You work as the developer in an IT company. Recently your company has a big customer.
The customer runs a large supermarket chain. You're appointed to provide technical support for the customer. The customer needs to compress an array of bytes. So you are writing a method. The array is passed to the method in a parameter named document. You need to compress the incoming array of bytes and return the result as an array of bytes.
Which code segment should you use?

• A.MemoryStream strm = new MemoryStream(document);DeflateStream deflate = new DeflateStream(strm, CompressionMode.Compress); byte[] result = new byte[document.Length];deflate.Write(result, 0, result.Length); return result;
• B.MemoryStream inStream = new MemoryStream(document);DeflateStream deflate = new DeflateStream(inStream, CompressionMode.Compress); MemoryStream outStream = new MemoryStream();int b;while ((b = deflate.ReadByte()) != -1) { outStream.WriteByte((byte)b);} return outStream.ToArray();
• C.MemoryStream strm = new MemoryStream(document);DeflateStream deflate = new DeflateStream(strm, CompressionMode.Compress);deflate.Write(document, 0, document.Length);deflate.Close();return strm.ToArray();
• D.MemoryStream strm = new MemoryStream();DeflateStream deflate = new DeflateStream(strm, CompressionMode.Compress);deflate.Write(document, 0, document.Length);deflate.Close();return strm.ToArray();

You work as the developer in an IT company. Recently your company has a big customer. The customer runs a large supermarket chain. You're appointed to provide technical support for the customer. Now according to the requirement of the customer, you create an application for its business partners to submit purchase orders. Its partners send XML documents to your customer. The application you create deserializes these XML documents into instances of an object named PurchaseOrder. You must make sure that if the deserialization process encounters any XML content that fails to map to public members of the PurchaseOrder object, the application collects details. So you have to modify the application. What should you do?

• A.You should define a class that inherits from XmlSerializer and overrides the XmlSerialize.FromMappings method.
• B.You should apply an XmlIgnore attribute to the PurchaseOrder class definition.
• C.You should define and implement an event handler for the XmlSerializer.UnknownNode event.
• D.You should apply an XmlInclude attribute to the PurchaseOrder class definition.

You work as the developer in an IT company. Recently your company has a big client. The client runs a large supermarket chain. According to the business requirement, the client needs a class which uses unmanaged resources. This class maintains references to managed resources on other objects. You must make sure that when the class instance is not needed, users of this class can explicitly release resources. What should you do? (choose more than one)

• A.Create a Dispose method that releases unmanaged resources and calls methods on other objects to release the managed resources.
• B.You should create a class destructor. The class destructor releases the unmanaged resources.
• C.You should make the class implement the IDisposable interface by defining it.
• D.You should create a class destructor. The class destructor releases the managed resources by calling methods on other objects.
• E.You should make the class inherit from the WeakReference class by defining it.
• F.You should create a Dispose method. The method forces garbage collection by calling System.GC.Collect.

You have just graduated from college, now you are serving the internship as the software developer in an international company. You develop an application where there's a method. You assign the output of the method to a string variable named fName. You are using the Microsoft Visual Studio 2005 IDE to examine the output of the method. You have to write a code segment. The code segment should print the following on a single line the message: "Test Failed: "
The value of fName if the value of fName does not equal "John"
Besides this, the code segment must facilitates uninterrupted execution of the application at the same time. You must make sure of this.
In the options below, which code segment should you use?

• A.If fName <> "John" Then Debug.Print("Test Failed: ") Debug.Print(fName)End If
• B.Debug.Assert(fName = "John", "Test Failed: ", fName)
• C.Debug.WriteLineIf(fName <> "John", _ fName, "Test Failed")
• D.If fName <> "John" Then Debug.WriteLine("Test Failed: ") Debug.WriteLine(fName)End If
