configsections configuration of C # configuration files

For small projects, configuration information can be configured through appsettings, and if the configuration information is too much, appsettings seems a bit messy, and when the developer calls, is not friendly, the node name is easy to write wrong, at this time, we have several solutions

1 Develop a configuration information persistence class for managing configuration information and providing object-oriented support2 using the. NET configsections, the configuration information is chunked managed, and the entity classes are provided, making it easy for developers to use it

This article is mainly about the second scenario, which consists of the entity class, the entity class factory and the configuration file three parts, see the code:

Entity class Design:

1 namespaceConfiger2 {3     /// <summary>4     ///Site information Configuration node5     /// </summary>6      Public classwebconfigsection:configurationsection7     {8         /// <summary>9         ///Site nameTen         /// </summary> One[ConfigurationProperty ("WebName", DefaultValue ="", isrequired =true, IsKey =false)] A          Public stringWebName -         { -  the             Get{return(string) This["WebName"]; } -             Set{ This["WebName"] =value;} -         } -         /// <summary> +         ///website domain name -         /// </summary> +[ConfigurationProperty ("DoMain", DefaultValue ="", isrequired =true, IsKey =false)] A          Public stringDoMain at         { -  -             Get{return(string) This["DoMain"]; } -             Set{ This["DoMain"] =value;} -         } -  in     } -}

Entity factory class design, mainly used to produce entity configuration information

1 namespaceConfiger2 {3     /// <summary>4     ///Site configuration Information Factory5     /// </summary>6      Public classWebconfigmanager7     {8         /// <summary>9         ///Configuration Information EntityTen         /// </summary> One          Public Static ReadOnlyWebconfigsection Instance =GetSection (); A  -         Private Staticwebconfigsection GetSection () -         { thewebconfigsection config = configurationmanager.getsection ("webconfigsection") aswebconfigsection; -             if(config = =NULL) -                 Throw Newconfigurationerrorsexception (); -             returnconfig; +         } -     } +}

And finally, the. config file, which has configsections and the specified sections block, it is important to note that the configsections must be in the first position of the configuration

1 <?XML version= "1.0" encoding= "Utf-8"?>2 <Configuration>3   <configsections>4     < Sectionname= "Webconfigsection"type= "configer.webconfigsection, test"/>5   </configsections>6   <connectionStrings>7     <Addname= "Backgroundentities"connectionString= "metadata=res://*/model1.csdl|res://*/model1.ssdl|res://*/model1.msl;provider=system.data.sqlclient; Provider connection String=&quot;data source=.\sqlexpress;initial catalog=background;integrated Security=True; multipleactiveresultsets=true&quot; "ProviderName= "System.Data.EntityClient" />8   </connectionStrings>9 Ten   <webconfigsectionWebName= "Occupy Site"DoMain= "Www.zhanzhan.com"  /> One   <appSettings> A     <AddKey= "Site"value= "Www.zzl.com"/> -  -   </appSettings> the </Configuration>

After the implementation of the above three steps, we can call it, hehe

1 Static void Main (string[] args)2   {3      Console.WriteLine ( system.configuration.configurationmanager.appsettings["site"]); 4      Console.WriteLine (WebConfigManager.Instance.DoMain); 5      Console.WriteLine (WebConfigManager.Instance.WebName); 6    }
