update web.config through c# code

I am trying to update some configuration settings at run time via my c# code. This is my section of the web.config

<appSettings>
    <add key="webpages:Version" value="3.0.0.0" />
    <add key="webpages:Enabled" value="false" />
    <add key="ClientValidationEnabled" value="true" />
    <add key="UnobtrusiveJavaScriptEnabled" value="true" />
    <add key="URL" value="google.com"/>
  <add key="Domain" value="d"/>
  <add key="Project" value="p"/>
  </appSettings>

And this is the code that I am using :

Configuration config = WebConfigurationManager.OpenWebConfiguration("~");
System.Configuration.ConfigurationManager.AppSettings.Remove("URL");
System.Configuration.ConfigurationManager.AppSettings.Add("URL","www.stackoverflow.com");
config.Save();

However , it is giving the error that my config file is read-only. I am using Visual Studio 2013. How should I fix this?

Will you please try this ?

protected void EditConfigButton(object sender, EventArgs e)
{
   Configuration objConfig = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~");
   AppSettingsSection objAppsettings = (AppSettingsSection)objConfig.GetSection("appSettings");
   //Edit
   if (objAppsettings != null)
   {
      objAppsettings.Settings["test"].Value = "newvalueFromCode";
      objConfig.Save();
   }
}
