Question

I’m instancing a Uri to be used as an image source but the string (file path) I’m providing is invalid. I understand why – it’s because I’m using a relative path:

"Resources/Images/" + draggedAct.Category.ToLower() + ".png"

When I had this problem in asp .net I used Server.MapPath(imageString) to resolve the full path but I don’t know the equivalent in WPF.

Thanks a lot,

Dan

use the pack uri syntax (see msdn: http://msdn.microsoft.com/en-us/library/aa970069%28v=vs.85%29.aspx):

"pack://application:,,,/Resources/Images/"+ draggedAct.Category.ToLower() +".png"

// Absolute URI (default)
Uri absoluteUri = new Uri("pack://application:,,,/Resources/Images/"+ draggedAct.Category.ToLower() +".png", UriKind.Absolute);

or:

// Relative URI
Uri relativeUri = new Uri("/Resources/Images/"+ draggedAct.Category.ToLower() +".png", UriKind.Relative);
