Hi,

C# is case sensitive

System.Drawing.Color localColor;

localColor = ((System.Drawing.Color)(ViewState["labelColor"]));

Lino
 
I am new to both C# and ASP.NET. I want to convert the VB.NET codes below to
C#:
Dim localColor As System.Drawing.Color
localColor = CType(ViewState("labelColor"), System.Drawing.Color)

I got an compilation error when I try the following code:
System.Drawing.Color localColor;
localColor = (System.Drawing.Color)(ViewState("labelColor");

Could someone tell me what is the equivalent codes in C#?
Also is there any site that shows all the C# syntaxes corresponding to those
of VB.NET?
 
you are missing a ) and to access the item from viewstate you need to use a
[] as it has an indexer.

but you dont need the (, so ...

System.Drawing.Color localColor;
localColor = (System.Drawing.Color)ViewState["labelColor"];

Will work.

ps

dident the compiler say you are missing )???
 
Thank both of you for your help. I missed one ) in my post but didn't miss
it in my original codes. I didn't understand the message that said that the
"Viewstate denotes a 'property' where a method was expected" until after
you pointed out the error with my using () instead of [].

Now my first question is solved but my second question still stands. Do you
know any site where I can look up C# syntaxes corresponding to those of
VB.NET?

Thank you.
 
System.Drawing.Color localColor =
(System.Drawing.Color)ViewState["labelColor"];

ViewState is an array, so use [], not () in C#. The cast was correctly done.
Why not do it all on one line, as above?

Great book for understanding language differences. Will not teach you how to
code .NET, but will help you go back and forth from VB.NET to C# with ease.

You should manage without a book, if you know vb.net you will manage with
c#, the first few bits of code will take awhile to get going but am sure you
will manage.

A quote from a well known Microsoft speaker at a conference (not word for
word :) ), 'when learning .NET, 10% of the effort goes into the language and
the other 90% the framework, chose the language your most familiar with then
move to different language' if you wish, this was amied at VBers getting
into C#.

Personally, I just jumped in with C# from VB6 background, but I have C++
under my belt so C# was quite easy.
