You want to split strings on different characters with single character or string delimiters.
using System;
class Program
{
static void Main()
{
string s = "split strings on different characters";
//
// Split string on spaces.
// ... This will separate all the words.
//
string[] words = s.Split(' ');
foreach (string word in words)
{
Console.WriteLine(word);
}
}
}
Output:-
split
strings
on
different
characters
The input string, which contains four words, is split on spaces and the foreach loop then displays each word. The result value from Split is a string[] array.
StringSplitOptions:-
While the Regex type methods can be used to Split strings effectively, the string type Split method is faster in many cases. The Regex Split method is static; the string Split method is instance-based. The next example shows how you can specify an array as the first parameter to string Split.
Program that splits on multiple characters [C#]
using System;
class Program
{
static void Main()
{
//
// This string is also separated by Windows line breaks.
//
string value = "Jeans\r\nBabyDress\r\nKidsPants\r\nManJacket";
//
// Use a new char[] array of two characters (\r and \n) to break
// lines from into separate strings. Use "RemoveEmptyEntries"
// to make sure no empty strings get put in the string[] array.
//
char[] delimiters = new char[] { '\r', '\n' };
string[] parts = value.Split(delimiters, StringSplitOptions.RemoveEmptyEntries);
for (int i = 0; i < parts.Length; i++)
{
Console.WriteLine(parts[i]);
}
//
// Same as the previous example, but uses a new string of 2 characters.
//
parts = value.Split(new string[] { "\r\n" }, StringSplitOptions.None);
for (int i = 0; i < parts.Length; i++)
{
Console.WriteLine(parts[i]);
}
}
}
Output:-
Jeans
BabyDress
KidsPants
ManJacket
Separate words::
Here we see how you can separate words with Split. Usually, the best way to separate words is to use a Regex that specifies non-word chars. This example separates words in a string based on non-word characters. It eliminates punctuation and whitespace from the return array.
Program that separates on non-word pattern [C#]
using System;
using System.Text.RegularExpressions;
class Program
{
static void Main()
{
string[] w = SplitWords("That is a cute girl, boy");
foreach (string s in w)
{
Console.WriteLine(s);
}
Console.ReadLine();
}
/// <summary>
/// Take all the words in the input string and separate them.
/// </summary>
static string[] SplitWords(string s)
{
//
// Split on all non-word characters.
// ... Returns an array of all the words.
//
return Regex.Split(s, @"\W+");
// @ special verbatim string syntax
// \W+ one or more non-word characters together
}
}
Output
That
is
a
cute
girl
boy
