The changes are related to the Request object and are shown in following table:

API Changes

Method Change
Request(item) In ASP, this property is a Collection. In ASP.NET, Request is a NameValueCollection property that returns a string based on the passed in item key.
Request.QueryString(item) In ASP, this property is a Collection. In ASP.NET, QueryString is a NameValueCollection property that returns a string based on the passed in item key.
Request.Form(item) In ASP, this property is a Collection. In ASP.NET, Form is a NameValueCollection property that returns a string based on the passed in item key.

The changes are basically the same for all properties involved.

If the item you are accessing contains exactly one value for the specified key, you do not need to modify your code. However, if there are multiple values for a given key, you need to use a different method to return the collection of values. Also, note that collections in Visual Basic .NET are zero-based, whereas the collections in VBScript are one-based.

For example, in ASP the individual query string values from a request to

http://localhost/myweb/valuetest.asp?values=10&values=20 would be accessed as follows:


<%
   'This will output "10"
   Response.Write Request.QueryString("values")(1)

   'This will output "20"
   Response.Write Request.QueryString("values")(2)
%>

Following code is generated by ASP2ASPX.
In ASP.NET, the QueryString property is a NameValueCollection object from which you would need to retrieve the Values collection before retrieving the actual item you want. Again, note the first item in the collection is retrieved by using an index of zero rather than one. 


<%
    'This will output "10"
    Response.Write(Request.QueryString.GetValues("values")(1 - 1))
    'This will output "20"
    Response.Write(Request.QueryString.GetValues("values")(2 - 1))
%>
