Inheritance help

[igorsky]

I’m trying to inherit System.IO.StreamReader in to my class
But I’m getting an error “ Class ‘MyClass’ must declare a ‘Sub New’ because its base its class ‘StreamReader’ does not have an accessible ‘Sub New ‘ that can be called with no arguments.

Imports System.IO

Public Class Info
    Inherits StreamReader
    

End Class

Please help.

What are you making that you need to inherit from StreamReader?

Anyway since StreamReader has no default constructor then you have to have constructor for your derived class that creates the base class, passing in the parameters for its constructor. In other words since you can't do:

Dim sr As New IO.StreamReader()

then you have to have a constructor in your object that handles passing in whatever. Add something like this to your class:

Public Sub New()
    MyBase.New(AddParametersToCreateTheBaseObjectHere)
End Sub
