we can create a read only property by using the keyword "Read only" before the syntax .
e.g

get
[statement]
end get
end property

Read-only is a variable.
It can't change by user.It can change itself
EX-

To Define a read only property in a class module you have to specify the "ReadOnly" Access Identifier in the Property Definition.

The example below will explain it better.

Public Class clsConnection

Public ReadOnly Property strConnString() As String
Get
strConnString = "Some Connection String here"
Return strConnString = ""

End Get
End Property
End Class Source: CoolInterview.com
