Manually dispose of class instance in VB.Net

Question

Yes, I realize Garbage Collector takes care of freeing up memory, and I also know of the inefficiencies in clearing up memory manually, however for educational purposes I would like to know how to dispose a class instance in VB.Net.

Answer 1

look at the example given in MSDN: http://msdn.microsoft.com/en-us/library/system.idisposable.aspx

to use it, you can either use Using block or call Dispose() directly. for example:

' use Using Block: 
Using r = New MyResource(100)
    Console.WriteLine(r.ToString())
End Using

' call Dispose directly:
Dim r = New MyResource(100)
Console.WriteLine(r.ToString())
r.Dispose()
