How Can I Simplify String Splitting in C# Without Explicit Whitespace Specification?

Streamlining String.Split in C#: Avoiding Explicit Whitespace Definitions

String splitting based on whitespace is a common string manipulation task. The traditional method, using a character array to define whitespace characters, is cumbersome and prone to mistakes. This article presents a cleaner solution.

The String.Split method, when called without a separator parameter, automatically uses whitespace characters as delimiters. Therefore, this concise code:

<code class="language-csharp">string[] ssizes = myStr.Split();</code>

achieves the same result as explicitly defining whitespace characters. An alternative, equally efficient syntax is:

<code class="language-csharp">string[] ssizes = myStr.Split(null);</code>

Both methods leverage the Unicode standard's whitespace definition and the Char.IsWhiteSpace method internally.

This simplified approach improves code efficiency and reduces errors associated with manually defining character arrays. It also adheres to the standard String.Split behavior, promoting consistent and straightforward string manipulation.
