DataSet serialization - WebServices Posted: Jun 9, 2003 11:34 PM

Hallo,

I have a generated typed DataSet -> TestDataSet (inherited DataSet) and implemented Web Method: Save(DataSet d);
I need parameter of the DataSet type because of next extension (not TestDataSet type)

example.
TestDataSet d = new TestDataSet();
....// data filling
invoke at the client side web methods through proxy object: proxy.Save(d);

but at the server side I can't do casting:
.....
TestDataSet myData = (TestDataSet) d;
// exception - specified cast is not valid
I can just access to data "from base view".
But I need have type information about TestDataSet at server too.

Atribut XmlInclude(TestDataSet) does not function.
There is error during generated proxy class:

TestDataSet is derived from Xml.Serialization.IXmlSerializable and
therefore cannot be used with XmlInclude .....

Can anybody help me?

Thank for answer!
Tomas
