Q92. - (Topic 2)
You are developing an application that includes the following code segment:
You need to implement the Open() method of each interface in a derived class named UseResources and call the Open() method of each interface.
Which two code segments should you use? (Each correct answer presents part of the solution. Choose two.)
A. Option A
B. Option B
C. Option C
D. Option D
Answer: A,C
Explanation:
* An interface contains only the signatures of methods, properties, events or indexers. A class or struct that implements the interface must implement the members of the interface that are specified in the interface definition.
* Example: interface ISampleInterface { void SampleMethod(); }
class ImplementationClass : ISampleInterface
{
// Explicit interface member implementation:
void ISampleInterface.SampleMethod()
{
// Method implementation.
}
static void Main()
{
// Declare an interface instance.
ISampleInterface obj = new ImplementationClass();
// Call the member.
obj.SampleMethod();
}
}
Q93. DRAG DROP - (Topic 1)
An application serializes and deserializes XML from streams. The XML streams are in the following format:
The application reads the XML streams by using a DataContractSerializer object that is declared by the following code segment:
var ser = new DataContractSerializer(typeof(Name));
You need to ensure that the application preserves the element ordering as provided in the XML stream.
How should you complete the relevant code? (To answer, drag the appropriate attributes to the correct locations in the answer area-Each attribute may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.)

Q95. - (Topic 2)
You need to write a console application that meets the following requirements:
. If the application is compiled in Debug mode, the console output must display Entering debug mode. . If the application is compiled in Release mode, the console output must display Entering release mode.
Which code should you use?
A. Option A
B. Option B
C. Option C
D. Option D
Answer: D
Explanation: #elif lets you create a compound conditional directive. The #elif expression will be evaluated if neither the preceding #if (C# Reference) nor any preceding, optional, #elif directive expressions evaluate to true. If a #elif expression evaluates to true, the compiler evaluates all the code between the #elif and the next conditional directive. For example: #define VC7 //... #if debug Console.Writeline("Debug build"); #elif VC7 Console.Writeline("Visual Studio 7"); #endif
Incorrect: Not B:
* System.Reflection.Assembly.GetExecutingAssembly Method Gets the assembly that contains the code that is currently executing.* Assembly.IsDefined Method Indicates whether or not a specified attribute has been applied to the assembly.
* System.Dignostics.Debugger Class Enables communication with a debugger.
Property: IsAttached
Gets a value that indicates whether a debugger is attached to the process.

A. var2 = ((List<int>) array1) [0];
B. var2 = array1[0].Equals(typeof(int));
C. var2 = Convert.ToInt32(array1[0]);
