String redimming

[pmclinn]

I have a string(10) array.

I want to redim it so that I only have the last 9 strings in the array.
What is the best way to do this?


Example:
String(0) = Dog
String(1) = Cat
String(2) = Bird

I want the cat, and bird to remain and drop the dog from the array....

Something like this might help, although it's hardcoded:

Dim str(5)
str(0) = "Dog"
str(1) = "Bird"
str(2) = "Cat"
str(3) = "Horse"
str(4) = "Lion"

Dim x
For x = 0 To 3
str(x) = str(x + 1)
Next
str(4) = ""
ReDim Preserve str(4)

Using 'ReDim Preserve' you can only remove items from the end of the array.
However, you can use 'Array.Copy' to create a copy of the array and then
discard the original array.

pmclinn,
In addition to the other comments.

Rather then use an Array, consider using an ArrayList (.NET 1.0 & 1.1) or
List(Of T) (.NET 2.0).

Then you can use ArrayList.RemoveAt(0) or List(Of String).RemoveAt(0) to
remove the first element in the "array".

Something like:

' VB 2003 syntax
Dim list As New ArrayList
list.Add("Dog")
list.Add("Cat")
list.Add("Bird")
list.RemoveAt(0)

' VB 2005 syntax
Dim list As New List(Of String)
list.Add("Dog")
list.Add("Cat")
list.Add("Bird")
list.RemoveAt(0)

List(Of T) (.NET 2.0).

And since you are only using strings, try StringCollection (under the
System.Collections.Specialized namespace)

Mythran,
Yes!

StringCollection is a very good option in this case, as it covers .NET 1.0,
1.1 & 2.0!
