Help with using SteamWriter

Question

Hey guys,

I'm using steamwriter to write X and Y coordinates on mouse click to a text file. It does work but when I click more than once the coordinates in the text file are overwritten with the new coordinates. This is probably a simple question but how do I get it to write all new coordinates to a new line?

Here's my code:

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.IO;



namespace WindowsFormsApplication1

{

    public partial class Form1 : Form

    {

        public Form1()

        {

            InitializeComponent();

        }



        private void Form1_MouseClick(object sender, MouseEventArgs e)

        {

            string path = @"C:\coordinates.txt";

            StreamWriter sw = new StreamWriter(path);

            string bufferOne = ("X = " + e.X + ", Y = " + e.Y);

            sw.WriteLine(bufferOne);

            sw.Close();

            sw.Dispose();
          
        }

    }

}

Cheers!
