C# - Split Methods

Split Function in C#

This is widely use in real time projects

Splitting strings in C# is a common operation, and it can be done using various methods depending on the requirements. Here are several ways to split strings in C# along with examples:

Basic Split Method

Using the string.Split method with a single character delimiter:

string input = "apple,banana,cherry";
string[] result = input.Split(',');

foreach (string s in result)
{
    Console.WriteLine(s);
}
// Output:
// apple
// banana
// cherry

Using the string.Split method with multiple character delimiters:

string input = "apple,banana;cherry orange";
char[] delimiters = new char[] { ',', ';', ' ' };
string[] result = input.Split(delimiters, StringSplitOptions.RemoveEmptyEntries);

foreach (string s in result)
{
    Console.WriteLine(s);
}
// Output:
// apple
// banana
// cherry
// orange

Advanced Split Scenarios

Splitting a string with a string delimiter:

string input = "one,two,,three,four";
string[] result = input.Split(new string[] { ",," }, StringSplitOptions.None);

foreach (string s in result)
{
    Console.WriteLine(s);
}
// Output:
// one,two
// three,four

Using Regex.Split to split by a pattern:

using System.Text.RegularExpressions;

string input = "apple123banana456cherry";
string pattern = @"\d+";
string[] result = Regex.Split(input, pattern);

foreach (string s in result)
{
    Console.WriteLine(s);
}
// Output:
// apple
// banana
// cherry

Using the string.Split method with options to remove empty entries:

string input = "apple,,banana,cherry";
string[] result = input.Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries);

foreach (string s in result)
{
    Console.WriteLine(s);
}
// Output:
// apple
// banana
// cherry
