c# - Serialize List<Object> that property of list item is element name in XML -


i don't know if topic correct, if not please correct. far not sure search problem maybe question has been answered before.

currently have following class (as example):

[serializable] public class sample {     public string { get; set; }     public list<parameter> parameters { get; set; } }   [serializable] public class parameter {     public string name { get; set; }     public string value { get; set; } }

this structure have serialize following xml:

<sample>    <something>1234512345112345</something>      <parameters>      <name>value</name>      <name>value</name>    </parameters>  </sample>

so xml should contain property value of attribute "name" xml-element name.

update 20.05.2015 have following xml content:

 <?xml version="1.0" encoding="utf-16" ?>   <processdata>  <id>123456</id>    <idytpe>baseplate</idytpe>    <state>fail</state>    <recipe>654321</recipe>   <processdataparameter>   <test_0>0</test_0>    <test_1>12,34</test_1>    <test_2>24,68</test_2>    <test_3>37,02</test_3>    <test_4>49,36</test_4>    <test_5>61,7</test_5>    </processdataparameter>   </processdata>

when try use following code deserialize:

 public void readxml(xmlreader reader)         {             reader.readstartelement("processdata");              this.id = reader.readelementstring("id");             this.idtype = reader.readelementstring("idytpe");             this.state = reader.readelementstring("state");             this.recipe = reader.readelementstring("recipe");              reader.readstartelement("processdataparameter");             this.processdataparameter = new list<processdataparameter>();              var subtree = reader.readsubtree();              while (subtree.read())             {                 if (subtree.nodetype == xmlnodetype.text)                 {                     var nm = subtree.localname;                     //parameters.add(new parameter { name = nm, value = subtree.value });                  }             }              reader.readendelement();          }

everything gets read out fine expect process data parameters.

it seems subtree.read() reades element out of xml content instead of elements contained in .

in while loop reader goes through following values (debuged)

  • test_0 (start tag)
  • 0 (value between tag)
  • test_0 (end tag

and out of while. seems reader sees subtree. further 0 - value gets recognized xmlnodetype.text

you implement ixmlserializable , create own custom serialization behaviour sample class. in case should work

[serializable] public class sample : ixmlserializable {     public string { get; set; }     public list<parameter> parameters { get; set; }      public xmlschema getschema()     {         return null;     }      public void readxml(xmlreader reader)     {         xmldocument doc = new xmldocument();         doc.load(reader);          = doc.selectsinglenode(@"/sample/something").firstchild.value;          var parameters = doc.selectsinglenode(@"/sample/parameters");         if (parameters.haschildnodes)         {             parameters = new list<parameter>();             foreach (xmlelement childnode in parameters.childnodes)             {                 parameters.add(new parameter {name = childnode.localname, value = childnode.firstchild.value});             }         }     }      public void writexml(xmlwriter writer)     {         writer.writeelementstring("something", this.something);         writer.writestartelement("parameters");         foreach (var parameter in parameters)         {             writer.writeelementstring(parameter.name, parameter.value);         }         writer.writeendelement();     } }

updated include readxml implementation deserialization i'm not quite sure if readxml complete can't test now, might have tweak bit parameters

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.

javascript - IE11 incompatibility with jQuery's 'readonly'? -

the code i'm running has no issues in firefox, or chrome. user typing 1 textbox, tabs next , can continue typing that. when run webpage on ie11, user tabs next textbox , can't type in. textbox has double-clicked before user can insert anything. i've googled , seems ie give problems when using older jquery (i.e. prefers 'prop' 'attr' ). in code below jquery's readonly keyword being used in way ie11 no longer recognise/accept? i assume issue readonly , removeclass('ignore') working expected. //when focus on textbox 1 $("#field1").focus(function() { //remove readonly property textbox 1 $('#field1').prop('readonly', false).removeclass('ignore'); //add readonly property other textboxes $('#field2, #field3, #field4') .prop('readonly', 'readonly').addclass('ignore').val(''); }); i'm using jquery 2.1.3 ...
