This means you are trying to reference an item in a collection that doesn’t exist. Say there are 5 items in the collection (index 0-4) and you try to reference item(5) - you’ll get this error.

Array value is start index is Zero(0).

ArrValue(ArrValue.Length-1) to get last value.

Hi,

The expression try to iterate 2 items from arr1.length. However arr2 and arr3 has only 1 item, then throw exception. Perhaps you should review your expression.

Hi,

I’m not sure what you want to do by this expression. However, for now, can you try to modify from arr1.length to arr2.length, as the following?

(From x In Enumerable.Range(0,arr2.length)
Let a = "LabelA: " & arr1(x)
Let b = "LabelB: " & arr2(x)
Let c = "LabelC: " & arr3(x)
Select res = String.Join(Environment.newLine, {a,b,c})).toarray
