XML Structure serialized in Disk for a dataset

[José Joye]

I have used the wizard of VisualStudio to generate a DataSet (typed
dataSet).
I need to have the structure serialized in XML in a nested way and not in a
table representation

e.g:
I have 3 tables: Companies- Departments- Employees
A company can have n Departments and a Department can have m employees

By default the DataSet is serialized this way:
<Companies>
....
</Companies>
<Companies>
....
</Companies>
<Companies>
....
</Companies>
<Departments>
....
</Departments>
<Departments>
....
</Departments>
<Employees>
....
</Employees>
<Employees>
....
</Employees>

I need it to be serialized this way (nested):
<Companies>
<Departments>
<Employees>
</Employees>
<Employees>
</Employees>
</Departments>
<Departments>
<Employees>
</Employees>
<Employees>
</Employees>
</Departments>
</Companies>
This will also imply that the "foreign keys" WILL NOT be stored in the XML
since they are not required in the target XML structure.

In the MSDN, I have seen that the DataRelation class provides a Nested
property that could be used. However, it does not remove the foreign keys.
Furthermore, modifying this property (on the relation) in the Graphic tool
provided by VS does not really work

Thaaaaaaaanks,
José
