Like [Slaks pointed out](https://stackoverflow.com/a/6727960/1366033), you can use `Contains` on an `enumerable` collection.  But I think readability suffers.  I don't care if some list ***contains*** my variable; I want to know if my variable is ***in*** some list.  


You can wrap contains in an extension method like so:

```vb
Imports System.Runtime.CompilerServices
Module ExtensionMethods

    <Extension()> _
    Public Function [In](Of T)(ByVal item As T, ByVal ParamArray range() As T) As Boolean
        Return range.Cast(Of T).Contains(item)
    End Function

End Module
```

Then call like this:

```vb
If ToStatus.In("1CE","2TL","2PM") Then
```

I just want to know if there's an approach in VB.NET that can find if a specific value exist on a list or something which can use in my If-else condition. What I'm doing now is to use this:

    If ToStatus = "1CE" Or ToStatus = "2TL" Or ToStatus = "2PM" Then
        'Do something
    Else
        'Do something
    End If

This works fine, but how if I have hundreds of string to compare to `ToStatus` in the future? It will be a nightmare! Now, if such functionality exists, how can I add "And" and "Or" in the statement? 

Thanks in advance!
