Binding to Image Property

Question

Let's say I have the following dummy class:

public class Foo
    {
        public Image MyImage
        {
            get;
            set;
        }
    }

and I have the following in some XAML

<Image Source="{Binding Foo.MyImage}"/>

If I understand this correctly, this doesn't work because Source is expecting a URI string value for where MyImage is stored but in this case there is no URI because MyImage is in memory.

How can I get the above to work?

EDIT:

This is how MyImage is being created:

private void CreateBarCode(string bcValue)
    {
        Code128 bc128 = new Code128();
        bc128.HumanReadable = Code128.TextWhere.Below;
        this.MyImage = new Bitmap(bc128.Generate(bcValue)); 
    }

Via a method which takes a string value and returns a barcode which is in Bitmap format.

The Source property on the Image control is of type ImageSource. Your MyImage property has one of those accessible at MyImage.Source. So your xaml would look like

<Image DataContext={Binding Path=_anInstanceOfClassFoo} Source="{Binding Path=MyImage.Source}"/>

typically you don't set the DataContext directly, rather you'd let it inherit from parent controls. I only did that because in your example, your binding references the Foo class directly and not an instance
