c# - Custom app.config section with a simple list of "add" elements -

how create custom app.config section simple list of add elements?

i have found few examples (e.g. how create custom config section in app.config?) custom sections this:

<registercompanies>   <companies>     <company name="tata motors" code="tata"/>     <company name="honda motors" code="honda"/>   </companies> </registercompanies>

but how avoid collection element ("companies") looks same appsettings , connectionstrings sections? in other words, i'd like:

<registercompanies>   <add name="tata motors" code="tata"/>   <add name="honda motors" code="honda"/> </registercompanies>

full example code based on op config file:

<configuration>     <configsections>         <section name="registercompanies"                   type="my.myconfigsection, my.assembly" />     </configsections>     <registercompanies>         <add name="tata motors" code="tata"/>         <add name="honda motors" code="honda"/>     </registercompanies> </configuration>

here sample code implement custom config section collapsed collection

using system.configuration; namespace { public class myconfigsection : configurationsection {     [configurationproperty("", isrequired = true, isdefaultcollection = true)]     public myconfiginstancecollection instances {         { return (myconfiginstancecollection)this[""]; }         set { this[""] = value; }     } } public class myconfiginstancecollection : configurationelementcollection {     protected override configurationelement createnewelement() {         return new myconfiginstanceelement();     }      protected override object getelementkey(configurationelement element) {         //set whatever element property want use key         return ((myconfiginstanceelement)element).name;     } }  public class myconfiginstanceelement : configurationelement {     //make sure set iskey=true property exposed getelementkey above     [configurationproperty("name", iskey = true, isrequired = true)]     public string name {         { return (string) base["name"]; }         set { base["name"] = value; }     }      [configurationproperty("code", isrequired = true)]     public string code {         { return (string) base["code"]; }         set { base["code"] = value; }     } } }

here example of how access configuration information code.

var config = configurationmanager.getsection("registercompanies")                   myconfigsection;  console.writeline(config["tata motors"].code); foreach (var e in config.instances) {     console.writeline("name: {0}, code: {1}", e.name, e.code);  }

javascript - Enclosure Memory Copies -

function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
