How Can I Simplify String.Split Whitespace Handling in C#?

Streamlining String.Split for Whitespace in C#

The String.Split method, when used with whitespace as the delimiter, often requires defining a character array containing spaces and tabs. This can be repetitive and error-prone. Two simpler alternatives exist:

1. Using a null or Empty Separator:

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

Passing null or omitting the separator argument tells String.Split to use whitespace characters (as defined by Char.IsWhiteSpace) as delimiters.

2. Zero-Length Character Array:

<code class="language-csharp">string[] ssize = myStr.Split(new char[0]);</code>

Creating an empty character array achieves the same result: whitespace-based splitting.

Both methods are supported by the String.Split(char[]) documentation, which explicitly states that a null or empty separator array implies whitespace delimiters. This approach significantly simplifies code, reducing redundancy and the risk of errors associated with manually defining character arrays for whitespace.
