You create a class library that is used by applications in three departments of your Braindumps.
The library contains a Department class with the following definition.
public class Department {
public string name;
public string manager;
}
Each application uses a custom configuration section to store department-specific values in the
application configuration file as shown in the following code.
<Department>
<name>Hardware</name>
<manager>Braindumps</manager>
</Department>
You need to write a code segment that creates a Department object instance by using the field
values retrieved from the application configuration file. Which code segment should you use?
A. public class deptElement : ConfigurationElement {
protected override void DeserializeElement(
XmlReader reader, bool serializeCollectionKey) {
Department dept = new Department();
dept.name = ConfigurationManager.AppSettings[“name”];
dept.manager =
ConfigurationManager.AppSettings[“manager”];
return dept;
}
}
B. public class deptElement: ConfigurationElement {
protected override void DeserializeElement(
XmlReader reader, bool serializeCollectionKey) {
Department dept = new Department();
dept.name = reader.GetAttribute(“name”);
dept.manager = reader.GetAttribute(“manager”);
}
}
C. public class deptHandler : IConfigurationSectionHandler {
public object Create(object parent, object configContext,
System.Xml.XmlNode section) {
Department dept = new Department();
dept.name = section.SelectSingleNode(“name”).InnerText;
dept.manager =
section.SelectSingleNode(“manager”).InnerText;
return dept;
}
}
D. public class deptHandler : IConfigurationSectionHandler {
public object Create(object parent, object configContext,
System.Xml.XmlNode section) {
Department dept = new Deprtment();
dept.name = section.Attributes[“name”].Value;
dept.manager = section.Attributes[“manager”].Value;
return dept;
}
}
Answer: C
