[c#] Change image source in code behind - Wpf

I need to set image source dynamically, please note my image is in somewhere on the Network, here is my code

BitmapImage logo = new BitmapImage();
logo.BeginInit();
logo.UriSource = new Uri(@"pack://application:,,,\\myserver\\folder1\\Customer Data\\sample.png");
logo.EndInit(); // Getting the exception here
ImageViewer1.Source = logo;

Exception:

The URI prefix is not recognized

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");

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

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

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 are all wrong! Why? Because all you need is this code to work:

(image View) / C# Img is : your Image box

Keep this as is, without change ("ms-appx:///) this is code not your app name Images is your folder in your project you can change it. dog.png is your file in your folder, as well as i do my folder 'Images' and file 'dog.png' So the uri is :"ms-appx:///Images/dog.png" and my code :

private void Button_Click(object sender, RoutedEventArgs e)
    {
         img.Source = new BitmapImage(new Uri("ms-appx:///Images/dog.png"));
    }
