Question:
You create a class library that is used by applications in three departments of your company. The library contains a Department class with the following definition.
public ref class Department {
public :
String= name;
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>Amy</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 ref class deptHandler : public IConfigurationSectionHandler { public :
Object= Create(Object= parent,
Object= configContext, System.Xml.XmlNode= section) {
Department= dept = gcnew Department();
dept->name = section->Attributes["name"].Value;
dept->manager = section->Attributes["manager"].Value; return dept;
}
};B public ref class deptElement : public ConfigurationElement { "A Composite Solution With Just One Click" - Certification Guaranteed 278 Microsoft 70-536 Exam
protected :
override void DeserializeElement(XmlReader= reader,
bool= serializeCollectionKey) {
Department= dept = gcnew Department();
dept->name = ConfigurationManager::AppSettings["name"]; dept->manager = ConfigurationManager::
AppSettings["manager"]; return dept;
}
};C public ref class deptHandler :
public IConfigurationSectionHandler {
public :
Object= Create(Object= parent,
Object= configContext, System.Xml.XmlNode section) {
Department= dept = gcnew Department();
dept->name = section->SelectSingleNode("name")->InnerText; dept->manager = section-
>SelectSingleNode("manager")->InnerText; return dept;
}
};D public ref class deptElement : public ConfigurationElement { protected :
override void DeserializeElement(XmlReader= reader,
bool= serializeCollectionKey) {
Department= dept = gcnew Department();
dept->name = reader->GetAttribute("name");
dept->manager = reader->GetAttribute("manager");
}
};
