什么是拿起通过一个类继承自System.Configuration.Section如果我用这样的的app.config页面列表中选择正确的方法是什么?

 < XML版本=1.0编码=UTF-8&GT?;
<结构>

  < configSections>
    <节名称=XrbSettingsTYPE =Xrb.UI.XrbSettings,Xrb.UI/>
  < / configSections>

  < XrbSettings>
    <网页>
      <添加标题=谷歌URL =htt​​p://www.google.com/>
      <添加标题=雅虎URL =htt​​p://www.yahoo.com/>
    < /页>
  < / XrbSettings>

< /结构>
 

解决方案

首先,你在扩展部分类添加属性:

  [的ConfigurationProperty(页,IsDefaultCollection = FALSE)]
[ConfigurationCollection(typeof运算(PageCollection),AddItemName =加)
公共PageCollection页面{
    得到 {
        返程(PageCollection)本[页];
    }
}
 

然后,你需要做一个PageCollection类。所有我见过的例子是pretty的很多相同的,从而只是复制这个并重新命名NamedService到页面。

最后补充扩展ObjectConfigurationElement类:

 公共类PageElement:ObjectConfigurationElement {
    [的ConfigurationProperty(标题,IsRequired =真)
    公共字符串名称{
        得到 {
            返程(串)本[标题];
        }
        组 {
            这种[标题] =价值;
        }
    }

    [的ConfigurationProperty(URL,IsRequired =真)
    公共字符串URL {
        得到 {
            返程(串)本[网址];
        }
        组 {
            这种[网址] =值;
        }
    }
}

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;
        }
    }
}
