How to Split a String by Another String in C#?

Split a string using another string in C#

The

Split() method in C# is typically used to split a string based on a single character. However, in some cases you may need to split a string using another string as a delimiter. This article demonstrates how to achieve this using the string array overload of the Split() method.

Question:

Given a string containing multiple delimiters, you need to split the string into an array of substrings, each substring separated by a delimiter.

Example:

Split the string "THExxQUICKxxBROWNxxFOX" using the delimiter "xx" to get the following array:

• THE
• QUICK
• BROWN
• FOX

Solution:

To split a string using another string, you can use the string array overload of the Split() method. This overload takes an array of strings as a delimiter argument, allowing you to specify multiple delimiters if necessary.

The following code demonstrates how to split a string using the delimiter "xx":

<code class="language-csharp">string data = "THExxQUICKxxBROWNxxFOX";

string[] splitData = data.Split(new string[] { "xx" }, StringSplitOptions.None);</code>

The

StringSplitOptions.None parameter specifies that no special splitting options should be applied.

Result:

The

splitData array will contain the following substrings:

• THE
• QUICK
• BROWN
• FOX
