读配置文件：

1，

类：FileSystemStorageSettings

 

using  System.Configuration;

namespace  ConfigurationDemo
{
     public   class  FileSystemStorageSettings : ConfigurationSection
    {
        [ConfigurationProperty( " Root " )]
         public   string  Root
        {
             get  {  return  ( string ) this [ " Root " ]; }
             set  
            {
                 this [ " Root " ]  =  value;
            }
        }

        [ConfigurationProperty( " FolderPattern " )]
         public   string  FolderPattern
        {
             get  {  return  ( string ) this [ " FolderPattern " ]; }
             set
            {
                 this [ " FolderPattern " ]  =  value;
            }
        }

        [ConfigurationProperty( " ApDocConverterTimeout " )]
         public   short  ApDocConverterTimeout
        {
             get  {  return  ( short ) this [ " ApDocConverterTimeout " ]; }
             set
            {
                 this [ " ApDocConverterTimeout " ]  =  value;
            }
        }
    }
}

 

FileSystemStorageSettings setting  =  ConfigurationManager.GetSection( " fileSystemStorageProvider " )  as  FileSystemStorageSettings;
             if (setting  !=   null )
            {
                 // ...
            }

2，

类:

 

FileSystemStorageSettingsOther

using  System;
using  System.Configuration;
using  System.Xml;

namespace  ConfigurationDemo
{
     public   class  FileSystemStorageSettingsOther
    {
         private   readonly   string  root;
         private   readonly   string  folderPattern;
         private   readonly   short  apDocConverterTimeout;

         public  FileSystemStorageSettingsOther( string  root,  string  folderPattern,  string  apDocConverterTimeout)
        {
             this .root  =  root;
             this .folderPattern  =  folderPattern;

             if  ( ! short .TryParse(apDocConverterTimeout,  out   this .apDocConverterTimeout))
                 this .apDocConverterTimeout  =   30 ;
        }

         public   string  Root
        {
             get  { return  root;}
        }

         public   string  FolderPattern
        {
             get  { return  folderPattern;}
        }

         public   short  ApDocConverterTimeout
        {
             get  {  return  apDocConverterTimeout; }
        }
    }

     public   class  FileSystemStorageProviderSectionHandler : IConfigurationSectionHandler
    {
         public   object  Create( object  parent,  object  configContext, XmlNode section)
        {
             try
            {
                XmlElement rootNode  =  (XmlElement)section.SelectSingleNode( " param[@name='Root'] " );
                 string  root  =  rootNode.Attributes[ " value " ].InnerText;

                XmlElement folderPatternNode  =  (XmlElement)section.SelectSingleNode( " param[@name='FolderPattern'] " );
                 string  folderPattern  =  folderPatternNode.Attributes[ " value " ].InnerText;

                XmlElement apDocConverterTimeoutNode  =  (XmlElement)section.SelectSingleNode( " param[@name='apDocConverterTimeout'] " );
                 string  apDocConverterTimeout;
                 if  (apDocConverterTimeoutNode  ==   null )
                    apDocConverterTimeout  =   null ;
                 else
                    apDocConverterTimeout  =  apDocConverterTimeoutNode.Attributes[ " value " ].InnerText;

                 return   new  FileSystemStorageSettingsOther(root, folderPattern, apDocConverterTimeout);
            }
             catch  (Exception ex)
            {
                 throw  ex;
            }
        }
    }
}

 

调用：

FileSystemStorageSettingsOther setting  =  ConfigurationManager.GetSection( " fileSystemStorageProviderOther " )  as  FileSystemStorageSettingsOther;

             if (setting  !=   null )
            {
                 // ...
            }

 

写入配置文件：

 

1,

　　　　　　　　  Configuration config  =  ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
                config.Sections.Remove( " EditorSettings " );
                config.Sections.Add( " EditorSettings " , configData);                
                config.Save();

 

2,  ExeConfigurationFileMap fileMap = new ExeConfigurationFileMap();
    fileMap.ExeConfigFilename = @"E:\EntLib3Src\Quick Starts\Configuration-Migration\CS\ConfigurationMigrationQuickStart\app.config";

    Configuration config = ConfigurationManager.OpenMappedExeConfiguration(fileMap, ConfigurationUserLevel.None);
    config.Sections.Remove("EditorSettings");
    config.Sections.Add("EditorSettings", configData);
    config.Save();
