自定义app.config Config节处理程序 (1个答案)
6年前关闭。
我想在app.config文件中添加一个自定义配置部分。有没有办法做到这一点,以及如何在程序中访问这些设置。以下是我要添加到我的配置部分app.config:
app.config
<RegisterCompanies> <Companies> <Company name="Tata Motors" code="Tata"/> <Company name="Honda Motors" code="Honda"/> </Companies> </RegisterCompanies>
导入名称空间:
using System.Configuration;
创建ConfigurationElement公司:
public class Company : ConfigurationElement { [ConfigurationProperty("name", IsRequired = true)] public string Name { get { return this["name"] as string; } } [ConfigurationProperty("code", IsRequired = true)] public string Code { get { return this["code"] as string; } } }
ConfigurationElementCollection:
public class Companies : ConfigurationElementCollection { public Company this[int index] { get { return base.BaseGet(index) as Company ; } set { if (base.BaseGet(index) != null) { base.BaseRemoveAt(index); } this.BaseAdd(index, value); } } public new Company this[string responseString] { get { return (Company) BaseGet(responseString); } set { if(BaseGet(responseString) != null) { BaseRemoveAt(BaseIndexOf(BaseGet(responseString))); } BaseAdd(value); } } protected override System.Configuration.ConfigurationElement CreateNewElement() { return new Company(); } protected override object GetElementKey(System.Configuration.ConfigurationElement element) { return ((Company)element).Name; } }
和ConfigurationSection:
public class RegisterCompaniesConfig : ConfigurationSection { public static RegisterCompaniesConfig GetConfig() { return (RegisterCompaniesConfig)System.Configuration.ConfigurationManager.GetSection("RegisterCompanies") ?? new RegisterCompaniesConfig(); } [System.Configuration.ConfigurationProperty("Companies")] [ConfigurationCollection(typeof(Companies), AddItemName = "Company")] public Companies Companies { get { object o = this["Companies"]; return o as Companies ; } } }
并且您还必须在web.config(app.config)中注册新的配置部分:
<configuration> <configSections> <section name="Companies" type="blablabla.RegisterCompaniesConfig" ..>
然后你用
var config = RegisterCompaniesConfig.GetConfig(); foreach(var item in config.Companies) { do something .. }
