String Array into a text file

By: Rajesh P.S.

An array is a fundamental data structure that enables the storage and organization of multiple variables of the same type in a single entity. By utilizing arrays, programmers can streamline and simplify their code in various scenarios. In VB.NET, arrays are derived from the Array class within the System namespace, which provides a rich set of methods and properties for manipulating array data.

Dim months(11) As String

One of the primary advantages of using arrays is the ability to reference related values using a common name and differentiate them by utilizing a numerical index or subscript. This allows for efficient access and manipulation of individual elements within the array.

VB.NET array

When creating an array in VB.NET, the default number of elements is set to zero. This means that initially, the array does not contain any specific elements, and it needs to be explicitly initialized with a specific size before storing data. Additionally, the reference to the array, known as the reference element, is set to null, indicating that it does not currently point to any valid memory location.

The elements of an array can be of any type, including an array type. The following VB.NET source code shows how to write the array content into a text file.
