在web.config或者app.config中如何增加自定义配置节

这篇文章主要介绍在web.config或者app.config中如何增加自定义配置节，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！

简单键值对

web.config

users.config

c#

NameValueCollection users = System.Configuration.ConfigurationManager.GetSection("users") as NameValueCollection;            Response.Write(users.Keys[0]+"
"+users.Keys[1]);

复杂类型

web.config

roles.config

RolesCofig.cs

using System;using System.Collections.Generic;using System.Linq;using System.Web;namespace EBuy.Chapter3.NTier.WebUI{    public class RolesConfig : System.Configuration.IConfigurationSectionHandler    {        public object Create(object parent, object configContext, System.Xml.XmlNode section)        {            return section;        }    }}

c#

XmlNode roles= System.Configuration.ConfigurationManager.GetSection("roles") as XmlNode;           Response.Write(roles.ChildNodes [0].Attributes["username"].InnerText);

还可以将配置节定义为一个实体

using System;using System.Collections.Generic;using System.Linq;using System.Web;namespace EBuy.Chapter3.NTier.WebUI{    public class RolesConfig : System.Configuration.IConfigurationSectionHandler    {        public object Create(object parent, object configContext, System.Xml.XmlNode section)        {            var list=new List();            for(int i=0;i
var roles = System.Configuration.ConfigurationManager.GetSection("roles") as List;          Response.Write(roles.First ().Username);
