c# - Is processes threads (or whole process) suspended -


i check if processes' threads (the whole process) suspended. i'm obtaining each process thread code:

var threads = proc.threads; (int x = 0; x < threads.count; x++) { var thread = threads[x];

however system.diagnostics.threadstate doesn't contain suspended, system.threading.threadstate does. how convert system.diagnostics.threadstate system.threading.threadstate, or other method check it? i'm not trying suspend/resume them, want know how process hacker/process explorer that.

microsoft made big mistake in .net version 1.0, added thread.suspend() , resume() methods. methods abused, programmers used them implement thread synchronization. entirely inappropriate. problem usually worked. call suspend() @ unlucky time , you'll freeze thread while buried inside windows call, holding global lock. , causing entire program deadlock.

it not design mistake made, synchronized method on collection classes quite disaster well. misinterpreted "returns thread-safe collection".

live , learn, got fixed in .net 2.0. 1 big overhaul thread may not operating system thread anymore, never got implemented. explains why there two threadstate enumerations, 1 thread (the .net version) , processthread (the operating system version). , closed loophole on programmers abusing suspend/resume, methods declared obsolete. , closed backdoor well, can't find out processthread thread suspended.

feature, not bug. don't make same mistake, knowing thread suspended useless knowledge, may not suspended anymore microsecond later.

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!
