经常在使用APP.CONFIG 或WEB.CONFIG
时，发现系统中的配置无法满足自己的需求。这时就需要自定义的配置文件处理：
现需要在配置文件中定义可增加删除任务的功能。可根据需要增加一个或删除任务。
定义配置节点
////// MRP自定义配置类 /// public class MRPSection : ConfigurationSection { ////// Gets the tasks. /// ///The tasks. [ConfigurationProperty("", IsDefaultCollection = true)] public TaskCollectionElement Tasks { get { return (TaskCollectionElement)this[""]; } } }
配置集合
////// 任务集合 /// public class TaskCollectionElement : ConfigurationElementCollection { protected override ConfigurationElement CreateNewElement() { return new TaskElement(); } protected override object GetElementKey(ConfigurationElement element) { return ((TaskElement)element).CompanyID; } public override ConfigurationElementCollectionType CollectionType { get { return ConfigurationElementCollectionType.BasicMap; } } protected override string ElementName { get { return "Task"; } } public TaskElement this[int index] { get { return (TaskElement)BaseGet(index); } set { if (BaseGet(index) != null) { BaseRemoveAt(index); } BaseAdd(index, value); } } }
定义任务类
public class TaskElement : ConfigurationElement { [ConfigurationProperty("CompanyID", IsRequired = true)] public string CompanyID { get { return (string)base["CompanyID"]; } } [ConfigurationProperty("DatabaseName", IsRequired = true)] //[RegexStringValidator(可以在这里用正则验证配置文件中的值是否正确)] public string DatabaseName { get { return this["DatabaseName"] as string; } } [ConfigurationProperty("Level", IsRequired = true)] public string Level { get { return this["Level"] as string; } } [ConfigurationProperty("AppIP", IsRequired = true)] public string AppIP { get { return this["AppIP"].ToString(); } } [ConfigurationProperty("AppName", IsRequired = true)] public string AppName { get { return this["AppName"].ToString(); } } } 配置文件如下
如何访问：
MRPSection mrpsetting = (MRPSection)ConfigurationManager.GetSection("MRPSetting"); foreach (TaskElement task in mrpsetting.Tasks) { Console.WriteLine(task.CompanyID); } ----------------------------------------------------------------------------------------------------------------------------------------------------------
若自定义的节点不需要集合类,则只需要如下定义即可
public class TaskSection : ConfigurationSection { [ConfigurationProperty("CompanyID", IsRequired = true)] public string CompanyID { get { return (string)base["CompanyID"]; } } [ConfigurationProperty("DatabaseName", IsRequired = true)] //[RegexStringValidator(可以在这里用正则验证配置文件中的值是否正确)] public string DatabaseName { get { return this["DatabaseName"] as string; } } [ConfigurationProperty("Level", IsRequired = true)] public string Level { get { return this["Level"] as string; } } [ConfigurationProperty("AppIP", IsRequired = true)] public string AppIP { get { return this["AppIP"].ToString(); } } [ConfigurationProperty("AppName", IsRequired = true)] public string AppName { get { return this["AppName"].ToString(); } } } 此Task节点不可以重复，否则系统运行通不过。
