自定义app.config配置节处理程序 [英] Custom app.config Config Section Handler

问题描述

如果我使用像这样的app.config，那么通过继承System.Configuration.Section的类来获取页面列表的正确方法是什么？

 <？xml version =1.0encoding =utf-8？> 
< configuration> 
 
< configSections> 
< section name =XrbSettingstype =Xrb.UI.XrbSettings，Xrb.UI/> 
< / configSections> 
 
< XrbSettings> 
< pages> 
< add title =Googleurl =http://www.google.com/> 
< add title =Yahoourl =http://www.yahoo.com/> 
< / pages> 
< / XrbSettings> 
 
< / configuration> 
  

解决方案

首先在类中添加一个属性，

  [ConfigurationProperty（pages，IsDefaultCollection = false）] 
 [ConfigurationCollection（typeof（PageCollection），AddItemName =add）] 
 public PageCollection页面{
 get {
 return（PageCollection）this [pages]; 
} 
} 
  

然后你需要创建一个PageCollection类。我看到的所有例子都是相同的，所以只需复制 this one ，并将NamedService重命名为Page。

最后添加一个扩展ObjectConfigurationElement的类：

public class PageElement：ObjectConfigurationElement {
[ConfigurationProperty（title，IsRequired = true）]
public string标题{
get {
return（string）this [title];
}
set {
this [title] = value;
}
}

[ConfigurationProperty（url，IsRequired = true）]
public string Url {
get {
return string）this [url];
}
set {
this [url] = value;
}
}
}


示例实现：

• 示例配置


• 集合和元素类


• Config section class

What is the correct way to pick up the list of "pages" via a class that inherits from System.Configuration.Section if I used a app.config like this?

<?xml version="1.0" encoding="utf-8" ?>
<configuration>

  <configSections>
    <section name="XrbSettings" type="Xrb.UI.XrbSettings,Xrb.UI" />
  </configSections>

  <XrbSettings>
    <pages>
      <add title="Google" url="http://www.google.com" />
      <add title="Yahoo" url="http://www.yahoo.com" />
    </pages>
  </XrbSettings>

</configuration>

解决方案

First you add a property in the class that extends Section:

[ConfigurationProperty("pages", IsDefaultCollection = false)]
[ConfigurationCollection(typeof(PageCollection), AddItemName = "add")]
public PageCollection Pages {
    get {
        return (PageCollection) this["pages"];
    }
}

Then you need to make a PageCollection class. All the examples I've seen are pretty much identical so just copy this one and rename "NamedService" to "Page".

Finally add a class that extends ObjectConfigurationElement:

public class PageElement : ObjectConfigurationElement {
    [ConfigurationProperty("title", IsRequired = true)]
    public string Title {
        get {
            return (string) this["title"];
        }
        set {
            this["title"] = value;
        }
    }

    [ConfigurationProperty("url", IsRequired = true)]
    public string Url {
        get {
            return (string) this["url"];
        }
        set {
            this["url"] = value;
        }
    }
}

Here are some files from a sample implementation:

• Sample config
• Collection and element classes
• Config section class
