Using VBA to assign range of cell values to array

问题:

I'm very new to VBA, to bear with me here.

I want to assign a set of variables the value of a set of ranges ie. run a brief code to simplify the following

Dim Sample 1 as string
Sample1 = activeworksheet.range("C17").value

Dim Sample 2 as string
Sample2 = activeworksheet.range("C18").value}

and so on

Following an excelfunctions.net tutorial, I know that I can shorten the declaration to

Dim Sample(1 to 20) as a string

But the tutorial drops it there(because it's a tutorial about names), suggesting I populate it as follows

sample(1)=activesheet.range("C7").value
sample(2)=activesheet.range("C7").value

and so on

I found the discussion below to be on the right track to answer my quest, but I am having trouble applying it to my situation. (Excel VBA Array Ranges for a loop)

As a follow up note, I am ultimately trying to assign values to these variables for use in the following procedures, rather than declaring and assigning them each time.

Thanks!

You should :

• Define the range you want to retrieve data

• For each cell of the range, retrieve your datas

  dim tab() As string, cell as range, i as integer
  i = 0
  redim tab(0)
  for each cell in ActiveWorksheet.Range("C1:C20")
      tab(i) = cell
      i = i + 1
      redim preserve tab(i)
  next
  

edit : I indent the code to display it correctly

Try something like this:

Sub test()
Dim sampleArr(1 To 20) As String
Dim i As Integer
Dim rng As Range, cel As Range

i = 1
Set rng = Range("C1:C20") 

For Each cel In rng
    sampleArr(i) = cel.Value
    i = i + 1
Next cel
For i = LBound(sampleArr) To UBound(sampleArr)
    Debug.Print sampleArr(i)
Next i

Also, if you know the range you want to put into an array, you can simply set an array to that range:

Sub test()
Dim sampleArr() As Variant
Dim i As Integer
Dim rng As Range, cel As Range

i = 1
Set rng = Range("C1:C20") ' Note, this creates a 2 Dimensional array

sampleArr = rng ' Right here, this sets the values in the range to this array.

For i = LBound(sampleArr) To UBound(sampleArr)
    Debug.Print sampleArr(i, 1) ' you need the ",1" since this is 2D.
Next i

End Sub

Additional way to the above you can only use:

Arr = ActiveWorksheet.Range("C1:C20").Value

Then you can directly use:

Arr(i,1) where i is C1 to C20 range!
