      Description

      This rule applies whenever an If statement is followed by one or more ElseIf statements; the final ElseIf should be followed by an Else statement.

      The requirement for a final Else statement is defensive programming.
      The Else statement should either take appropriate action or contain a suitable comment as to why no action is taken. This is consistent with the requirement to have a final Case Else clause in a Select Case statement.

      Noncompliant Code Example

      If x = 0 Then
          DoSomething()
      ElseIf x = 1 Then
          DoSomethingElse()
      End If
      

      Compliant Solution

      If x = 0 Then
          DoSomething()
      ElseIf x = 1 Then
          DoSomethingElse()
      Else
          Throw New ArgumentException("...")
      End If
      

      Exceptions

      None
