A I said,in this article we will create a picture viewer in C#.Let's start by creating a new Windows Forms Aplication Project and add a button,an openfile dialog and a picturebox to our form.



Now,it should look like this,but you can design it however you want.

The first part is finished,so let's start writing the code.

In my case

opnbutton = openbutton
pictureBox1 = the picturebox
openFileDialog1 = the openfile dialog

This is the code

  1. using System;
  2. using System.Collections.Generic;
  3. using System.ComponentModel;
  4. using System.Data;
  5. using System.Drawing;
  6. using System.Linq;
  7. using System.Text;
  8. using System.Windows.Forms;
  9. using System.IO;
  10. namespace BeHe_Picture_Viewer
  11. {
  12. public partial class Form1: Form
  13. {
  14. public string path;
  15. public Form1()
  16. {
  17. InitializeComponent();
  18. }
  19. private void opnbutton_Click(object sender, EventArgs e)
  20. {
  21. openFileDialog1.ShowDialog(); //Shows the dialog
  22. if (openFileDialog1.ShowDialog() == System.Windows.Forms.DialogResult.OK)
  23. {
  24. try
  25. {
  27. pictureBox1.Load(openFileDialog1.FileName); //Loads the selected file
  28. }
  29. catch
  30. {
  31. MessageBox.Show("Error opening file"); //Sets the erorr
  32. }
  33. path = Path.GetDirectoryName(openFileDialog1.FileName); //Gets the current path
  34. this.Text = "BeHe Picture Viewer - " + path;
  35. }
  36. }
  37. }
  38. }
Remember,this is for beginners.I created something similar that can open pictures from the same folder(next and prev button),using System.IO,but this could be a liitle hard at the beginning.

Thanks you guys.

Enjoy.
