Retrieving location of found text in array

I have a large file that is loaded into an array and by using the .Contains method I check to see if the array contains a certain sub string.

After called the .Contains method is their a way for me to get the index of the found object(s).

Example:

Dim foo() As String = {"1","2","3"}
If foo.Contains("2") Then
   'return the index of the found number in this case 1
Else
   Return False
End If

Have you tried, Array.IndexOf

e.g

var i = Array.IndexOf(yourArray, "2");

You want to look at Array.IndexOf

Dim foo() As String = {"1","2","3"}
Dim myIndex As Integer = Array.IndexOf(foo, "2")

It should return -1 if it is not in the array.

IndexOf will give you location of object in array. Use This:
