**`Split()`** in C# programming language is used to split a string into an array of characters or strings.

It returns an array of strings or characters, which we get by splitting the original string separated by the delimiter passed to the `Split()` method. In other words, where the delimiter is found, a substring is made an element of an array.

#   
## Syntax
```c#
string.Split(ch)
```

## Parameters
**`ch`**: This is the character or delimiter by which to split characters or strings in the original string.

## Return value
An array of strings or characters is returned.

## Code example
In the example below, we will create a string and form an array of from the delimiter specified.


// create your class
class StringSplitter
{
    // create main method
    static void Main()
    {
        // create strin
        string s1 = "Educative is the best";

        // split where there is whitespace
        string[] s2 = s1.Split(' ');  

        // print out elements of the array
        foreach (string elem in s2){
          // print element one by one
          System.Console.WriteLine(elem);
        }
    }
}

In the code above, the string `s1` was split to become an array of strings. The `Split()` method took white-space `' '` as  its parameter. So, anywhere the `s1` has white-space, that is where it should split. 

Finally, we looped through the returned array, and printed out its elements.

How to use the Split() method in C#

Split() in C# splits a string into an array based on a specified delimiter.
