QUESTION 82
You write the following code to implement the CompanyClass.MyMethod function.
public class CompanyClass
{
public int MyMethod(int arg)
{
return arg;
}
}
You need to call the CompanyClass.MyMethod function dynamically from an unrelated class in your assembly.
Which code segment should you use?
A.CompanyClass myClass = new CompanyClass(); Type t = typeof(CompanyClass); MethodInfo m = t.GetMethod("MyMethod"); int i = (int)m.Invoke(this, new object[] { 1 });
B.CompanyClass myClass = new CompanyClass(); Type t = typeof(CompanyClass); MethodInfo m = t.GetMethod("MyMethod"); int i = (int) m.Invoke(myClass, new object[] { 1 });
C.CompanyClass myClass = new CompanyClass(); Type t = typeof(CompanyClass); MethodInfo m = t.GetMethod("CompanyClass.MyMethod"); int i = (int)m.Invoke(myClass, new object[] { 1 });

QUESTION 83
You create a class library that contains the class hierarchy defined in the following code segment. (Line numbers are included for reference only.)
01.
public ref class Employee {

02.

03.
public :

04.
String= Name;

05.
};

06.

07.
public ref class Manager : public Employee {

08.

09.
public :

10.
int Level;

11.
};

12.

13.
public ref class Group {

14.

15.
public :

16.
array= Employees;

17.
};


You create an instance of the Group class. You populate the fields of the instance. When you attempt to serialize the instance by using the Serialize method of the XmlSerializer class, you receive

InvalidOperationException. You also receive the following error message: "There was an error generating the
XML document."
You need to modify the code segment so that you can successfully serialize instances of the Group class by using the XmlSerializer class. You also need to ensure that the XML output contains an element for all public fields in the class hierarchy.
What should you do?
A.Insert the following code between lines 14 and 15 of the code segment: [XmlArray(ElementName="Employees")]
B.Insert the following code between lines 3 and 4 of the code segment: [XmlElement(Type = __typeof(Employee))] and Insert the following code segment between lines 8 and 9 of the code segment: [XmlElement(Type = __typeof(Manager))]
C.Insert the following code between lines 14 and 15 of the code segment: [XmlArrayItem(Type = __typeof(Employee))] [XmlArrayItem(Type = __typeof(Manager))]
D.Insert the following code between lines 14 and 15 of the code segment: [XmlElement(Type = __typeof(Employees))]

QUESTION 117
You work as an application developer. You are currently in the process of creating a new application.
You are required to read compressed data files that have been sent by company's sales offices. These data files are less than 4 GB in size, but were compressed without cyclic redundancy.
You want to write a method that receives the compressed files and return the uncompressed data as a byte array.
What should you do?
A.Use the following code: public byte [] DecompressFile (string file)

{
FileStream fs = new FileStream (file, FileMode, Open); DeflateStream cs = new DeflateStream (fs,
CompressionModc. Decompress, true) byte [ ] data = new byte [fs.Length -l];
cs. Read (data, (), data, Length);
cs. Close ();
return data;
}
:
B.Use the following code;
public byte [] DecompressFile (string file)
{
FileStream fs = new FileStream (file, FileModc, Open); GZipStream cs = new GZipStream {fs, Compress
iotiMndo. Decompress) byte [ ] data = new byte [fs. Length -1]; cs. Read (data, 0, data.Length);
return data:
}
C.Use the following code:
public byte [] DecompressFile (string file)
FileStream fs = new FileStream (file, FileMode,Open); DeflateStream cs = new DeflateStream (fs,
CompressionMode. Decompress) byte [ ] data = new byte [fs.Length -l];
cs. Read (data, 0, data.Length);

QUESTION 118
You write the following class that has three methods.
public class SimpleEmployee {
public string GetEmployeeId() { return employeeId; } public string GetName() { return employeeName; }

public string GetTitle() { return jobTitleName; }
You need to expose the class to COM in a type library. The COM interface must not expose the method GetEmployeeId. The GetEmployeeId method must still be available to managed code. You need to hide the GetEmployeeID method from the COM interface.
What should you do?
A.Apply the ComVisible attribute to the class and methods in the following manner.
[ComVisible(false)]
public class SimpleEmployee {
public string GetEmployeeId() { return employeeId; } [ComVisible(true)]
public string GetName() { return employeeName; }
[ComVisible(true)]
public string GetTitle() { return jobTitleName; }
B.Apply the ComVisible attribute to the class and methods in the following manner.
[ComVisible(true)]
public class SimpleEmployee {
public string GetEmployeeId() { return employeeId; } [ComVisible(true)]
public string GetName() { return employeeName; }
[ComVisible(true)]
public string GetTitle() { return jobTitleName; }
C.Apply the ComVisible attribute to the GetEmployeeId method in the following manner.
public class SimpleEmployee {
[ComVisible(false)]
public string GetEmployeeId() { return employeeId; } public string GetName() { return employeeName; }
public string GetTitle() { return jobTitleName; }
D.Change the access modifier for the GetEmployeeId method in the following manner.
public class SimpleEmployee {
protected string GetEmployeeId() { return employeeId; } public string GetName() { return employeeName; }
public string GetTitle() { return jobTitleName; }
