c# - How to convert a comma delimited string to array

Convert comma delimited String to Array

The String represents text as a sequence of UTF-16 code units. The String is a sequential collection of characters that is used to represent text. The String is a sequential collection of System.Char objects.

The following .net c# tutorial code demonstrates how we can convert a comma-delimited String object to an Array object. So, we will create a String Array from a String object whose substrings are separated by commas. Each comma-separated text of the String instance will create an item in the converted Array instance.

The String Split() method returns a String Array that contains the substrings in this instance that are delimited by elements of specified String or Unicode character array.

The String Split(Char, StringSplitOptions) method split a String into substrings based on a specified delimiting character and optionally String split options. So using this method we can Split a String by passing a comma delimiter to it and get a String Array object.
