Adding Image to wpf

问题

I want to add an Image dynamically to the wpf application.

What I have tried :

            Image img = new Image();
            img.Height = 100;
            img.Width = 100;
            img.Visibility = Visibility.Visible;

            Thickness th = new Thickness(100, 100, 0, 0);
            img.Margin = th;

            string strUri2 = String.Format(@"pack://application:,,,/MyFirstWPF;component/Images/tt.jpg");
            img.Source = new BitmapImage(new Uri(strUri2));

I know, the image won't display unless I add it to the Content.

this.Content=img;

but with this the existing controls(shapes) on the app are lost.

Now, my question is how to add the image to the content without losing existing controls from the app.

回答1:

When you are going to load and show an image dynamically, you still need to think about the layout of your application. I would suggest to add an (initially empty) Image control in XAML (for example in a Grid), and later set the Source property of this control in code.

<Grid>
    ... other controls ...
    <Image Name="img" Grid.Row="..." Grid.Column="..."
           Width="100" Height="100" Margin="100,100,0,0"/>
</Grid>

Set Source in code:

var uri = new Uri("pack://application:,,,/MyFirstWPF;component/Images/tt.jpg");     
img.Source = new BitmapImage(uri);

回答2:

by default the window content is a grid so try

(this.Content as Grid).Children.Add(img);
