Change image source in code behind - Wpf

None of the methods worked for me as i needed to pull the image from a folder instead of adding it to the application. The below code worked:

TestImage.Source = GetImage("/Content/Images/test.png")

private static BitmapImage GetImage(string imageUri)
{
    var bitmapImage = new BitmapImage();
    
    bitmapImage.BeginInit();
    bitmapImage.UriSource = new Uri("pack://siteoforigin:,,,/" + imageUri,             UriKind.RelativeOrAbsolute);
    bitmapImage.EndInit();
    
    return bitmapImage;
} 

You just need one line:

ImageViewer1.Source = new BitmapImage(new Uri(@"\myserver\folder1\Customer Data\sample.png"));

None of the above solutions worked for me. But this did:

myImage.Source = new BitmapImage(new Uri(@"/Images/foo.png", UriKind.Relative));

The pack syntax you are using here is for an image that is contained as a Resource within your application, not for a loose file in the file system.

You simply want to pass the actual path to the UriSource:

logo.UriSource = new Uri(@"\\myserver\folder1\Customer Data\sample.png");
