Source Code Base64 Images Convert (Form1.Cs)
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 Base64ImagesConverter {
public partial class Form1 : Form {
public Form1() {
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e) {
DialogResult dr = openFileDialog1.ShowDialog();
try {
textBox1.Text = openFileDialog1.FileName;
} catch (Exception x) {
MessageBox.Show(x.Message);
}
}
private void button2_Click(object sender, EventArgs e) {
if (textBox1.Text == "") {
MessageBox.Show("No path spesified");
textBox1.Focus();
}
else {
byte[] imagearray = System.IO.File.ReadAllBytes(textBox1.Text);
string createBase64 = Convert.ToBase64String(imagearray);
richTextBox1.Text = createBase64;
}
}
private void button3_Click(object sender, EventArgs e) {
if (richTextBox1.Text !="") {
// we can create base64 functions
pictureBox1.Image = Base64toImage(richTextBox1.Text);
} else {
MessageBox.Show("Paste Base 64 string First");
richTextBox1.Focus();
}
}
public Image Base64toImage(string base64string) {
// Convert Base64 String to byte[]
byte[] imagesByte = Convert.FromBase64String(base64string);
System.IO.MemoryStream ms = new System.IO.MemoryStream(imagesByte, 0 , imagesByte.Length);
// Convert byte[] to Image , based on @Crulex comment, the below line has no need since MemoryStream already initialized
ms.Write(imagesByte, 0 , imagesByte.Length);
Image image = Image.FromStream(ms, true);
return image;
}
private void button4_Click(object sender, EventArgs e) {
Clipboard.Clear();
Clipboard.SetText(richTextBox1.Text.ToString());
MessageBox.Show("Copied to clipboard!");
richTextBox1.Clear();
}
private void button5_Click(object sender, EventArgs e) {
richTextBox1.Text = Clipboard.GetText();
}
private void button6_Click(object sender, EventArgs e) {
this.Close();
}
}
}
