Definition
Clears the console buffer and corresponding console window of display information.
Exceptions
An I/O error occurred.
Examples
The following example uses the Clear method to clear the console before it executes a loop, prompts the user to select a foreground and background color and to enter a string to display. If the user chooses not to exit the program, the console's original foreground and background colors are restored and the Clear method is called again before re-executing the loop.
The example relies on a
GetKeyPress method to validate the user's selection of a foreground and background color.
![]()
This example demonstrates the CursorLeft and CursorTop properties, and the SetCursorPosition and Clear methods. The example positions the cursor, which determines where the next write will occur, to draw a 5 character by 5 character rectangle using a combination of '+', '|', and '-' strings. Note that the rectangle could be drawn with fewer steps using a combination of other strings.
Remarks
Using the Clear method is equivalent invoking the MS-DOS
cls command in the command prompt window. When the Clear method is called, the cursor automatically scrolls to the top-left corner of the window and the contents of the screen buffer are set to blanks using the current foreground background colors.
Note
Attempting to call the Clear method when a console application's output is redirected to a file throws a IOException. To prevent this, always wrap a call to the Clear method in a
try …catch block.

Function getch in C program prompts a user to press a character. It doesn't show up on the screen. Its declaration is in 'conio.h' header file. The function is not a part of standard C library.
C programming code for getch#include <stdio.h>#include <conio.h>
int main()
{ printf('Waiting for a character to be pressed from the keyboard to exit.n');
getch();
return0; }
When you run this program, it exits only when you press a character. Try pressing num lock, shift key, etc. (program will not exit if you press these keys) as these are not characters.
Try running the program by removing getch. In this case, it will exit without waiting for a character hit from the keyboard.
