An image is not loaded in BitmapImage

  • 772

I'm trying to load images at runtime and each one is selected by a switch:

seguimiento.tareaA = new Image();
switch (rowTarea["idTareaTipo"].ToString())
                    {
                        case "f7f91a6f-24a2-1034-b505-d1f8671a4f3f"://Seguimiento
                            Uri uri = new Uri("pack://application:,,,/Resources/Seguim_Chico__0000_6_Pago_Rojo.png");
                            BitmapImage bmp = new BitmapImage(uri);
                            seguimiento.tareaA.Source = bmp;
                            break;

When running the program, it does not give errors but the images are not loaded either... I tried to debug and the only strange thing I found was an error in the Metadata when creating the BitmapImage:enter image description here

How can I fix the error or make the image display?

c#

    At some point I had that problem and found a post on the original SO

    The trick is to put the origin between the methods BeginInit()andEndInit()

    BitmapImage logo = new BitmapImage();
logo.BeginInit();
logo.UriSource = new Uri("pack://application:,,,/AssemblyName;component/Resources/logo.png");
logo.EndInit();

    The explanation is in the official documentation :

    The initialization of the property must be done between the BeginInit and EndInit calls. Once the BitmapImage has been initialized, property changes are ignored.

  2. Try this:

    seguimiento.tareaA = new Image();
switch (rowTarea["idTareaTipo"].ToString())
{
    case "f7f91a6f-24a2-1034-b505-d1f8671a4f3f"://Seguimiento
    BitmapImage bi3 = new BitmapImage();
    bi3.BeginInit();
    bi3.UriSource = new Uri("pack://application:,,,/Resources/Seguim_Chico__0000_6_Pago_Rojo.png");
    bi3.EndInit();
    seguimiento.tareaA.Source = bi3;
    break;
