title: I need to set the value of <add key="FileSystemResourcePath" value="abc.config"/> at runtime in code behind
body: <p>My Web.Config looks something like below:</p>
  
  <pre><code>&lt;?xml version="1.0"?&gt;
  &lt;configuration&gt;
    &lt;configSections&gt;
      &lt;sectionGroup name="EAFramework"&gt;
        &lt;section name="ConfigurationFile" type="System.Configuration.NameValueSectionHandler, System, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/&gt;
      &lt;/sectionGroup&gt;
    &lt;/configSections&gt;
    &lt;EAFramework&gt;
      &lt;ConfigurationFile&gt;
        &lt;add key="FileSystemResourcePath" value="abc.config"/&gt;
      &lt;/ConfigurationFile&gt;
    &lt;/EAFramework&gt;
    &lt;appSettings&gt;
      &lt;add key="RecordUpdateNotifyString" value="Set records updated with date printed "/&gt;
      &lt;add key="RecordUpdateFailString" value="Failed to Print Records."/&gt;
    &lt;/appSettings&gt;
  .
  .
  .
  </code></pre>
  
  <p>for key="FileSystemResourcePath" i need to set value at run time to default directory from where application is running.</p>
  
  <p>For eg : Say my application runs from C:/MyFolder, value for above key should hold C:/MyFolder/abc.config.</p>
