What is the function of the "With" keyword

Question

Given the code below, what does the "with" keyword do? I'm not very familiar with it, and I'm not sure of its purpose.

Sub NotePage_Load()


With Request.Form

Thanks Kevin

Answer 1

With is the equivalent of adding Request.Form before any references in the with block.

With Request.Form
    Dim count as int = .Count
End With

versus:

Dim count as int = Request.Form.Count

Answer 2

With allows you to omit the part after the with and just use the dot operator - . to access properties, members and methods.

Answer 3

Well it acts as an alias to Request.Form

So you don't need to do

Request.Form.this

or

Request.Form.this

you can just do

this

or

that

Answer 4

It's a shorthand... everything within the With..End With block will be treated as if something is appended in front of it.

Ex:

With Request.Form
  ["xxx"] = "yyy"
  ["aaa"] = "bbb"
End With

is equal to the following:

Request.Form["xxx"] = "yyy"
Request.Form["aaa"] = "bbb"
