Dynamic loading of images in WPF application

Loading images into a WPF window at runtime may seem complicated. This article delves into the process, addresses common issues, and provides code examples.

Load image from URI

In WPF, images can be loaded from a Uniform Resource Identifier (URI) or a stream. BitmapImageSupports URI and can be assigned directly through its constructor:

<code class="language-csharp">var uri = new Uri("http://...");
var bitmap = new BitmapImage(uri);</code>

Load image from local file

To load an image from a local file, use the file:// URI:

<code class="language-csharp">var path = Path.Combine(Environment.CurrentDirectory, "Bilder", "sas.png");
var uri = new Uri(path);</code>

Load image from assembly resource

For images embedded as assembly resources, use the Pack URI scheme:

<code class="language-csharp">var uri = new Uri("pack://application:,,,/Bilder/sas.png");</code>

Make sure the image's "Build Action" property in Visual Studio is set to "Resource".

Assign image source

After

obtains BitmapImage, assign it to the Image attribute of the Source control:

<code class="language-csharp">image1.Source = bitmap;</code>

Usage Example

The following is an example using resource images:

<code class="language-csharp">BitmapImage image = new BitmapImage(
    new Uri("pack://application:,,,/Resources/" + company + ".png"));
image2.Source = image;</code>

Follow these steps and you can easily dynamically load images into a WPF window.
