List Exact Matches In 2 Columns On 2 Sheets

Most likely another very basic on...

2 worksheets.
Worksheet 1, holding all data in column C.
Worksheet 2, the value in column B.

In need for a function that list all exact matches of the values in worksheet 2 column B that are found in Column C of worksheet 1.

I got this VBA code that checks for the string in worksheet 2, column B, but it is a Instr, and I need a exact match and only the exact match. Is this difficult to modify and how?

Or would this be a regular array function?

(I would not need a macro, since the data change constantly and I prefer function as they update easily)


Function matchArray(ByVal testString As String, ByVal dataRange As Range, Optional IndexNum As Long) As Variant
Dim outRRay() As String
Dim rangeArray As Variant
Dim xColl As New Collection
Dim xVal As Variant
Dim rIndex As Long
