NO.1 You create an application by using the Microsoft .NET Framework 3.5 and Microsoft ADO.NET.
The application connects to a Microsoft SQL Server 2005 database. The application uses an XML
file that contains product data. A corresponding XSD file contains the schema of the XML file. You
need to ensure that the application performs the following tasks: Loads the XML file in a typed
DataSet Validates the XML file against the schema provided in the XSD file What should you do?
A.Use the xsd.exe tool along with the /loadxml parameter to create a typed DataSet object that
contains the data from the XML file.
B.Use the xsd.exe tool along with the /dataset parameter to generate a typed DataSet object.Use
the DataSet.ReadXml method to load the typed DataSet object.
C.Add the XSD file to the schema collections of the XmlReader object.Load the XML file in the
XmlReader object.Iterate through the XML nodes of the XMLReader object to create a new typed
DataRow for each node.
D.Load the XML file in an XmlDocument object.Call the XmlDocument.Validate method to validate
the XML file against the schema.Iterate through the XML nodes of the XmlDocument object to
create a new typed DataRow for each node.
