I wish this help you
Set your images as Resource i.e. Set your Image Properties => Build Action = Resource and Copy to output directory = No
code :
    public sealed class ImageConverter : IValueConverter
    {
        public object Convert(object value, Type targetType,
                              object parameter, CultureInfo culture)
        {
            try
            {
                return new BitmapImage(new Uri((string)value));
            }
            catch
            {
                return new BitmapImage();
            }
        }

        public object ConvertBack(object value, Type targetType,
                                  object parameter, CultureInfo culture)
        {
            throw new NotImplementedException();
        }
    }

Bind Xaml bitmap image

hope this fix your issue If you really want to set it from C# code and not from inside XAML, you should use this easy solution described further on the MSDN reference:
code :
string path = "Resources/Untitled-100000.png";
BitmapImage bitmap = new BitmapImage(new Uri(path, UriKind.Relative));
image.Source = bitmap;
<Image x:Name="image" ... />
string path = "SplashDemo.Resources.Untitled-100000.png";
using (Stream fileStream = GetType().Assembly.GetManifestResourceStream(path))
{
    PngBitmapDecoder bitmapDecoder = new PngBitmapDecoder(fileStream,
        BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.Default);
    ImageSource imageSource = bitmapDecoder.Frames[0];
    image.Source = imageSource;
}

How to know whether drawable of image view from bitmap or resources

this one helps. , You can not check like that... but this approach may help you...
code :
    private void setImage(Drawable drawable,boolean isFromResource) {
        imageView.setImageDrawable(drawable);
        imageView.setTag(isFromResource);
    }

    private void recycle() {
        Object object = imageView.getTag();
        if(object != null && object instanceof Boolean) {
            boolean isFromResource = (Boolean) object;
            if(!isFromResource) {
                Drawable drawable = imageView.getDrawable();
                if(drawable != null && drawable instanceof BitmapDrawable) {
                    BitmapDrawable bitmapDrawable = (BitmapDrawable) drawable;
                    Bitmap bitmap = bitmapDrawable.getBitmap();
                    bitmap.recycle();
                    imageView.setImageDrawable(setToNewDrawable);
                }
            }
        }
    }

Deserialize bitmap image and compare it with images in resources


By : heyitslujan

I hope this helps . I ended up just storing a string to signify which image to display. The Bitmap property just references which string to use. I never serialize the bitmap.
code :
[XmlIgnore]
public Bitmap UpToDate
{
    get
    {
        //Only null if file entered is invalid. This causes image to be blank
        if (UpToDateString == null) 
            return null;

        //Translates from the resource specified to the bitmap object being used
        var resourceObject = Resources.ResourceManager.GetObject(UpToDateString);
        return (Bitmap) resourceObject;
    }
}

//This holds the reference for which resource image to use
[XmlElement("UpToDate")]
public string UpToDateString { get; set; }

Bind Dynamically Created Bitmap object to Image in WPF


By : A. Rosen

With these it helps The only thing you need to do is convert the Bitmap to an ImageSource which can be used in the Image control. So in your binding you can add a Converter which accomplishes that. The implementation of the conversion is likely to be found in the answers to this question.
(If you have a chance to work directly with BitmapImage (WPF) instead of Bitmap (WinForms) that might be quite a good idea)
