Re: Treat a DataSet as a class structure

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

I appreciate yours and everyone elses responses. Each has helped me get a
little further.

I'm now able to create and populate my XML and XSD files correctly. I can
even see the XSD "class structure" within my program now. However, I can't
figure out how to treat my dataset that is read in
(myDataSet.ReadXml(filename)) as a class structure.

I've tried SomeTests.TestGroupsDataTable table = new
SomeTests.TestGroupsDataTable((DataTable)myDataSet.Tables["Group"]) but this
only gives me a null table.

How do I reference the dataset as if it were a class structure?

Hello Steve,

To generate a XML file from XSD file created in DataSet designer, we need
create a dataset object, fill in data and use its WriteXml() method to
generate the XML data.

Also you can read XML data directly into a dataset, for example, test.xml:

<SomeTests>
<TestsGroups>
<Group TestName="TestA" >
<Test>Run1</Test>
<Test>Run2</Test>
<Test>Run3</Test>
</Group>
</TestsGroups>
</SomeTests>


(Your original XML is not valid for a dataset, so I modify a little)

DataSet ds = new DataSet();
ds.ReadXml("c:\\test.xml");

foreach (DataTable dt in ds.Tables)
{

System.Diagnostics.Debug.WriteLine(dt.TableName);
}

We will get three tables in the dataset; TestsGroup, Group and Test.
Anyway, this is not a strong typed dataset. To create a strong type
dataset, you need to create the schema in the dataset designer.

Sincerely,

Luke Zhang
