Programmatically set the Source of an Image (XAML)

Programmatically set the Source of an Image (XAML)

To programmatically set the source of an Image element in XAML using C#, you can use the BitmapImage class to create a new image source and set it as the Source property of the Image element.

Here's an example of how to set the source of an Image element in XAML using C#:

using System; using System.Windows; using System.Windows.Controls; using System.Windows.Media.Imaging; ... // Get the Image element from the XAML file Image image = ...; // Create a BitmapImage object from a file path BitmapImage bitmap = new BitmapImage(new Uri(@"C:\path\to\image.jpg")); // Set the BitmapImage as the Source of the Image element image.Source = bitmap;

In this example, we first get the Image element from the XAML file.

We then create a new BitmapImage object by passing a file path to the constructor. You can also create a BitmapImage object from other sources, such as a stream or a byte array.

Finally, we set the BitmapImage object as the Source property of the Image element. The Image element will display the image from the specified source.
