c# - How to dispose an SmtpClient in .NET 3.5? -


i using smtpclient send mail. how can dispose smtpclient. using .net 3.5.

 try      {          smtpclient.send(message);          log.writespeciallog("smtpclient mail sending try success", "");      }       catch (exception ee)      {          log.writespeciallog("smtpclient mail sending try failed : " + ee.tostring(), "");          return false;      }

for .net 3.5, not being able proper dispose smtpclient know issue. http://connect.microsoft.com/visualstudio/feedback/details/146711/smtp-never-sends-the-quit-command

your question similar one: properly disposing resources used smtpclient

the issue has been fixed in .net 4.0 http://msdn.microsoft.com/en-us/library/system.net.mail.smtpclient(v=vs.100).aspx , (and many other reasson) advisible update .net framework (althought know upgrading issue).

but, if want dispose smtpclient, can make class disposable yourself. don't know how goes smtpclient. http://forums.asp.net/t/383218.aspx/1 http://msdn.microsoft.com/en-us/library/fs2xkftw.aspx

as side note, advise handle catch smtpfailedrecipientsexception, not treat exceptions generic. smtpstatuscode in innerexception gives important informations.

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!
