Split string in C#

Here are some examples of how to split a string in C#:

Split a string by a newline:

string input = "This is a \nnew line";
string[] lines = input.Split('\n');

Split a string on both commas and newlines:

string input = "1,2\n3,4\n5,6";
string[] lines = input.Split(new char[] { ',', '\n' });

Split a string by another string:

string input = "The quick brown fox jumped over the lazy dog";
string[] words = input.Split(new string[] { "brown" }, StringSplitOptions.None);

Split a String by space:

string input = "This is a sentence.";
string[] words = input.Split(' ');

Split CamelCase or PascalCase string:

string input = "SplitCamelCaseString";
string[] words = Regex.Split(input, @"(?<!^)(?=[A-Z])");
// Output: ["Split", "Camel", "Case", "String"]

C# split string example:

string input = "Split this string";
string[] words = input.Split();
// Result: ["Split", "this", "string"]

String.Split method in C#: Using the Split method to split a string into an array of substrings.

string input = "Split using String.Split";
string[] parts = input.Split(new[] { ' ', '.' }, StringSplitOptions.RemoveEmptyEntries);
// Result: ["Split", "using", "String", "Split"]

Splitting a string by delimiter in C#:

string input = "Split by comma, separated values";
char delimiter = ',';
string[] values = input.Split(delimiter);
// Result: ["Split by comma", " separated values"]

C# split string into array:

string input = "Split string into array";
string[] array = input.ToCharArray().Select(c => c.ToString()).ToArray();
// Result: ["S", "p", "l", "i", "t", " ", "s", "t", "r", "i", "n", "g", " ", "i", "n", "t", "o", " ", "a", "r", "r", "a", "y"]

Splitting a string by multiple delimiters in C#:

string input = "Split by comma, semicolon; and space";
char[] delimiters = { ',', ';', ' ' };
string[] values = input.Split(delimiters, StringSplitOptions.RemoveEmptyEntries);
// Result: ["Split", "by", "comma", "semicolon", "and", "space"]

Tokenizing a string in C#: Tokenizing a string into words using StringTokenizer.

string input = "Tokenize this string";
StringTokenizer tokenizer = new StringTokenizer(input);
string[] tokens = tokenizer.ToArray();
// Result: ["Tokenize", "this", "string"]

C# split string by whitespace:

string input = "Split by whitespace";
string[] words = input.Split((char[])null, StringSplitOptions.RemoveEmptyEntries);
// Result: ["Split", "by", "whitespace"]

Using Regex to split a string in C#:

string input = "Split using Regex";
string[] parts = Regex.Split(input, @"\s+");
// Result: ["Split", "using", "Regex"]

Splitting a string into fixed-length segments in C#:

string input = "Split into segments";
int segmentLength = 4;
string[] segments = Enumerable.Range(0, input.Length / segmentLength)
    .Select(i => input.Substring(i * segmentLength, segmentLength))
    .ToArray();
// Result: ["Split", " into", " segm", "ents"]

C# split string into lines:

string input = "Split\nstring\ninto\nlines";
string[] lines = input.Split('\n');
// Result: ["Split", "string", "into", "lines"]
