VB.NET || How To Validate A Phone Number Using VB.NET

The following is a module with functions which demonstrates how to validate a phone number using VB.NET.

Not only does this function check formatting, but follows NANP numbering rules by ensuring that the first digit in the area code and the first digit in the second section are 2-9.


1. Validate Phone Number

The example below demonstrates the use of ‘Utils.IsValidPhoneNumber‘ to determine if a phone number is valid.

VB.NET || How To Shuffle & Randomize An Array/List/IEnumerable Using VB.NET

The following is a module with functions which demonstrates how to randomize and shuffle the contents of an Array/List/IEnumerable using VB.NET.

This function shuffles an IEnumerable and returns the results as a new List(Of T).

This function is generic, so it should work on IEnumerables of any datatype.


1. Shuffle – Integer Array

The example below demonstrates the use of ‘Utils.Shuffle‘ to randomize an integer array.


2. Shuffle – String List

The example below demonstrates the use of ‘Utils.Shuffle‘ to randomize a list of strings.


3. Shuffle – Custom Object List

The example below demonstrates the use of ‘Utils.Shuffle‘ to randomize a list of custom objects.

VB.NET || Word Wrap – How To Split A String Text Into lines With Maximum Length

The following is a module with functions which demonstrates how to split text into multiple lines using VB.NET.

The following function is an extension method, which takes a string, and splits it into multiple lines (array indices) of a specified length.

An optional boolean parameter specifies whether this function should break up long individual words to fit as many characters as possible on a line.

With this option enabled, if a word is too long to fit on a line, the word is broken up to fit as many characters as possible up to the maximum length on the current line, and the remaining characters gets moved to the next line (the next array index).

Note: Don’t forget to include the ‘Utils Namespace‘ before running the examples!


1. Word Wrap – Don’t Break Words

The example below demonstrates the use of ‘Utils.WordWrap‘ to split a string into multiple lines.

In this example, individual words are not broken up. They are simply moved onto the next line (if necessary).


2. Word Wrap – Break Words

The example below demonstrates the use of ‘Utils.WordWrap‘ to split a string into multiple lines.

In this example, individual words are broken up and moved onto the next line (if necessary), with the default hyphen character used, which is a dash (‘-‘).
