Compilier will not recognize DataSet object.

[Dave]

Compilier will not recognize DataSet object.

As you can see below is from a test simple form with no
other code. I'm just trying to get any Aspx form to
recognize the DataSet object. You can see from the code
I am importing System.Data.Sql Client. I can get to
DataReader, DataView and DataTable but Visual Studio
won't even bring up DataSet on Intellisense, much less
compile it. The message I get is: "Reference required
to assembly 'System.Xml' containing the implemented
interface 'System.Xml.Ser ialization.IXml Serializable'.
Add one to your project.

But I don't want that one. I want the one in
System.Data.Sql Client. Same thing happens when I try
System.Data.ole DB. What painfully obvious step am I
missing here?

Thanks,

Dave

Hi,

DataSet is a class that enables you to store data on your application
memory and manipulate it. DataSet is made from DataTables and Relations
between them. to Fill DataTable one can use DataAdapter of SQLClient,
OLEDB, OracleClient or any other DB connectivity namespace.

As you see DataSet is not part of any DB namespace it is "global" class
that enable you to store data and you can decide what is the source of
that Table.

The DataSet can be handling as XML file. Actually it got XSD file
(schema) that set the Tables, fields, relations and other Meta data.
That is the reason way DataSet need reference to System.XML.

I have the VB.NET equivelent.

Imports System.Data
Imports System.Data.Sql Client
(rest of the code is at the bottom of the page.)

And that is what baffles me. I can get to the other
objects exposed from the namespace such as DataReader,
DataView and DataTable. It is _just_ DataSet that will
not get recognized.

do you have "using System.Data;" in your code and have a
reference to System.Data.dll ?

That is indeed odd. What error message do you get when you add the
reference?

System.Data.Sq lClient has nothing to do with DataSets. A

DataSet is not

provider-specific, so it resides in the System.Data

NameSpace. Adding a

reference to the Assembly does nothing but make it

available to your app.

Case in point, adding a reference to

System.Data.Sql Client, which as I

mentioned, is not necessary. So, why don't you just add

the reference that

the compiler told you to add?

I think I understand what you're trying to say. But
DataSet, according to all documention I've come across
(Microsoft, Wrox Books, etc.), says DataSet is part of
the System.Data namespace. I've also imported
System.Data.Sql Client. Both the compilier and
Intellisense pick up on other related objects such as
DataReader, DataView, DataTable and a host of others.
Why not DataSet?

The message I get is: "Reference required

I get this message with or without adding System.Xml.

Just an "Import" statement in the code behind the Aspx
form. (I'm using VB for my code.) I have not added a
reference to the assembly. Truth be told I didn't know I
had to add one to the assembly (or how to for that matter
but I can look it up). Would that explain the errant
behavior?

Definitely. That's what "Reference" in the error message refers to. Just go
to your Project window, find the "References " element, right-click and
select "Add Reference" from the context menu. Then select the Assembly from

Good Gravy I can't believe that worked. So I needed a
reference to System.XML in the assembly but I didn't need
to import it into the Aspx page. Still can't find any
documentation that mentions this but I'll at least know
what to do when the compilier complains again.

Thank you very much Kevin. Amazing how the rest of the
code is falling into place now.
