You create an application by using the Microsoft .NET Framework 3.5 and Microsoft ADO.NET.
You write the following code segment. (Line numbers are included for reference only.)
01 private List<string> GetEmployers() {
02 List<string> employers = new List<string>();
03 SqlCommand cmd = new SqlCommand();
04 …
05 XmlReader reader = cmd.ExecuteXmlReader();
06 while (reader.Read()) {
07
08 }
09 return employers;
10 }
The cmd object returns the following XML data structure.
<Resume>
<Name>
<Name.First>Shai</Name.First>
<Name.Last>Bassli</Name.Last>
</Name>
<Employment>
<Emp.OrgName>Wingtip Toys</Emp.OrgName>
…
</Employment>
…
</Resume>
You need to populate the employers list with each employer entry in the XML data structure.
Which code segment should you insert at line 07?
A.
if (reader.Name == "Emp.OrgName")
{
string employer = reader.ReadElementContentAsString();
employers.Add(employer);
}
B.
if (reader.Name == "Emp.OrgName")
{
reader.MoveToContent();
string employer = reader.Value;
employers.Add(employer);
}
C.
if (reader.Name == "Emp.OrgName" && reader.HasAttributes)
{
reader.MoveToFirstAttribute();
string employer = reader.Value;
employers.Add(employer);
}
D.
if (reader.Name == "Emp.OrgName")
{
reader.MoveToFirstAttribute();
if (reader.HasValue)
{
string employer = reader.Value;
employers.Add(employer);
}
}
