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();

---

Code:

---

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace CboardExample {
 
  public partial class Form1 : Form {
    private Form form2instance;
    public Form1() {
      InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e) {
      this.form2instance = new Form2();
      this.form2instance.Show();
    }
  }
}

And form 2 is just an empty form...

So basically before applying Show to some object , you first need a form2 instance available.

This should be in the C# board instead of the windows programming form.

There is still something wrong though with the code above, just try to press the button multiple times and see what happens, up to you to fix that.

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
