scope - integer

[Michael Fällgreen]

I like using the "Using Statement" when dealing with objects - you know its
disposed and thereby not in scope further down in the method. But how do you
"make scope" within a method for an int

This is not possible

' i is unknown
Using i as integer
......
end using
' i is unkopwn

you can do

' i is unknown
if true
dim i as integer
.....
end if
' i is unknown

but thats stupid.

How can you make "scope" in a method - it would be nice if this was possible

Scope
....
...
End Scope

Am I missing something?

Thanks

My understanding of the Using statement in VB.Net 2005 is that it
ensures that an object is disposed when you exit the block

Using sqc As New System.Data.SqlClient.SqlConnection(s)
' do something
End Using

is the same as

dim sqc as System.Data.SqlClient
try
sqc = New System.Data.SqlClient.SqlConnection(s)

' do something

finally

sqc.Dispose

end try


You cannot use 'Using' with something that does not implement
IDisposable.


Within C# you can have an 'anonymous' block

e.g.

{
int i = 19;
}

// i is not visible here


but I have not seen anything like that in VB.Net.
