c# - ASP.NET MVC Simple Controller Unit Test -


i'm trying learn unit testing, , have super simple class, unit test: 

public class homecontroller : controller {     public actionresult index()     {         return view(new homeviewmodel         {             logourl = this.url.content("~/images/product.png")        });     } }  [testmethod] public void index() {     assert.isnotnull(new homecontroller().index() viewresult); }

i'm getting null reference exceptions. it's related using this.url() without httpcontext in unit test, believe.

how can unit test pass while still using this.url()? i'm fine using moq. :)

the answer can found here example (gist): https://gist.github.com/johnnyreilly/4959924

here relating stack overflow question: asp.net mvc: unit testing controllers use urlhelper

both should on right tracks.

it comes down mocking httprequestbase , httpresponsebase can mock actual httpcontextbase, being used urlhelper class.

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!
