How do I check to see if a string is within an array in Visual Basic?

Answer:

Dim things As String() = {"a", "b", "c"}
If things.Contains("a") Then
    ' do things
Else
    ' don't do things
End If

Use Contains:

If ShippingMethod.Contains(Shipping) Then
    'Go
End If

That implies case-sensitivity. If you want case insensitive:

If ShippingMethod.Contains(Shipping, StringComparer.CurrentCultureIgnoreCase) Then
    'Go
End If

I get the error 'Contains' is not a member of 'String()' if I try the above answer.

Instead I used IndexOf :

Dim index As Integer = Array.IndexOf(ShippingMethod, Shipping)
If index < 0 Then
    ' not found
End If
