For a class project I have to load a text file into a linked list. So far, I have been able to read from the file, but I am struggling to split it up into sections so that I can put it into the linked list.
For example, I would like to split these items up at the empty lines:
David
Hunter
No1
Admin
John
Smith
No11
Sales
Jane
Appleby
No5
Accounts
I have tried String[] people = record.Split('\n'); but of course, this just splits it at every line.
I have also tried:String[] people = record.Split('\n\r'); String[] people = record.Split('\r\n');String[] people = record.Split('\n\n');
but it won't compile due to "too many characters in character literal"
Could anyone please suggest a way to do this (preferably without regex)?

To split a string by newline, call the split() method passing it the following regular expression as parameter - /\r?\ n/ . The split method will split the string on each occurrence of a newline character and return an array containing the substrings. Copied!
Use the Split method when the substrings you want are separated by a known delimiting character (or characters). Regular expressions are useful when the string conforms to a fixed pattern. Use the IndexOf and Substring methods in conjunction when you don't want to extract all of the substrings in a string.
Split(String[], Int32, StringSplitOptions) Method This method is used to splits a string into a maximum number of substrings based on the strings in an array. You can specify whether the substrings include empty array elements. Syntax: public String[] Split(String[] separator, int count, StringSplitOptions options);
You can use String. Split() method with params char[] ; Returns a string array that contains the substrings in this instance that are delimited by elements of a specified Unicode character array.
You can get it accomplished by using
string[] people = record.Split(new string[] { "\r\n\r\n" },
StringSplitOptions.RemoveEmptyEntries);
or
string[] people = record.Split(new string[] { Environment.NewLine + Environment.NewLine },
StringSplitOptions.RemoveEmptyEntries);
What it does is it removes empty entries with StringSplitOptions.RemoveEmptyEntries and then splits where two linebreaks are right after each other.
