S3878 — Arrays should not be created for ParamArray parameters

Why is this an issue?

There’s no point in creating an array solely for the purpose of passing it to a ParamArray parameter. Simply pass the elements directly. They will be consolidated into an array automatically.

Noncompliant code example

Class SurroundingClass
    Public Sub Base()
        Method(New String() { "s1", "s2" }) ' Noncompliant: unnecessary
        Method(New String(12) {}) ' Compliant
    End Sub

    Public Sub Method(ParamArray args As String())
        ' Do something
    End Sub
End Class

Compliant solution

Class SurroundingClass
    Public Sub Base()
        Method("s1", "s2")
        Method(New String(12) {})
    End Sub

    Public Sub Method(ParamArray args As String())
        ' Do something
    End Sub
End Class
