Exam 18: Files and Streams

Deserialize returns a reference of type:

In a class that's marked with the <Serializable()> attribute or that implements interface ISerializable,not every instance variable of the class needs to be serializable.

What is the exception thrown when an error occurs during serialization or deserialization?

You can use the FileAccess enumeration to control access to file when the file is opened.

Method ________ of class BinaryFormatter reads a serialized object from a stream and reforms the object in memory.

_______________ are used for long-term retention of large amounts of data.

Classes StreamIn and StreamOut are used to read from text files and output to text files.

Saving data to a file retains that data after the program terminates.

Console.In,Console.Out and Console.Error are used to take data in,to display data and to show error messages,respectively.

Which method creates a new file and returns a stream to process that file?

Every file automatically closes itself when it's no longer needed.

By default,array objects are not serializable.

What kind of exception is thrown if there's a problem opening or creating a StreamWriter?

No matter how complicated a program is or looks it can all be broken down into a series of 0's and 1's.

BinaryFormatter allows for only reading objects.

Records in a sequential access file are always sorted by a record key

Which of the following attributes is needed to indicate to the CLR that objects of the class can be serialized?

The standard output stream object enables a program to output data to the screen.

Data stored in a file is considered:

In a data hierarchy,data items become larger and more complex in structure as we progress from bits,to characters,to fields and up to large data structures.
