C# Image Download

Introduction

I don't think this small piece of code needs a big introduction. Easy to use for anyone who just started C# programming.

Background

One day I just rattled around and thought to myself it would be nice to have a small easy helper method/class that makes it easy to download images from the web. Here it is. Ready and easy for use.

Using the code

I left out namespace on purpose because I am sure everyone wants to write their own namespace anyway.

Here is the code just to paste into a new class in your IDE:

using System;
using System.Drawing;
using System.Drawing.Imaging;
using System.IO;
using System.Net;

public class DownloadImage {
  private string imageUrl;
  private Bitmap bitmap;
  public DownloadImage(string imageUrl) {
    this.imageUrl = imageUrl;
  }
  public void Download() {
    try {
      WebClient client = new WebClient();
      Stream stream = client.OpenRead(imageUrl);
      bitmap = new Bitmap(stream);
      stream.Flush();
      stream.Close();
    }
    catch (Exception e) {
      Console.WriteLine(e.Message);
    }
  }
  public Bitmap GetImage() {
    return bitmap;
  }
  public void SaveImage(string filename, ImageFormat format) {
    if (bitmap != null) {
      bitmap.Save(filename, format);
    }
  }
}

Hope this makes it easier for people.
