Question

In vb.net the methods have their parameters using ByVal by default, it’s better practice / common practice to make it explicit?

For example:

With ByVal:

Private Sub MySub(ByVal Q As String)
{
   ' ...
}
End Sub

Without ByVal:

Private Sub MySub(Q As String)
{
   ' ...
}
End Sub

Answer 1

According to Microsoft:

It is good programming practice to include either the ByVal or ByRef keyword with every declared parameter.

And if you use Visual Studio, it defaults to inserting ByVal if you don’t explicitly specify it.
