c# - MEF doesn't discover exports in assembly loaded from byte[] -


i trying use mef application accepts plugins loaded database. when try creating new assemblycatalog , pass in dynamically created assembly, mef appears unable discover exports.

assembly = assembly.load(new assemblymover().getassemblybytes("plugin1")); assemblycatalog c = new assemblycatalog(a);

assemblycatalog doesn't contain parts (but should).

if move exportable class current assembly run following:

assemblycatalog c = new assemblycatalog(assembly.getexecutingassembly());

mef discovers part fine (which assume).

the interface defined in shared assembly:

public interface iplugin {     string name { get; } }

the assembly plugin1 has single class:

[export(typeof(iplugin))] public class testplugin1 : iplugin {     public string name     {         { return "plugin1"; }     } }

i thought mef used reflection discover parts, verified assembly loaded correctly , contained class testplugin1.

foreach (type t in a.gettypes())         {             messagebox.show(t.name);         }

any thoughts?

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
