Need help with .Equals method

jscott1226

I have written the following code. My problem is that I am trying to validate user input to check if it is a valid member of an array. Can I check the entire array at one time or do I have to check each element. The array is:

arrSKU = New String() {"AA123", "AA223", "AD543", "AD555", "BD666"}

My code is:

Dim k As Integer = 0
Dim bolFound As Boolean = False

Do While (k <= 4 And Not bolFound)
If txtSKU.Text.Equals(arrSKU) Then
bolFound = True
Else
k = k + 1
End If
Loop

If (bolFound) Then
MessageBox.Show("SKU is valid", "Title Bar Label", _
MessageBoxButtons.OK, MessageBoxIcon.Information)
Else
MessageBox.Show("Invalid SKU", "Title Bar Label", _
MessageBoxButtons.OK, MessageBoxIcon.Information)
End If

I have compiled my code with no errors but when I run it I always get the "Invalid SKU" message even if the entered SKU matches an element in the array.

Any help on this would be appreciated.

It would be easier to do this ...

[code]
Dim bolFound As Boolean = (arrSku.IndexOf(txtSKU.Text.Trim) <> -1)
...
[/code]
