Static function explained

[robert201]

Hello,

I am just writing simple threading program in C# program, I am coming from VB.Net and just wondering why my WriteY() function has to be a static. I through this could be public or private.

Can anyone explain why it has to be a static.

Many thanks,

Steve

using System;
using System.Collections.Generic;
using System.Text;
using System.Threading;

namespace App1
{
    class Program
    {
        static void Main(string[] args)
        {
            Thread t = new Thread(WriteY);
            t.Start();
            while (true) Console.Write("X");
        }

        static void WriteY()
        {
            while (true)
                Console.Write("Y");
        }
    }
}

your main method is static. If your main method creates an instance of an object then you can use non-static methods. A static method can be both public or private it's just how you access it.

For example

public class Writer
{
public static void WriteY()
{
Console.WriteLin("Y");
}

public void WriteZ()
{
Console.WriteLine("Z");
}
}

From your main method you have to access those 2 properties in different ways.

static void Main()
{
Writer.WriteY(); //This is a static method
//Writer.WriteZ() is not available

Writer mywriter = new Writer();
mywriter.WriteZ(); //This is a non-static method
//mywriter.WriteY() is not available
}


I hope that gives you some light
