memory - .net - Signal to the Garbage Collector than an object is ready for removal? -


i reading on performance of .net garbage collector, , i'm building set of inter-referencing classes data model. have implemented delete() methods dereference object connected objects, ensuring object collectable.

while not know if issue application, got thinking happen objects promoted later generations , deleted. possible remain in memory long time.

is possible tell garbage collector particular object should 'demoted' , freed during next gen0 collection?

one of optimisations possible garbage collector leave objects unreferenced objects in memory long possible deferring collection until absolutely necessary. can yield fewer collections , mutualise cost of collection across more objects/memory.

is problem if objects remain in memory long time after being dereferenced? if machine has enough free memory , application's footprint after dereferencing not growing there downside?

the collection cost guaranteed cost whereas cost of using memory not - may or may not impact program/other programs. key point of optimisation give cost in exchange uncertain one.

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!
