Split a String on newlines 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 split a String on newlines. In this .net c# tutorial code we will split a String object by new lines character ‘\n’ and ‘\r\n’ and create a String Array object. In a .net c# application, we can put a new line on a String object using some specified special characters. 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(String[], StringSplitOptions) method splits a String into substrings based on a specified delimiting String and optionally String split options.In this example .net c# code, we pass a String array ...

Split a String into an Array and join Array elements into a String 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 split a String instance into a String array and then how can we create a new instance of the String object by joining the String Array elements with a new separator. The String Split(Char, StringSplitOptions) method overload splits a String into substrings based on a specified delimiting character and optionally String split options. So, using this method we can split a String using a comma delimiter. The String Join() method concatenates the elements of a specified Array or the members of a collection, using the specified separator between each element or member. The String Join(String, String[]) met...

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 ...

Split a String into a List Split a String into a ListThe 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 split a String instance into a List object. So, in this .net c# tutorial code we will split a String instance into a String Array then we will convert the String Array into a List object. Here we will split a Strings using comma delimiter. The String Split() method returns a String Array that contains the substrings in this instance that are delimited by elements of a specified String or Unicode character Array. The String Split(Char, StringSplitOptions) method overload splits a String into substrings based on a specified delimiting character and optionally String split options. So, using this method we can split a String using...

Split a String and remove empty elements 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 split a String object and remove empty elements. So, in this .net c# tutorial code we will split a String instance using a comma delimiter and create a String Array object from the split String. While we create the String array from the String object we also remove the empty elements from the String Array. The String Split() method returns a String Array that contains the substrings in this instance that are delimited by elements of a specified String or Unicode character Array. The Split(Char[], StringSplitOptions) method splits a String into substrings based on specified delimiting characters and options. The StringSplitOptions is...

Split a String and trim elements 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 split a String object and trim elements. So, in this .net c# tutorial code we will split a String instance using a comma delimiter and create a String Array object from the split String. While we create the String array from the String object we also trim the elements of the String Array. Trim removes the whitespaces from each side of a string element. The String Split() method returns a String Array that contains the substrings in this instance that are delimited by elements of a specified String or Unicode character Array. Using the Select() method we can get the String split items instance. Then we can trim each item from the collection. ...

Convert StringBuilder characters to uppercase The StringBuilder class represents a mutable String of characters. The StringBuilder class cannot be inherited. The StringBuilder class represents a String-like object whose value is a mutable sequence of characters. Although StringBuilder and String both represent sequences of characters, they are implemented differently. The String is an immutable type. So, each operation that appears to modify a String object actually creates a new String. The following .net c# tutorial code demonstrates how we can convert StringBuilder instance characters to uppercase. So, in this .net c# tutorial code we will convert all of the characters of a StringBuilder object to uppercase characters. Such as if a StringBuilder content is ‘Red’ then we will convert it into uppercase characters as ‘RED’. There are no direct methods in the StringBuilder class to convert StringBuilder characters to uppercase characters...
