I have a string value which I need to get the middle bit out of, e.g. "Cancel Payer" / "New Paperless".
These are examples of the string format:
"REF_SPHCPHJ0000057_Cancel Payer_20100105174151.pdf"
"REF_SPHCPHJ0000056_New Paperless_20100105174151.pdf"

Split is used to break a delimited string into substrings. You can use either a character array or a string array to specify zero or more delimiting characters or strings. If no delimiting characters are specified, the string is split at white-space characters.
public String[] split(String regex)This variant of the split method takes a regular expression as a parameter and breaks the given string around matches of this regular expression regex. Here, by default limit is 0. Returns: An array of strings is computed by splitting the given string.
The C function strtok() is a string tokenization function that takes two arguments: an initial string to be parsed and a const -qualified character delimiter. It returns a pointer to the first character of a token or to a null pointer if there is no token.
Definition and Usage. The split() method splits a string into an array of substrings. The split() method returns the new array. The split() method does not change the original string. If (" ") is used as separator, the string is split between words.
Use:
string s = "REF_SPHCPHJ0000057_Cancel Payer_20100105174151.pdf";
string middleBit = s.Split('_')[2];
Console.WriteLine(middleBit);
The output is
Cancel Payer
This is 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;
