New Class

bagzli

Hey guys,

I added a class to my project and called it MyCustomClass, now in my main class I initialize it by saying

MyCustomClass test = new MyCustomClass;

What I am trying to do is when I create this class I want it to automatically run a default method that will do bunch of stuff.

with java I had a Main method that will happen whenever a class is created, I am trying to figure out what this method is with C# and how do I create it. So if you are familiar with java I am looking for public static void main(String [], args) method.

Yeah its a really dumb question, I just couldn't find the answer on google...

Thanks for the help.

Accepted answer
The Main() method in both Java and C# is a static method which runs automatically when an application starts executing.

If you want a method to run automatically when you create an object of your class, then you need to call it from the constructor. For example:

using System;

class MyCustomClass
{
private void DefaultMethod()
{
Console.WriteLine("Default Method called");
}

public MyCustomClass() // constructor
{
DefaultMethod();
}
}

class Program
{
// execution starts here
static void Main(string [] args)
{
MyCustomClass test = new MyCustomClass();
Console.ReadKey();
}
}

Cool, thanks for the answers. I'm actually using form, since I am building an actual program to be used later on.

Cheers,

Yes, it's almost the same - a slight difference is that in Java the main() method always begins with a lower case letter whereas in C# it must begin with an upper case latter.

Console.ReadKey() simply waits for the user to press a key. If (as most folks do) you're running a console application in debug mode using Visual Studio, then you'll find that the console window will close before you've had time to read the output. Adding Console.ReadKey() at the end of the program is one way to prevent this from happening.

oh wow, so it is exactly the same as in java? Also what does Console.readkey do?
