\w+ \w+)_.*?");
string name = "REF_SPHCPHJ0000057_Cancel Payer_20100105174151.pdf";
string middle = re.Match(name).Groups["middle"].Value;

Answer 2

string s = "REF_SPHCPHJ0000057_Cancel Payer_20100105174151.pdf";
string middleBit = s.Split('_')[2];
Console.WriteLine(middleBit);

Output is

Cancel Payer

Answer 3

I think that this regular expression:

Regex re = new Regex(@"\w+_\w+_(?<searched>.*)_\d*.pdf");

will meet your needs, if the pdf files always come to you as

REF_<text>_<your text here>_<some date + id maybe>.pdf

Answer 4

Cant write comments yet... but have to say that Jasons solution will not work correctly in case there is an underscore in the "middle bit". It will return only the part before underscore.
