heya guys, i need some help in C#

Recently been learning it as you know but heres the problem i have

When Using Visual Studio how do i create a small application and execute it within the CMD Area.

Because it starts with a "Form" as basic.

If you can just let me know how to create a simple hello world application and execute it within CMD as an exe would be HUGE Help

Thanks in advanced

You have to create it as a console application I think.

mare for console..use C++..C# console is shit..u hve to type loads..

C++ is awsome..xd

[Hyperz]

Sniper, you're an idiot for saying that no offense. You do realize they both use Win32 under the hood? And that you can do the exact same stuff with C# as you would with C++ but with less code? Seriously...

@Lite, as others said, create a console application.

lmfao @sniper. here - ill make one for you.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication3
{
    class Program
    {
        static void Main(string[] args)
        {
            DoWork("hello world.");
        }

        static void DoWork(string input)
        {
            Console.WriteLine(input);
            Console.WriteLine("hello again!");
            Console.Read();
        }
    }
}

Ok net me just get this straight.

void = does not return anything
the function Main is a constructor.
Console.WriteLine sends text to the CMD
Console.Read() waits for a user input. ?

and no matter the class named Program is executed first ?

[jayfella]

indeed.

you can also do:

static object[] myObject(string input)
{
// blah blah
// do some stuff
return new object { "some", "stuff", "here" };
}

static void hello()
{
object[] myNewObject = myObject("testing");

int test = myNewObject.Length; //get the size of the array
string a = myNewObject[0];
string b = myNewObject[1];
string c = myNewObject[2];
} 

[Hyperz]

void = returns nothing
Main = the program's "entry point" (where the execution begins)
Read(); = reads a char and pause the console preventing it from instantly closing
Static = members/functions are accessible globally without having to new up an instance of the class

[litewarez]

ok but do the objects HAVE to be static ?

in PHP This means that the object does not need to be initiated but you cant use the special variable $this / this ??

hyper Answered thanks all, im getting there
