display image from the internet in a PictureBox (C#)

Question

Hi all. Im trying to display images from the web into a picturebox control. when the form loads, i'd like for the pictureBox control to read a URL from a textbox control and load the image. i found the VB equivalent code to do this but im a newbie and cant translate it into C#:

PictureBox1.Image = New System.Drawing.Bitmap(New IO.MemoryStream(New System.Net.WebClient().DownloadData(TextBox1.Text)))  // Assumes there is a textbox called textbox1 and a picturebox called picturebox1 on a form. Textbox1.text should be the URL of the picture.

Is there an easier way to go about this? Any help is appreciated. Thanks in advance

Answer 1

Hi,

how about

pictureBox1.ImageLocation = textBox1.Text;

or

pictureBox1.Load(textBox1.Text); ?

Hi Andrej. Thanks for the quick replay. for some reason, the ImageLoaction and Load property arent available to me. they dont appear for me =(

Answer 3

Hi,

you're probably using framework 1.1... That method and property are available with 2.0 only. So, to translate your code:

pictureBox1.Image = new System.Drawing.Bitmap(new System.IO.MemoryStream(new System.Net.WebClient().DownloadData(textBox1.Text)));

thanks again, im getting an error now when i try to build the solution:

The type or namespace name 'IO' could not be found (are you missing a using directive or an assembly reference?)

i dont understand how im getting this error seeing as how i used the using directive for the IO namespace  :

using System;

using System.Drawing;

using System.Collections;

using System.ComponentModel;

using System.Windows.Forms;

using System.Data;

using System.Data.OleDb;

using System.IO;

have any idea what coule be the problem? thanks in advance

WebRequest req = WebRequest.Create("http://www.google.co.il/Picture.jpg");
Stream stream = req.GetResponse().GetResponseStream();
