Enclosing block?

[Guest learn]

Hi,

 

This is very strange (and simple, I believe) that following code got error:

Variable 'e' hides a variable in an enclosing block.

Can you explain what is an enclosing block and how to correct the code?

 

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Try

TestError()

Catch e As Exception

MessageBox.Show(e.message)

End Try

End Sub

 

Private Sub TestError()

Throw New Exception("11111111111")

End Sub

You've already got a variable called e, which is being passed to the subroutine. Just Catch ex As Exception instead or something.
