NET Web. config Single solution (additional configuration introduction)

A recent project needs to write a lot of configuration items and find that writing in a single Web. config can be messy and difficult to find

So the search was settled, and it was recorded.

First, Webconfig provides a way to introduce other Config

<connectionstrings configsource= "Configs\database.config"/>

This is the configuration of the connection string you can have in database. Config contains a lot of link strings in case you call

Database The contents of config are as follows:

<? XML version= "1.0" encoding= "Utf-8" ?> < connectionStrings >  <  name= "Sdbcontext"  connectionString= "Server=.;i Nitial catalog=self; User Id=sa; Password=password "  providerName=" System.Data.SqlClient "/></  connectionStrings>

<appsettings configsource= "Configs\system.config"/>

This is the way the key-value pairs are stored in the following code:

<?XML version= "1.0" encoding= "Utf-8"?><appSettings>  <!--================== 1: Development of system-related configuration ================== -  <!--Login Provider mode: Session, Cookie -  <AddKey= "Loginprovider"value= "Cookie" />  <!--Enable System log -  <AddKey= "Islog"value= "true" />  <!--Database over time -  <AddKey= "CommandTimeout"value= " the" />  <!--Enable IP Filtering -  <AddKey= "Isipfilter"value= "false" />  <!--================== 2: System software parameter configuration ================== -  <!--Contact Us -  <AddKey= "Contact"value= "TE software (Mobility)" />  <!--Software name -  <AddKey= "Softname"value= "Sub self" />  <!--software version -  <AddKey= "Version"value= "1.0" />  <!--set to apply path -  <AddKey= "AppName"value="" />  <!--set to apply path -  <AddKey= "Sqlgetbomlist"value="" /></appSettings>

Above two do not need special configuration, put in the configuration inside the configsections below so that you can

Second, the following introduction of the Custom configuration section

<configsections>                                                                                                                                < Sectionname= "Users"type= "System.Configuration.NameValueSectionHandler"/>                                                                                                                                                                                                                                                             </configsections> <UsersConfigSource= "Users.config"></Users>

Note that one of the configsections is a statement of how this is organized

The contents of Users.config are as follows:

<Users>  <AddKey= "Beijing"value= "123"></Add>  <AddKey= "Tianjin"value= "123"></Add></Users>

How to get the configuration:

NameValueCollection users = System.Configuration.ConfigurationManager.GetSection ("users") as NameValueCollection;            Response.Write (Users. keys[0]+ "</br>" +users. KEYS[1]);

Three, Complex type:

The declaration of a complex type is different.

<configsections>                                                                          < Sectionname= "Roles"type= "EBuy.Chapter3.NTier.WebUI.RolesConfig, EBuy.Chapter3.NTier.WebUI"/>                                                                          </configsections><RolesConfigSource= "Roles.config">  </Roles>

The contents are as follows

<Roles>  <Addusername= "Beijing"Password= "123"></Add>  <Addusername= "Tianjin"Password= "123"></Add></Roles>

How to obtain:

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;}}    }

　　

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

Can also be configured as an entity

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<role> ();            for (int i=0;i<section. childnodes.count;i++)            {                list. ADD (New Role () {                    Username =section. Childnodes[i]. attributes["username"]. InnerText,                    Password =section. Childnodes[i]. attributes["Password"]. InnerText});            }            return list;        }    }    public class Role    {public        string Username {get; set;}        public string Password{get;set;}}    }

　　

var roles = System.Configuration.ConfigurationManager.GetSection ("Roles") as List<ebuy.chapter3.ntier.webui.role >;          Response.Write (Roles. First (). Username);
