老实说,在以前没写个自定义配置节点之前,我都是写到一个很常用的节点里面,就是appSettings里add,然后再对各个节点的value值进行字符串分割操作,根据各种分割字符嵌套循环处理,后来看到一些常用的框架都会加个configSections,然后百度后发现可以自己写配置文件节点,然后就在项目中定义自己的节点
其实,上面说的都是废话,现在项目中要用WCF服务,用传统的WCF配置工具或者手写的会有一堆配置,所以我稍作了简化,看下面的
<?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <section name="test" type="TestService.Common.Config.TestServiceSection, TestService.Common" /> </configSections> <test> <add name="TestService" service="TestService.ApplicationService.TestService, TestService.ApplicationService" contract="TestService.Contract.ITestService, TestService.Contract" uri="net.tcp://localhost:10001/TestService" /> <add name="FileService" service="TestService.ApplicationService.FileService, TestService.ApplicationService" contract="TestService.Contract.IFileService, TestService.Contract" uri="net.tcp://localhost:10001/FileService" /> <add name="MessageService" service="TestService.ApplicationService.MessageService, TestService.ApplicationService" contract="TestService.Contract.IMessageService, TestService.Contract" uri="net.tcp://localhost:10001/MessageService" /> </test> </configuration>
上面的test就是我定义的节点,子节点是各个WCF的配置,看下TestServiceSection里面是个什么鬼
using System; using System.Collections; using System.Collections.Generic; using System.Configuration; using System.Linq; using System.Text; namespace TestService.Common.Config { public sealed class TestServiceSection : ConfigurationSection { private static readonly ConfigurationProperty s_property = new ConfigurationProperty(string.Empty, typeof(TheKeyValueCollection), null, ConfigurationPropertyOptions.IsDefaultCollection); [ConfigurationProperty("", Options = ConfigurationPropertyOptions.IsDefaultCollection)] public TheKeyValueCollection KeyValues { get { return (TheKeyValueCollection)base[s_property]; } } public static TestServiceSection GetConfig() { TestServiceSection configSection= (TestServiceSection)ConfigurationManager.GetSection("test"); if (configSection == null) throw new ConfigurationErrorsException("Section test is not found."); return configSection; } public static TestServiceSection GetConfig(string configPath) { var fileMap = new ExeConfigurationFileMap() { ExeConfigFilename = configPath }; var config = ConfigurationManager.OpenMappedExeConfiguration(fileMap, ConfigurationUserLevel.None); TestServiceSection configSection = (TestServiceSection)config.GetSection("test"); if (configSection == null) throw new ConfigurationErrorsException("Section test is not found."); return configSection; } } [ConfigurationCollection(typeof(TheKeyValue))] public class TheKeyValueCollection : ConfigurationElementCollection // 自定义一个集合 { new TheKeyValue this[string name] { get { return (TheKeyValue)base.BaseGet(name); } } // 下面二个方法中抽象类中必须要实现的。 protected override ConfigurationElement CreateNewElement() { return new TheKeyValue(); } protected override object GetElementKey(ConfigurationElement element) { return ((TheKeyValue)element).Name; } } public class TheKeyValue : ConfigurationElement { [ConfigurationProperty("name", IsRequired = true)] public string Name { get { return this["name"].ToString(); } set { this["name"] = value; } } [ConfigurationProperty("uri", IsRequired = true)] public string Uri { get { return this["uri"].ToString(); } set { this["uri"] = value; } } [ConfigurationProperty("service", IsRequired = true)] public string Service { get { return this["service"].ToString(); } set { this["service"] = value; } } [ConfigurationProperty("contract", IsRequired = true)] public string Contract { get { return this["contract"].ToString(); } set { this["contract"] = value; } } } }
有了上面的一块代码,编译是冒得问题的,那么问题来了,怎么取自定义配置节点里的东西呢?
look
TestServiceSection services = TestServiceSection.GetConfig(); foreach (TheKeyValue item in services.KeyValues) { var i = item.ElementInformation; }
循环里面的就是配置节点里的信息,可以卡个断点看看,是不是so easy!好了,今天就写到这儿.
