Private Sub FindInMultiPKey(ByVal myTable As DataTable)
Dim foundRow As DataRow
' Create an array for the key values to find.
Dim findTheseVals(2) As Object
' Set the values of the keys to find.
findTheseVals(0) = "John"
findTheseVals(1) = "Smith"
findTheseVals(2) = "5 Main St."
foundRow = myTable.Rows.Find(findTheseVals)
' Display column 1 of the found row.
If Not (foundRow Is Nothing) Then
Console.WriteLine(foundRow(1).ToString())
End If
End Sub

I find the example in msdn. I wonder why the array findTheseVals declared
dimension as 2 instead of 3. There are 3 key elements but the size of the
array is only 2??
 
yes. i think so. But if declared as 3, there is error saying expecting 3
values but receiving 4... error something like that
