Declaring a array

[nishkarsh_k]

Hello every one, I am working on a Vb.net 2005 application. I came across two ways to declare a array, i just wanted to know is there any difference between them

Dim iTestArray() As Integer

and

Dim iTestArray As Integer()

Regards Nishkarsh

No, there isn't.

First of all, an Array isn't the same as an Integer. An Integer can't hold multiple values. To dim an array you should use the following:

Dim ArrayName As Array

Or:

Dim ArrayListName As New ArrayList

The difference between these two is (again, as far as I know :rolleyes: ) that the size of the ArrayList is dynamically increased when needed, and that the (regular) Array doens't do this. Cheers, Zaegra

Nishkarsh's original array declarations are absolutely correct. Your method of declaring it as 'Array' (System.Array) is generally the wrong thing to do. Declaring a variable of type 'Array' is a special purpose technique that is rarely required.

Then please explain to me how I can store multiple values in an Integer? Because as far as I know an integer is just a number? :wtf:

You can't store multiple values in an Integer. This is just the syntax you use when declaring arrays. i.e., Dim i() As Integer or Dim i As Integer() The parenthesis pair after either the identifier or the type indicates that it's an array of Integer, not a single Integer.

or

My advice is free, and you may get what you paid for.

I agree with David Anton. Example:

'Declare the array:
Dim myIntArray(2) as Integer

myIntArray(0) = 9

myIntArray(1) = 8

myIntArray(2) = myIntArray(0) - myIntArray(1) 'The value becomes 1 (9 - 8)

That's how it's used. -Ray
