Another beginner question

[endo]

Help! I'm new to C# and keep getting stuck on things which should be pretty simple

Can anyone tell me why this loop repeats the output found in the menu( ) 3 times when a number is entered?

class Tester
	{
		private const int MAX_BOOKS = 5;
		static private Book[] library = new Book[ MAX_BOOKS ];
/*
		Book[] Library
		{
			get
			{
				return library;
			}
		}
*/
		/// <summary>
		/// The main entry point for the application.
		/// </summary>
		/// 
		


		static int menu( )
		{
			Console.WriteLine( "There are {0} books in the library", library.Length );
			Console.WriteLine( "Please enter and option:" );
			Console.WriteLine( "1. Enter book details" );
			Console.WriteLine( "2. Display book details" );
			Console.WriteLine( "5. Exit" );
			return Console.Read( );
		}

		[STAThread]
		static void Main( )
		{
			int choice;

			do
			{
				choice = menu( );

				switch( choice )
				{
					case '1':
						for( int i = 0; i < library.Length; i++ )
						{
							
						}		
						break;

					case '5':
						Console.WriteLine( "Exiting...." );
						break;
					
					default:
						Console.WriteLine( "Invalid choice. Please try again." );
						break;
				}
			}while( choice != '5' );
		}
	}

Also, while on the subject of console programs what is the best way to clear the console?

Console.Read() is reading newlines.

Try Console.ReadKey() instead.

	class Test
	{
		static ConsoleKeyInfo menu()
		{
			Console.WriteLine("Please enter and option:");
			return Console.ReadKey();
		}

		[STAThread]
		static void Main()
		{
			bool quit = false;
			do
			{
				switch (menu().KeyChar)
				{
					case '1':
						Console.WriteLine("You pressed 1");
						break;

					case '5':
						Console.WriteLine("You pressed 5");
						quit = true;
						break;

					default:
						Console.WriteLine("You pressed something else");
						break;
				}
			} while (!quit);
		}
	}

Also, to clear the console use Console.Clear()

Also, to clear the console use Console.Clear()

Thanks for that, I'll try i tlater when I get a chance. Must've been blind not to Clear( ) in the class description!

why does my compiler not recognise Console.Clear or Console.ReadKey??

You're not using Visual C#?

Framework v1.1 or beta 2.0?

[endo]

Is this likely to be the problem, my visual c# may be a little out of date - i been away from coding for a bit

.net framework 1.0 version 1.0.3705

[BMJ]

Wow, I'm very sorry I should have mentioned this, Console.Clear() and Console.ReadKey() are Framework version 2 members.

I've become used to version 2 already.


You could always download http://lab.msdn.microsoft.com/expres...p/default.aspx if you're willing to use the beta Framework.
