Console application

What is console application?
A console application in the context of C # is an application that accepts input and displays output on a command line console with access to three basic data streams: standard input, standard output, and standard error.

A console application makes it easy to read and write characters from a console, either individually or as a line. It is the simplest form of a C # program and is usually called from the Windows command prompt. A console application usually exists in the form of a stand-alone executable file with minimal or no graphical user interface (GUI).

The program structure of a console application facilitates a sequential flow of execution between statements. The console application is designed for the keyboard and screen and is controlled by keyboard and system events generated by network connections and objects.

A console application is designed primarily for the following reasons:

Providing a simple user interface for applications that require little or no user interaction, such as: B. Examples of learning C# language functions and command line utilities.

Automated testing, which can reduce the automation implementation resources.

Console applications developed in C # have a main entry point (main static method) to execution that uses an optional array of parameters as the only argument to represent command line parameters.

The .NET Framework provides library classes to enable rapid development of console applications with output viewing capabilities in a variety of formats. System.Console (a sealed class) is one of the main classes used when developing console applications.

One limitation of the console application functionality is that strings returned by console functions using the original equipment manufacturer (OEM) code page may not be properly processed by functions using the American National Standards Institute (ANSI) code page. This problem can be resolved by calling the SetFileApisToOEM function to create OEM strings instead of ANSI strings.
