Threads

i am a beginner to C# i am trying to type some code for threading, and now i came across this error:"A field initializer cannot reference the non-static field, method, or property 'Thread_test.Form1.task()' "

and here is my code in c#:

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Windows.Forms;

using System.Threading;

namespace Thread_test

{

public partial class Form1 : Form

{

Thread process = new Thread(new ThreadStart(task));

public void task()

{

int a = 0;

for (; ; )

{

a = a + 1;

textBox1.Text = Convert.ToString(a);

}

public Form1()

{

InitializeComponent();

}

private void Form1_Load(object sender, EventArgs e)

{

}

private void button1_Click(object sender, EventArgs e)

{

process.Start();

}

Thanks for your help !-)

Your code needs to be modified as follows:

public partial class Form1 : Form
        {

            Thread process;

            public void task()
            {
                int a = 0;
                for (; ; )
                {
                    a = a + 1;
                    textBox1.Text = Convert.ToString(a);
                }
            }

            public Form1()
            {
                InitializeComponent();
                process = new Thread(new ThreadStart(task));
            }

            private void Form1_Load(object sender, EventArgs e)
            {

            }

            private void button1_Click(object sender, EventArgs e)
            {
                process.Start();
            }
        }
