C＃：当用户单击按钮时如何查看图像？

Question

I've seen many different versions of the same answer, none of which have solved my problem. I'm using a WPF and I want an image to view when the user clicks on a button "hint". Here's the code so far:

    void Hint_Click(object sender, RoutedEventArgs e)
    {
        Label.Content = "Yes";
        BitmapImage RealTrump = new BitmapImage(new Uri("RealTrump", UriKind.Relative));
    }

It's a jpeg image and is saved within the project file so the directory is just "RealTrump". When I run through compiler and click the button it just views the label and not the image.

Here's the XAML code, I really don't know what to do with it as I'm still pretty new to c# and programming in general:

<Image x:Name="RealTrump" HorizontalAlignment="Left" Height="100" Margin="381,44,0,0" VerticalAlignment="Top" Width="97"/>

I'm on Visual Studio 2013 if that helps.

Answer 1

While you have given your label the name RealTrump you've created a local variable of the same name in the click event handler.

If you simply remove the type declaration and set the image source like this:

void Hint_Click(object sender, RoutedEventArgs e)
{
    Label.Content = "Yes";
    RealTrump.Source = new BitmapImage(new Uri("pack://application:,,,/Images/RealTrump.jpg", UriKind.Relative));
}

The image should be displayed. (You may have to adjust the path slightly depending on exactly where it is relative to your source.
