How to add some code to c# Installer

I have made an installer which contains the exe and dlls, made in using Visual studio the thing is can i add some code to it?

example when it install i just want to run 3-4 lines of code.

1- Get mac address add to database, with a unique key.

And similarly on uninstall remove the mac address from the database .

Is this possible in this current scenario using the default setup project?

Solution

You will need to use a CustomAction for your installer. With this you can run a program, script, write a registry key, or whatever. Here's a simple example using a custom installer class to show a message during the installation (in VB.NET but easily translatable):

Public Overrides Sub Install(ByVal stateSaver As System.Collections.IDictionary)
  MyBase.Install(stateSaver)
  Dim myInput As String = Me.Context.Parameters.Item("Message")
  If myInput Is Nothing Then
    myInput = "There was no message specified"
  End If
  MsgBox(myInput)
End Sub

You would need to follow the steps in the link to fully reproduce the sample.
