Subject [jira] [Resolved] (CB-938) Need to pass more complex objects over the bridge
Date Tue, 24 Jul 2012 19:19:35 GMT


Jesse MacFadyen resolved CB-938.

    Resolution: Won't Fix

This is a limitation of the Silverlight JSON serialization, adding a 300 kb library dependencies
is not a reasonable solution.
Working around the specific issue mentioned involves url encoding the FileTransfer params
object, it can simply be passed as a string.

> [WP7] Passing more complex objects over the bridge... Currently won't work. Basically
the DataContractJsonSerializer .NET object that we employ to parse JSON on the native side
can't parse nested objects in JSON. The DataContract stuff is supposed to make it easy to
cast the various JSON values to .NET types. In the case of a nested object with dynamic keys,
that you can't model ahead of time, we tried using a Dictionary type on the native side. This
won't work [1].
> This came up when deserializing FileTransfer upload options because they have a nested
"params" object that house dynamic &key=value URL parameters to send with the HTTP request.
Not sure if it happens in other spots.
> Anywho, one potential solution is to explicitly convert nested objects such as these
to a dumber structure. In the SO thread [1] they suggest having an array of {key:"known1",value:"foo"}
pairs replace the objects.
> The native side could parse that.
> Another option is to use the library [2]. MIT license. 300-ish kb .dll.
> The stock System.Json namespace that is available in .NET and has better capabilities
is not available on Windows Phone.
> Any other solutions/ideas/comments/thoughts?
