Menu inside console application

[Arjen]

Hello,

I have made a main class. (main.cs)
I also have made a menu class. (menu.cs)
The reason that I separate is is just for the code overview.

Now I want to see the menu calling from the main.
The problem is is that I don't want to make an object...
Is there not a way that I call the menu as procedure or function?

Thanks!

More information about my question.

using System;
namespace Test {
static void Main(string[] args) {
// How to get my menu??? like showmenu();

}
}

using System;
namespace Test
{
/// <summary>
/// Summary description for showMenu.
/// </summary>
public showmenu() {
// some code
}
}
Must this be public? static?

I just want to access it like I said above.

Thanks!

Well, you could implement static methods in your menu class and call
them, without having to make an instance of your menu class.

e.g.:

class Menu
{
public static StaticMethod()
{
}
}

//...

static void Main()
{
Menu.StaticMethod();
}

You can't do that in C# -- namespaces are for holding classes only.

You'd have to do something like this instead:

namespace Test
{

public class Menu
{
public static Show()
{
}
}

}

Note that the name has changed from "ShowMenu" to "Show", since "Show"
is implemented in the "Menu" class.

Then call this static method with: Menu.Show();

C# doesn't knows functions, procedures and contructors?

Thanks!

In Delphi (formerly known as Object Pascal), a function is a routine
that explicitly returns a value, and a procedure is a routine which
doesn't. I'm presuming this is what you mean here.

In C#, you can only define *methods*, which are functions or routines
of a class.

You can define either instance methods or static methods. Instance
methods are called upon an instance of a class, whereas static methods
aren't.

Static methods are, in a sense, functions/procedures which need to be
called with the *class name* as a prefix.

Here:

namespace MyNamespace
{

public class MyClass
{
public static void Procedure()
{
}

public static int Function()
{
}
}

You can call either of these like:

MyClass.Procedure();
MyClass.Function();

Note that you are *not* creating an instance of MyClass here, you are
simply calling its static methods.

As for constructors, C# has them, and their meaning is similar to
those of other languages:

public class MyClass
{
void MyClass()
{
Console.WriteLine("I am a constructor of MyClass!");
}
}

This is similar to the following Delphi code:

interface

type TMyClass = class
public
constructor Create;
end;

implementation

constructor TMyClass.Create;
begin
WriteLn("I am a constructor of TMyClass!");
end;

Thanks for your answer!
