.Net MVC网站中配置文件的读写

三、配置节类 

类中定义私有属性KeyValues。进行读写配置节集合，然后定义一系列的需要的配置属性，操作就是对KeyValues的元素读写。 

using System.Configuration;

namespace Ninesky.Models.Config
{
 /// <summary>
 /// 上传设置配置节
 /// <remarks>

  /// </summary>
  [ConfigurationProperty("", Options = ConfigurationPropertyOptions.IsDefaultCollection)]
  private KeyValueElementCollection KeyValues
  {
   get { return (KeyValueElementCollection)base[_property]; }
   set { base[_property] = value; }
  }
  /// <summary>
  /// 最大大小

  public int MaxSize
  {
   get
   {
