Thread: Open a Form C#

I have just created "WindowsFormsApplication1".
To this I have "Form1".
I have Added a New Item to this project: "Form2"

So I have 2 Forms.

Now I have created a button on "Form1". With this button I want to open
"Form2".

I have never done this before so I have no idéa where to start.

Code for "Form1"

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;

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {

        }
    }
}

"Form2"

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;

namespace WindowsFormsApplication1
{
    public partial class Form2 : Form
    {
        public Form2()
        {
            InitializeComponent();
        }

        private void Form2_Load(object sender, EventArgs e)
        {

        }
    }
}

What will I do with this code now, the only thing I know is that this possible have something to do in order to open "Form2" ?.

Code:

Form2.Show();

Thank you. This did work but as you said it open a lot of window when clicking many times.. I will work with this and see what could be found out...

Code:

On button click:
 - if form2 does not exists 
       create form2 instance

  show form2 instance
