Method

Arrays.FirstRowIndex

Warning

This item was deprecated in version 2020r2. Please use Arrays.FirstIndex as a replacement.

Description

Returns the index of the first row of the array.

Usage

result = array.FirstRowIndex

Part	Type	Description
result	Integer	The starting index of the array.
array	Array of any data type	The array whose first element number you want.

Notes

The FirstRowIndex function is used to determine the first element of an array. This is especially useful for writing code that loops through arrays so that you don't have to be aware of whether an array begins at 0 or 1 (they all begin at 0).

Arrays can have a maximum index value of 2,147,483,646.

Sample code

This code loops through an array and replaces each occurrence of X in an array with Y.

For i As Integer = names.FirstRowIndex To names.LastRowIndex
  If names(i) = "X" Then
    names(i) = "Y"
  End If
Next
