The customer needs to compress an array of bytes. So you are writing a method to compress bytes. The bytes are passed to the method in a parameter named document. The contents of the incoming parameter have to be compressed. Which code segment should you use?

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

You have just graduated from college, now you are serving the internship as the software developer in an international company. According to the requirements of the company CIO, you create a mobile Web Form which contains a mobile Calendar control named calDate.

So you have to modify the application. What should you do?

• A. You should define and implement an event handler for the XmlSerializer.UnknownNode event.
• B. You should apply an XmlInclude attribute to the PurchaseOrder class definition.
• C. You should apply an XmlIgnore attribute to the PurchaseOrder class definition.
• D. You should define a class that inherits from XmlSerializer and overrides the XmlSerialize.FromMappings 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();DeflateStream deflate = new DeflateStream(strm, CompressionMode.Compress);deflate.Write(document, 0, document.Length);deflate.Close();return strm.ToArray();
• 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();
