.NET 3.5 version of code

[Matty J]

Hi

I'm having difficulty finding out what the latest version of the .NET
framework's C# code equivalent is for the following:

using System.Web.Script.Serialization;

JavaScriptSerializer ser = new JavaScriptSerializer();
result = ser.Deserialize<MyType>(JSON_encoded_string);


Any help would be appreciated.
Cheers
Matt

Thanks Juan.

I'm confused - is that not the same code as in my example?

When I compile my project using Visual Studio 2008 it tells me:
Warning
1 'System.Web.Script.Serialization.JavaScriptSerializer.JavaScriptSerializer()'
is obsolete: 'The recommended alternative is
System.Runtime.Serialization.DataContractJsonSerializer.' C:\inetpub
\Website\members\default.aspx.cs 53 32 WebProject

Any further ideas?
Cheers
Matt

re:
!> obsolete

Obsolete ?

Even ScottGu wonders why :

http://weblogs.asp.net/scottgu/arch...-a-tojson-extension-method-using-net-3-5.aspx

Read the sample code there, as well, as the user comments and Scott's replies.

Also, note that "obsolete' doesn't mean you can't use it, even if you get a warning.

The JavaScriptSerializer is currently marked obsolete - although I'm
not sure why (was going to ask someone about this today). It is very handy.

Note that obsolete doesn't mean removal in .NET 3.5
- it will be supported at least another version or two (or longer if I can convince them <g>)

Your code should work...with a warning.

Great, thanks Juan, that's what I needed to know.
