Question

I experienced a strange behavior for some queryStrings for my secondary tiles.
the string is the following:

 "/MainPage.xaml?link=" + "touch.facebook.com/home.php?refsrc=http://touch.facebook.com/home.php"

even if the second part is Uri.EscapeUriString()’ed or not, the app isn’t starting through the secondary tile at all. it’s instantly crashing, before loading anything.

is there anything I have to consider about queryStrings?

thanks

Answer 1

The second ? needs to be an &

Edit: URI’s have a given form page ? argument = value & argument = value & ... etc

Parse your uri before you try using it:

string uri = "/MainPage.xaml?link=" + "touch.facebook.com/home.php?refsrc=http://touch.facebook.com/home.php";

string[] array = uri.Split('?');
if (array.Length > 2)
    uri = array[0] + "?" + string.Join("&", array.Skip(1).ToArray());
