The given System.Uri cannot be converted into a Windows.Foundation.Uri

Question

I\'m trying to programmatically load a BitmapImage in a XAML Metro app. Here\'s my code:

var uri = new Uri(\"/Images/800x600/BackgroundTile.bmp\", UriKind.Re         


        

Answer 1

This would work in XAML but would not work in code... so each control or page has a BaseUri property which you can use to build the proper uri for assets... here is an example:

    imageIcon.Source = new BitmapImage(new Uri(this.BaseUri, "Assets/file.gif"));

// Or use the base uri from the imageIcon, same thing

    imageIcon.Source = new BitmapImage(new Uri(imageIcon.BaseUri, "Assets/file.gif"));

also you would need to set the build action to "Content" rather than Embedded Resource... otherwise you need to use the ms-resource:// protocol.

Answer 2

In case you're still having issues or are being asked to find an app to open the link, are you trying to use a WebView? If so, try using ms-appx-web instead of ms-appx.

An example:

this.webBrowser.Navigate(new Uri("ms-appx-web:///level/level/level/index.html"));

Also note the lack of the URIKind parameter--evidently not needed at all in these instances.

(I believe you may need to vary the leading forward slashes depending on your reference)

Answer 3

In the Consumer Preview, the correct URL format has apparently changed to ms-appx:/Images/800x600/BackgroundTile.bmp

Answer 4

Judging from the documentation for Windows.Foundation.Uri, it looks like WinRT doesn't support relative URIs. I tried a pack:// URI, but that gave me a UriFormatException, so apparently that's not the way to do it in WinRT either.

I found the answer on this thread: MS invented yet another URI format for WinRT resources. This works:

new Uri("ms-resource://MyAssembly/Images/800x600/BackgroundTile.bmp")

Note that you don't add your actual assembly name -- the MyAssembly part is literal text.

Answer 5

You will need to use the page's BaseUri property or the image control's BaseUri property like this:

//using the page's BaseUri property
BitmapImage bitmapImage = new BitmapImage(this.BaseUri,"/Images/800x600/BackgroundTile.bmp");
image.Source = bitmapImage;

or

//using the image control's BaseUri property
image.Source = new BitmapImage(image.BaseUri,"/Images/800x600/BackgroundTile.bmp");

you can see the reason and solution here

Answer 6

MVVM ;)

    public static ImageSource SetImageSource(string uriPath)//.com/image or some path
    {
        // this method very good for mvvm ;)
        try
        {   
            //In Model - public ImageSource AccountPhoto { get; set; } 
            //AccountPhoto = SetImageSource("some path");
            return return new BitmapImage()
            {
                CreateOptions = BitmapCreateOptions.IgnoreImageCache,
                UriSource = new Uri(uriPath)
            };
        }
        catch
        {
            Debug.WriteLine("Bad uri, set default image.");
            return return new BitmapImage()
            {
                CreateOptions = BitmapCreateOptions.IgnoreImageCache,
                UriSource = new Uri("ms-appx:///Avatar/Account Icon.png")
            };
        }
    }
