== Why is this an issue?

A ``++Do ... Loop++`` without a ``++While++`` or ``++Until++`` condition must be terminated by an unstructured ``++Exit Do++`` statement. It is safer and more readable to use structured loops instead.


=== Noncompliant code example

[source,vbnet]
----
Module Module1
    Sub Main()
        Dim i = 1

        Do                        ' Non-Compliant
            If i = 10 Then
                Exit Do
            End If

            Console.WriteLine(i)

            i = i + 1
        Loop
    End Sub
End Module

=== Compliant solution

[source,vbnet]
----
Module Module1
    Sub Main()
        For i = 1 To 9            ' Compliant
            Console.WriteLine(i)
        Next
    End Sub
End Module
