Getting the System.Type for String

[Nathan Sokalski]

I have the following code:

Dim values As New ArrayList()
values.Add("Yes ")
values.Add("No" )
values.Add("May be")
values.Add("Wha tever")
dim x as String()=values .ToArray()

However, I recieve an error saying an Object array cannot be implicitly
converted to a String array. I noticed, however, that there is an overload
of the ToArray() method that accepts a System.Type to convert the resulting
array to. However, I am having trouble getting the System.Type for String.
Can someone help me here? Thanks.

I think you need
GetType(String)

You will still need a type conversion as well, so you end up with

Dim x As String() = CType(values.To Array(GetType(S tring)), String())

I would have just used
Dim values As New List(Of String)
' ....
Dim x As String() = values.ToArray( )

Thanks, that worked great! I actually did use your suggestion of List(Of
String), I guess I just didn't think of that before since my boss gives me
such boring projects I'm a little out of practice with some of the classes I
used when I had all the free time I used to. Thanks again.

ArrayLists hold Objects (i.e. anything) but an array of Strings can only
contain Strings, hence your conversion error.

Are you still using VB'2003?
If /not/ have a play with Generics:

Dim values as New List(Of String)
values.Add("Yes ")
values.Add("No" )
values.Add("May be")
values.Add("Wha tever")
Dim x as String() = values.ToArray( )

HTH,
