.Net里面，ConfigurationManager默认读取的是Web.config或者App.config但是，什么都放在这两个文件里面，感觉太多了，也不好管理配置。于是参考了下别人的资料，自己写了一个例子，例子实现的的是E:\App.config的文件，文件格式如下
     
       
          
       
  
        
          
         
        
     要实现这样的功能，就要实现自己的ConfigurationSection，ConfigurationElementCollection，ConfigurationElement 1.ConfigurationSectionpublic class BooksSection : ConfigurationSection    {        [ConfigurationProperty("books", IsRequired = true)]        public string Category        {            get            {                return (string)base["Category"];            }            set            {                base["Category"] = value;            }        }        [ConfigurationProperty("", IsDefaultCollection = true)]        public BookElementCollection Books        {            get            {                return (BookElementCollection)base[""];            }        }    }2.ConfigurationElementCollection    public class BookElementCollection : ConfigurationElementCollection    {        protected override ConfigurationElement CreateNewElement()        {            return new BookElement();        }        protected override object GetElementKey(ConfigurationElement element)        {            return ((BookElement)element).Name;        }        public override ConfigurationElementCollectionType CollectionType        {            get            {                return ConfigurationElementCollectionType.BasicMap;            }        }        protected override string ElementName        {            get            {                return "book";            }        }        public BookElement this[int index]        {            get            {                return (BookElement)BaseGet(index);            }            set            {                if (BaseGet(index) != null)                {                    BaseRemoveAt(index);                }                BaseAdd(index, value);            }        }    }3.ConfigurationElement    public class BookElement : ConfigurationElement    {        [ConfigurationProperty("name", IsRequired = true)]        public string Name        {            get            {                return (string)base["name"];            }            set            {                base["name"] = value;            }        }        [ConfigurationProperty("author", IsRequired = true)]        public double Author        {            get            {                return (double)base["author"];            }            set            {                base["author"] = value;            }        }    }4.0Config文件
