The Formatter class is used to provide base functionality for the common language runtime serialization formatters.

By default, a property or a field that returns an object or array of objects is automatically serialized.

The SerializableAttribute attribute specifies whether or not a class can be serialized. The Marshal-by-value objects are remotable objects that implement the ISerializable interface.

The Namespace property of the DataSet class is used to specify the namespace of a DataSet object.

The WriteXml method of the DataSet class is used to write XML schema and data from a DataSet object in XML format.

The Load method of the XmlDocument class is used to load the XML document in the memory stream.

The ImportNode method of the XmlDocument class is used to import the node from another XML document.

SoapFormatter is a simple, modular, extensible, and XML-based protocol. It is used to exchange messages between remoting applications.

RPC-Based Body Formatting is used to refer to the section 7 of the SOAP specification. In this formatting, all the parameters are contained within the single element in a SOAP message body.

The BinaryFormatter and SoapFormatter classes implement the IRemotingFormatter interface to support remote procedure calls (RPCs), and the IFormatter interface to support serialization of a graph of objects.

CDRom is used to specify that a drive is an optical disc device, such as a CD or DVD-ROM. Removable is used to specify that a drive is a removable storage device, such as a floppy drive or a USB flash drive.

The FileInfo class contains methods to create, delete, copy, and move files and properties related to a file.

Use the FileStream, MemoryStream, and StreamReader classes to perform the following operations:

• Read data from the byte stream
• Read data from the memory stream
• Read data from the file stream

The FileStream class is used to specify write, read, and other file-related operations either in synchronous or asynchronous manner.

The NegotiateStream class of the System.Net.Security namespace is used to provide a stream that uses the Negotiate security protocol for a client authentication and use the SslStream class of the System.Net.Security namespace to provide a stream that uses the Secure Socket Layer (SSL) security protocol to authenticate the server and optionally a client.

Use the Marshal class to allocate unmanaged memory, copy unmanaged memory blocks, and convert from managed to unmanaged types.

The StreamReader class is used to read characters from a byte stream. The StreamWriter class is used to write characters to a stream.

Use the Path class to get the file extension using the GetExtention() method and to change the file extension using the ChangeExtention() method.

Implement the Trace class to log any errors thrown by an application and direct the Trace output to a local log file.

The StreamReader class implements a TextReader that reads characters from a byte stream in a particular encoding. The System.IO.File.OpenText method creates a StreamReader that reads from an existing text file having the specified path.

When you inherit from the GZipStream class, you must override the three properties: CanSeek, CanWrite, and CanRead.

Use the following to perform the isolated storage tasks:

• The IsolatedStorageFile class
• The IsolatedStorageFileStream class
• The IsolatedStorageScope enumeration

The GZipStream class is used to provide methods and properties used to compress and decompress streams. It represents the GZip data format. This data format uses the same algorithm as the DeflateStream class, but can be extended to use other compression formats also.
