How to programmatically set the Image source

问题

When the Image's Source property is set the following way, the picture is taken from /Images/down.png.

How would I do the same thing programmatically?

<Image x:Name="myImg" Source="/MyProject;component/Images/down.png" />

The following would not work, since Image.Source property is not of a string type.

myImg.Source = "/MyProject;component/Images/down.png";

回答1:

Try this:

BitmapImage image = new BitmapImage(new Uri("/MyProject;component/Images/down.png", UriKind.Relative));

回答2:

myImg.Source = new BitmapImage(new Uri(@"component/Images/down.png", UriKind.RelativeOrAbsolute));

Don't forget to set Build Action to "Content", and Copy to output directory to "Always".

回答3:

Try to assign the image that way instead:

imgFavorito.Source = new BitmapImage(new Uri(base.BaseUri, @"/Assets/favorited.png"));

回答4:

{yourImageName.Source = new BitmapImage(new Uri("ms-appx:///Assets/LOGO.png"));}

LOGO refers to your image

Hoping to help anyone. :)

Use asp:image

<asp:Image id="Image1" runat="server"
           AlternateText="Image text"
           ImageAlign="left"
           ImageUrl="images/image1.jpg"/>

and codebehind to change image url

Image1.ImageUrl = "/MyProject;component/Images/down.png";

try this

PictureBox picture = new PictureBox
        {
            Name = "pictureBox",
            Size = new Size(100, 50),
            Location = new Point(14, 17),
            Image = Image.FromFile(@"c:\Images\test.jpg"),
            SizeMode = PictureBoxSizeMode.CenterImage
        };
p.Controls.Add(picture);
