配置管理应用程序块（Configuration Application Block）

备忘：

app.config

<configuration>
    <configSections>
        <section name="fileSystemStorageProvider" type="ConfigurationDemo.FileSystemStorageSettings, ConfigurationDemo" />

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:

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();
