To C#

[RP]

Please help converting following VB code to C#. My attempted C# code
is given below:

[VB Code]
If Session("Cart") Is Nothing Then
Session.Add("Cart",New SortedList)
End If
Return CType(Session("Cart"),SortedList)
----------------------------------------------------------------
[Attempted C# Code]
If (Session("Cart") == "")
Session.Add("Cart",new SortedList)

return SortedList Session("Cart");

1. C# is case sensitive. If must be if.
2. Session("Cart") in your VB-Examble is not a fuction call, but an access
to a default property, wich is an indexer in C#. You have to call it with []
instead of () (like array element access).

(I assume Session here is the Session-object of ASP.NET. If it is a method
here, then calling with () is right.)

Session.Add("Cart",new SortedList)

3. Constructors (as well as methods) have allways to be called with
parantheses, even if the parameterlist ist empty.

>
return SortedList Session("Cart");

4. To Cast to another type, set the typename in parantheses before the
expression.

[Good C# Code]
if (Session["Cart"] == null)
Session.Add("Cart", new SortedList);

return (SortedList)Session("Cart");

Christof,

Your code needed some correction. I modified like this and it worked:
=======================================
if (Session["Cart"]==null)
{
Session.Add("Cart",new SortedList());
}
return (SortedList) Session["Cart"];
=======================================
Thanks for your help.

My take:

{
SortedList list = (SortedList)Session["Cart"];
if (list == null)
{
list = new SortedList();
Session["Cart"] = list;
}
return list;
}
