syntax

[tailz]

Simple question, regarding .net syntax more than anything.
I'm a vb6 coder, new to .net and its way of working... anyway, I'm using the follow bit of code. If the Querystring item "ID" is not passed then szPage will be 'Nothing'.

Dim szPage as String = Request.QueryString("ID")
If szPage = "12345" Then
  'Do This
Else
  'Do Summat Else
End If

If ID is not passed this produces an error ... Now I can sort this by doing;

If Not (Request.QueryString("ID") Is Nothing) Then
  Dim szPage as String = Request.QueryString("ID")
  If szPage = "12345" Then
    'Do This
  Else
    'Do Summat Else
  End If
Else
  'Error
End If

I know .NET has some much better ways of working with objects and I am very tuned into vb6 which I find can be a prob when using .net. This code just seems a bit long winded for something thats going to be very common... is there a BETTER/shorter way of writing this code?

Cheers for any replys,

Well, you could create a function called 'ParseQueryString' that will do all the validation checks and have it return to you an empty string if the query string was not passed. You must remember that a string is a reference type, with its default value being null (not an empty string).

ye I realise that, I was more 'worried' about not writing code the 'correct' way.

I'll just create the function :P

thanks :]
