How do I save the data in a winform

Question

See more:

I have designed a Winform in Visual Studio which has multiple tabs.

Some of the tabs have a textbox and some have both a textbox and a picturebox, with a button to upload images into the picturebox and the ability to enter text in the textbox.

What I would like to do is to be able to click "Save as.." and save it as some filename which then saves the data (text and images) and populates the tabs in the Winform with the saved data when I re-open the file at a later date.

I should state that I'm not a coder which is why I am here seeking help. The code below took a couple of days to write due to many hours spent reading through forums.

Any help on how to go about saving the data will be much appreciated.

What I have tried:

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

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

       
        private void Form1_Load(object sender, EventArgs e)
        {

        }

        

        private void ButtonTechSetup_Click(object sender, EventArgs e)
        {
            openFileDialog1.ShowDialog();
            string fileName = openFileDialog1.FileName;
            this.pictureBoxTechSetup.Image = System.Drawing.Image.FromFile(fileName);
        }

        private void ButtonTradeManagement_Click(object sender, EventArgs e)
        {
            openFileDialog1.ShowDialog();
            string fileName = openFileDialog1.FileName;
            this.pictureBoxTradeManagement.Image = System.Drawing.Image.FromFile(fileName);
        }

        private void ButtonBigPic_Click(object sender, EventArgs e)
        {
            openFileDialog1.ShowDialog();
            string fileName = openFileDialog1.FileName;
            this.pictureBoxBigPic.Image = System.Drawing.Image.FromFile(fileName);
        }

        private void SaveAsToolStripMenuItem_Click(object sender, EventArgs e)
        {
            
        }
    }
}

You can define a class holding all of this data and declare this class as serializable.

C#

[Serializable]
public class FormData
{
   public string TextBox1Data { get; set; }
   // ...
   public Image PictureBox1Data { get; set; }
   // ...
}

// Then, in form class
private void SaveButton_Click(object sender, EventArgs e)
{
   using (SaveFileDialog dialog = new SaveFileDialog())
   {
      if (dialog.ShowDialog(this) == DialogResult.OK)
      {
         using (FileStream fs = new FileStream(dialog.FileName, FileMode.OpenOrCreate))
         {
            FormData data = new FormData();
            data.TextBox1Text = textBox1.Text;
            // ...
            data.PictureBox1Data = pictureBoxTechSetup.Image;
            // ...
            BinaryFormatter formatter = new BinaryFormatter();
            formatter.Serialize(fs, data);
         }
      }
   }
}

private void LoadButton_Click(object sender, EventArgs e)
{
   using (OpenFileDialog dialog = new OpenFileDialog())
   {
      if (dialog.ShowDialog(this) == DialogResult.OK)
      {
         using (FileStream fs = new FileStream(dialog.FileName, FileMode.Open))
         {
            BinaryFormatter formatter = new BinaryFormatter();
            FormData data = (FormData)formatter.Deserialize(fs);
            textBox1.Text = data.TextBox1Text;
            // ...
            pictureBoxTechSetup.Image = data.PictureBox1Data;
            // ...
      }
   }
}
