usage of Split in C#

Question

string[] data = lines[j].Split(new[] { ';' }, StringSplitOptions.RemoveEmptyEntries); Why the new is used above? please can someone explain this.

It's for new char[], which contains the ';' character. The below example demonstrates how to extract individual words from a block of text by treating white space and punctuation marks as delimiters. The character array passed to the separator parameter of the String.Split(Char[]) method consists of a space character and a tab character, together with some common punctuation symbols. public class SplitTest { public static void Main() { string words = "This is a list of words, with: a bit of punctuation" + "	and a tab character."; string [] split = words.Split(new Char [] {' ', ',', '.', ':', '	' }); foreach (string s in split) { if (s.Trim() != "") Console.WriteLine(s); } } } // The example displays the following output to the console: // This // is // a // list // of // words // with // a // bit // of // punctuation // and // a // tab // character

It's short for new char[]. The compiler infers that you mean to use a char array because it contains the ';' element. The following overload of the Split method is being called. http://msdn.microsoft.com/en-us/library/ms131448(v=vs.110).aspx
