前言:在添加获取配置文件自定义section 特性的数据时,遇到了问题并把它记录下来:
1. 类型“xxxxx.xxxx.sectionName”不从“System.Configuration.IConfigurationSectionHandler”继承。
这个问题应该算是一个常见的错误问题了。
解决办法:
1. 添加section标签,name为自定义标签名称,type为:类型的命名空间 + 类型,程序集名称
在配置节点下添加
<configSections><section name="RedisConfig" type="Redis.Study.Config.RedisConfigInfo,Redis.Study"/>
2.RedisConfig为自定义标签,他的数据集为(ConfigurationSection)
<RedisConfig WriteServerList="127.0.0.1:6379" ReadServerList="127.0.0.1:6379" MaxWritePoolSize="60"MaxReadPoolSize="60" AutoStart="true" LocalCacheTime="180" RecordeLog="false"></RedisConfig></configSections>
3.创建自定义标签的获取类,注意这里类的继承为数据集ConfigurationSection
这里需要对类的属性和标签属性使用:ConfigurationProperty(“标签属性”) 进行对应
public class RedisConfigInfo:ConfigurationSection{#region Property[ConfigurationProperty("WriteServerList")]public string WriteServerList {get {return (string)this["WriteServerList"]; }set {this["WriteServerList"] = value; }}[ConfigurationProperty("ReadServerList")]public string ReadServerList{get {return (string)this["ReadServerList"]; }set {this["ReadServerList"] = value; }}[ConfigurationProperty("MaxReadPoolSize")]public int MaxReadPoolSize{get {return (int)this["MaxReadPoolSize"]; }set {this["MaxReadPoolSize"] = value; }}[ConfigurationProperty("MaxWritePoolSize")]public int MaxWritePoolSize{get {return (int)this["MaxWritePoolSize"]; }set {this["MaxWritePoolSize"] = value; }}[ConfigurationProperty("AutoStart")]public bool AutoStart{get {return (bool)this["AutoStart"]; }set {this["AutoStart"] = value; }}[ConfigurationProperty("RecordeLog")]public bool RecordeLog{get {return (bool)this["RecordeLog"]; }set {this["RecordeLog"] = value; }}[ConfigurationProperty("LocalCacheTime")]public int LocalCacheTime{get {return (int)this["LocalCacheTime"]; }set {this["LocalCacheTime"] = value; }}#endregion}
4.在此类中添加获取方法对配置文件Section进行获取
返回的 section 含有所有section对应标签值
#region 获取配置方法public static RedisConfigInfo GetConfig() {RedisConfigInfo section = (RedisConfigInfo)ConfigurationManager.GetSection("RedisConfig");return section;}public static RedisConfigInfo GetConfig(string sectionName) {RedisConfigInfo section = (RedisConfigInfo)ConfigurationManager.GetSection(sectionName);if (section == null) {throw new ConfigurationErrorsException("Section " + sectionName + " is not found");}return section;}#endregion
5.在过程中,主要遇到的问题是 继承问题与标签属性的对应。 当然还有很多更多细致的内容。后续在最一个补充吧
