c# - Deserializing xml to list object returning null -


i'm trying deserialize xml data using xmlreader list object getting null call. here sample of xml data...

<exceptionlog>     <exceptionlogdata messagecount="1" sourcedatetime="2016-02-08t09:32:41.713" minsourcedatetime="2016-02-08t09:32:41.713" dataid="610029" maxexceptionlogid="610029" messagetext="invalid_session_id: invalid session id found in sessionheader: illegal session. session not found, missing session hash: hx7k7lonetilw5rfgt432g==&#xa;this expected, can happen if session has expired , swept away, or if user logs out, or if trying hack in. " machinename="vertexdportsql1" appdomainname="vtms.windows.salesforceservicingagent.exe" processname="vtms.windows.salesforceservicingagent" />     <exceptionlogdata messagecount="1" sourcedatetime="2016-02-08t09:22:39.340" minsourcedatetime="2016-02-08t09:22:39.340" dataid="610028" maxexceptionlogid="610028" messagetext="invalid_session_id: invalid session id found in sessionheader: illegal session. session not found, missing session hash: rtztrlk2f99ivttloz31tg==&#xa;this expected, can happen if session has expired , swept away, or if user logs out, or if trying hack in. " machinename="vertexdportsql1" appdomainname="vtms.windows.salesforceservicingagent.exe" processname="vtms.windows.salesforceservicingagent" /> </exceptionlog>

this object class code trying create...

public class exceptionlog {     public exceptionlog() {         exceptionlogdata = new list<exceptionlogexceptionlogdata>();     }      public list<exceptionlogexceptionlogdata> exceptionlogdata { get; set; } }  public class exceptionlogexceptionlogdata {     private datetime _sourcedatetimefield;      private datetime _minsourcedatetimefield;      private uint dataidfield;      private uint _maxexceptionlogidfield;      private string _messagetextfield;      private string _machinenamefield;      private string _appdomainnamefield;      private string _processnamefield;      public byte messagecount { get; set; }      public datetime sourcedatetime {         {             return _sourcedatetimefield;         }         set {             _sourcedatetimefield = value;         }     }      public datetime minsourcedatetime {         {             return _minsourcedatetimefield;         }         set {             _minsourcedatetimefield = value;         }     }      public uint dataid {         {             return dataidfield;         }         set {             dataidfield = value;         }     }      public uint maxexceptionlogid {         {             return _maxexceptionlogidfield;         }         set {             _maxexceptionlogidfield = value;         }     }      public string messagetext {         {             return _messagetextfield;         }         set {             _messagetextfield = value;         }     }      public string machinename {         {             return _machinenamefield;         }         set {             _machinenamefield = value;         }     }      public string appdomainname {         {             return _appdomainnamefield;         }         set {             _appdomainnamefield = value;         }     }      public string processname {         {             return _processnamefield;         }         set {             _processnamefield = value;         }     } }

and here how trying deserialize data...

        using (var datareader = sqlcommand.executexmlreader())         {             var serializer = new xmlserializer(typeof(exceptionlog));              var returndatalist = serializer.deserialize(datareader) list<exceptionlogexceptionlogdata>;             return returndatalist;         }

what have missed or doing wrong?

i have approach can use until figure out , old fashioned way of creating object list , programmatically populating objects on fly - not graceful time being works.

xmlserializer defined of type exceptionlog you're casting result list

var serializer = new xmlserializer(typeof(exceptionlog)); var returndatalist = serializer.deserialize(datareader) list<exceptionlogexceptionlogdata>;

the casting should type of serializer:

var returndatalist = serializer.deserialize(datareader) exceptionlog;

i didn't check elements should mark exceptionlogdata xmlelement attribute. 

[xmlelement] public list<exceptionlogexceptionlogdata> exceptionlogdata { get; set; }

there might issues other properties should address problem in question

java - pagination of xlsx file to XSSFworkbook using apache POI -

right in code, reading xlsx file, xssfworkbook, , writing database. but, when size of xlsx file increases, causes outofmemory error. can not increase server size, or divide xlsx file pieces. tried loading workbook using file (instead of inputstream), didn't either. i looking way read 10k rows @ time (instead of entire file @ once) , iteratively write workbook , database. is there way apache poi? poi contains called "eventmodel" designed purpose. it's mentioned in faq : the ss eventmodel package api reading excel files without loading whole spreadsheet memory. require more knowledge on part of user, reduces memory consumption more tenfold. based on awt event model in combination sax. if need read-only access, best way it. however, may want double check first if issue somewhere else. check out this item : i think poi using memory! can do? 1 comes quite lot, reason isn't might think. so, first thing check - what's source of prob...

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac

apache - How do I stop my index.php being run twice for every user -

we've got webapp initial html served using apache , php. i noticed index.php being run twice every request. seems caused / effected rewrite rules in our .htaccess - rewritecond %{http_host} ^(www\.|hotels\.)ourdomain\.com$ [nc,or] rewritecond %{server_name} ^(www\.|hotels\.)ourdomain\.com$ [nc] rewriterule (.*) http://ourdomain.com/$1 [r=301] rewriterule ^hotels/([^/]+)/?\??(.*)$ ?d=$1&$2 [qsa] the final rule moving parameter url path query string. i.e. http://ourdomain.com/hotels/vegas?someparam=1 becomes http://ourdomain.com?d=vegas&someparam=1 if go directly query string version index.php run once. if use url redirected, index.php run twice (i'm checking adding error_log('end of index.php') file). so example going http://ourdomain.com/hotels/paris hits file twice http://ourdomain.com?d=paris hits once. i've seen this question , had @ blog mentioned , , can't find empty string url's (i've tried using yslow process). ...
