Overview:
                In this article i would like to publish an article related to "Console Class Methods in C#.Net".


Description:
                    Console is nothing but a black color screen.It is defined as a standard input,output error streams for a console applications.

It consists of different methods and events.

Method Name	Description
Beep()	Plays the sound of a beep through the console speaker.
Beep(int32,int32)	Plays the sound of a beep of a specified frequency and duration through the console speaker.
Clear()	Clears the console buffer and corresponding console window of display information.
OpenStandardInput()	Acquires the standard input stream.
OpenStandardInput(Int32)	Acquires the standard input stream, which is set to a specified buffer size.
Read(boolean)	Reads the next character from the standard input stream.
ReadKey()	Obtains the next character or function key pressed by the user. The pressed key is displayed in the console window.
ReadKey(boolean)	Obtains the next character or function key pressed by the user. The pressed key is optionally displayed in the console window.
ReadLine()	Reads the next line of characters from the standard input stream.
ResetColor()	Sets the foreground and background console colors to their defaults.
SetBufferSize()	Sets the height and width of the screen buffer area to the specified values.
Write(Many)	Writes the current terminator to the standard output stream.
WriteLine()	Writes the current line terminator to the standard output stream.

Note:
Write() and WriteLine() Methods are overloadable methods in different forms:
Write(Boolean),Write(Char),Write(Char[]),Write(Int32),Write(Int64),Write(Object),Write(Single),Write(String),Write(UInt32),Write(UInt64),Write(String, Object),Write(String, Object[]),Write(Char[], Int32, Int32),Write(String, Object, Object),Write(String, Object, Object, Object),Write(String, Object, Object, Object, Object),WriteLine(),WriteLine(Boolean),WriteLine(Char),WriteLine(Char[]),WriteLine(Decimal),WriteLine(Double),WriteLine(Int32),WriteLine(Int64),WriteLine(Object),WriteLine(Single),WriteLine(String),WriteLine(UInt32),WriteLine(UInt64),WriteLine(String, Object),WriteLine(String, Object[]),WriteLine(Char[], Int32, Int32),WriteLine(String, Object, Object),WriteLine(String, Object, Object, Object),WriteLine(String, Object, Object, Object, Object).
