Show image from URL with Xamarin.Forms

Show image from URL with Xamarin.Forms

To show an image from a URL in Xamarin.Forms, you can use the Image control and set its Source property to a URI.

Here's an example of how to do this:

<Image Source="https://example.com/image.png" />

In this example, we're setting the Source property of the Image control to the URL of an image.

Alternatively, you can set the Source property of the Image control to an UriImageSource object:

var imageSource = new UriImageSource { Uri = new Uri("https://example.com/image.png") }; var image = new Image { Source = imageSource };

In this example, we're creating a new UriImageSource object with the URL of an image and setting it as the source of the Image control.

Note that you may need to set the WidthRequest and HeightRequest properties of the Image control to ensure that the image is displayed at the correct size. You may also need to set the Aspect property of the Image control to control how the image is resized to fit the available space.
