Osservazioni

Instead of translating the XML for Analysis response from an XML format into an AdomdDataReader or CellSet, this method, returns an System.Xml.XmlReader that directly references the XML for Analysis response in its native XML format.

While the System.Xml.XmlReaderis in use, the associated AdomdConnection is busy serving the System.Xml.XmlReader. While in this state, the AdomdConnection can only be closed; no other operations can be performed on it. This remains the case until the Close method of the System.Xml.XmlReaderis called.

You should be prepared to catch any exception that can be thrown while using the System.Xml.XmlReader, such as the XmlException.
