Consider the code:
On Error Goto ErrorHandler
Using sr As StreamReader = New StreamReader(OpenFile)
str = sr.ReadToEnd
sr.Close()
End Using
Exit Sub
ErrorHandler:
If there is an error inside the Using
block how do you clean up the sr
object?
The sr
object is not in scope in ErrHandler
so sr.Close() cannot be called. Does the Using
block cleanup any resources automatically even if there is an error?
