Load image from url to ImageView - C#

Load image from url to ImageView - C#

You can load an image from a URL into an ImageView in C# using the System.Net.WebRequest and System.IO namespaces. Here's an example:

using System.Net; using System.IO; // ... string imageUrl = "https://example.com/image.jpg"; WebRequest request = WebRequest.Create(imageUrl); using (WebResponse response = request.GetResponse()) { using (Stream stream = response.GetResponseStream()) { Bitmap bitmap = new Bitmap(stream); imageView.Image = bitmap; } }

In this example, the imageUrl variable contains the URL of the image that you want to load into the ImageView. A WebRequest is created for the URL using the WebRequest.Create() method. The GetResponse() method is called on the request to get a WebResponse.

Inside a using block, the GetResponseStream() method is called on the WebResponse to get a Stream that contains the image data. The Bitmap class is used to create a bitmap from the stream, which is then assigned to the Image property of the ImageView.

Note that this code should be run on a separate thread, such as a Task, to avoid blocking the UI thread while the image is being loaded.
