vb.net Clear Array

Question

 

Can any one help, I am trying to clear an array info(8), set all components to zero, nothing.

Erase info causes failures with subsequent functions.

 

I have searched books and msdn forums without success.

The only reference I have found: [Call System.Array.Clear(info, info.GetLowerBound(0), info.Length)]

Unfortunately this don’t work .

Answer 1

What more do you want this:  

Array.Clear(Info, Info.GetLowerBound(0), Info.Length)

to do?

It sets all elements of the array to Nothing.  There isn't much more that can be done unless you want to fill the array with some initializer.

Answer 2

I have tried,
Array.Clear(Info, Info.GetLowerBound(0), Info.Length) which returns an error ' Index was outside the bounds of the array'

Answer 3

Why are you getting that error?  Put a breakpoint on that line to find out.  What are the bounds of the array?

Answer 4

 Sorry made a stupid error. The code works fine. Thanks for your patience.

Answer 5

Hi ALL,

An array can only have a lower bound of zero so why not simply use.>>

Dim info(0 To 20) As Integer

Array.Clear(info, 0, info.Length)

Answer 7

Hi,

I've declared a array inside the structure and i want to clear that array from other function. Here is my program,

Public class()
   
 Public Structure KBCContents
    Dim DEF_Array() As String 'Declare DEFinition Array
    Dim ValueTable As String 'Declare ValueTable
 End Structure

 Public Function process()
  Process step 1...
  Process step 2...
  Process step 3...
  Clear()
 End Function()

 Sub clear()
 
   Dim ClearStructureData As New KBCContents
  
   ClearStructureData.DEF_Array()="" ' This is not working; Need to know how to clear this array; also array size is not known. 
 
End Sub

End Class()

Let me know, how to clear "DEF_Array()" array contents

Thanks,

Baskar:

You should start a new thread and post your initialization code for the structure.
