c# - How can I format a date in RFC format? -


i need format date in rfc format rss feed. have tried taking date , adding following:

.tostring("ddd, dd mm yyyy hh:mm:ss zzz")

however seems not valid. great! end result need is, example, mon, 01 jan 2013 gmt

your question bit confusing because example lacks time (but has time-zone). nevertheless, try using mmm month:

.tostring("ddd, dd mmm yyyy hh:mm:ss zzz")

if don't want time, omit section string:

.tostring("ddd, dd mmm yyyy")

but since mentioned you're generating string rss feed, use the "r" format specifier generate rfc1123-format date / time string:

.tostring("r")

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!
