How to use C# string Split

In C#, the Split method is a powerful tool for dividing a string into an array of substrings based on a specified delimiter. It allows developers to split a string into multiple parts based on a specific character or sequence of characters, facilitating efficient data extraction and manipulation.

Let's explore some examples to understand how the Split method works:

Splitting a String with a Single Character Delimiter

string data = "res,green,blue"; string[] fruits = data.Split(','); foreach (string fruit in fruits) { Console.WriteLine(fruit); }
Output: red green blue

In this example, we have a string variable named "data" containing a list of fruits separated by commas. By invoking the Split method with a comma (',') as the delimiter, the string is split into an array of substrings, where each fruit is an individual element in the resulting "fruits" array. We can then iterate over the array and process each fruit separately.

Splitting a String with Multiple Character Delimiters

string text = "Hello;World!How;Are;You"; string[] parts = text.Split(new[] { ';', '!' }); foreach (string part in parts) { Console.WriteLine(part); }
Output: Hello World How Are You

In this example, we split the string "text" using multiple delimiters, including semicolon (';') and exclamation mark ('!'). By providing an array of delimiters to the Split method, it separates the string into substrings based on any of the specified characters. The resulting array, "parts," contains each extracted substring.

Limiting the Number of Split Substrings

string sentence = "The quick brown fox jumps over the lazy dog"; string[] words = sentence.Split(new[] { ' ' }, 4); foreach (string word in words) { Console.WriteLine(word); }
Output: The quick brown fox jumps over the lazy dog

In this example, we split the string "sentence" into an array of substrings using a space (' ') as the delimiter. However, we specify a limit of 4 in the Split method. As a result, the splitting occurs only up to the fourth occurrence of the delimiter. The last substring contains the remaining portion of the original string.

Splitting on Multiple Lines

string poem = @"Roses are red, Violets are blue, Sugar is sweet, And so are you."; string[] lines = poem.Split(new[] { Environment.NewLine }, StringSplitOptions.RemoveEmptyEntries); foreach (string line in lines) { Console.WriteLine(line); }
Output: Roses are red, Violets are blue, Sugar is sweet, And so are you.

In this example, we split a multi-line string, "poem," using the Environment.NewLine constant as the delimiter. This constant represents the newline character sequence specific to the platform. The Split method separates the string into an array of lines, and we can process each line individually.


The Split method in C# is a versatile tool for dividing strings into substrings based on specified delimiters. It allows developers to extract relevant information, tokenize data, and perform various string manipulation operations efficiently. By utilizing the Split method, programmers can handle complex string parsing scenarios with ease and flexibility.
