in model have,

namespace mypro.web.models.mypro {     using system;     using system.collections.generic;     using system.configuration;     using system.linq;     using system.net;     using system.net.http;     using system.web.http;     using mypro.model;      public class mypromodel     {          public mypromodel(dictionary<string, dynamic> myprodata)         {             this.myprodata = myprodata;         }          public dictionary<string, dynamic> myprodata { get; private set; }     } }

and in cshtml page have 

@model mypro.web.models.mypro.mypromodel   <div class="content">      <h1 class="sectionheading">contact us</h1>     @foreach (var item in model.myprodata)     {     <div class="contentsection">         <h2>tables</h2>         <div class="innercontentsection">             <table class="basetable">                 <thead><tr><th>column1</th><th>colum2</th></tr></thead>                 <tbody>                         <tr><td>@model.myprodata</td><td>@model.myprodata["general"].</td></tr>                         <tr><td>@model.myprodata</td><td>@model.myprodata["other"]</td></tr>                 </tbody>             </table>         </div>     </div>     } </div>

my question how column1 show strings general , other , column2 display somevalue1 , othervalue values appsettings, practice i'm trying accomplish or there better way. have tried other methods stack using lists, hashtables etc. there simple way grab or extract data key , value.

you want use allkeys attribute of appsettings. example:

    public actionresult mypro()     {         dictionary<string, dynamic> myprodata = new dictionary<string, dynamic>();         configurationmanager.appsettings.allkeys.tolist().foreach         (             settingskey =>             myprodata.add(settingskey, configurationmanager.appsettings[settingskey]);         );         var mypromodel = new mypromodel(myprodata);          return view(mypromodel);     }

as mentioned below, if want subset of keys output...
first add new item config:

<add key ="configitemstomonitor" value="general,other"/>

then use key generate list output:

    public actionresult mypro()     {         dictionary<string, dynamic> myprodata = new dictionary<string, dynamic>();         configurationmanager.appsettings["configitemstomonitor"].split(',').tolist().foreach         (             settingskey =>             myprodata.add(settingskey, configurationmanager.appsettings[settingskey]);         );         var mypromodel = new mypromodel(myprodata);          return view(mypromodel);     }

you decide monitor value of configitemstomonitor - add comma separated list of values. make sure exclude spaces.
