從C＃自定義配置文件

Question

嗨Retriving信息我有一個配置文件作爲

<environments selectedEnvironment="10" selectedSite="UK"> 
<environment env="10"> 
<secure> 
    <site name="UK" url="https://www.google.co.uk/"/> 
    <site name="US" url="https://www.google.com/"/> 
</secure> 
<content> 
    <site name="UK" isoCode="UK" url="http://www.yahoo.co.uk"/> 
    <site name="US" isoCode="UK" url="http://www.yahoo.com"/> 
</content> 
<office url="http://google-office.com"/> 
</environment> 
<environment env="24"> 
<secure> 
    <site name="UK" url="https://yahoo.co.uk"/> 
    <site name="US" url="https://yahoo.com"/> 
</secure> 
<content> 
    <site name="UK" url="https://google.co.uk"/> 
    <site name="US" url="https://google.com"/> 
</content> 
<office url="http://yahoo-docs.com"/> 
</environment> 
</environments> 

我想根據selectedEnvironment和selectedSite

我的電流值來選擇安全，內容和辦公室的網址該代碼是：

部分：

public class EnvironmentsConfigurationSection : ConfigurationSection 
{ 
    [ConfigurationProperty("selectedEnvironment", IsRequired = true)] 
    public string SelectedEnvironment 
    { 
     get { return this["selectedEnvironment"].ToString(); } 
     set { this["selectedEnvironment"] = value; } 
    } 
    [ConfigurationProperty("name", IsRequired = true)] 
    public string EnvironmentName 
    { 
     get { return this["name"].ToString(); } 
     set { this["name"] = value; } 
    } 
    [ConfigurationProperty("selectedSite", IsRequired = true)] 
    public string SelectedSite 
    { 
     get { return this["selectedSite"].ToString(); } 
     set { this["selectedSite"] = value; } 
    } 
    [ConfigurationProperty("environment", IsDefaultCollection = true, Options = ConfigurationPropertyOptions.IsRequired)] 
    [ConfigurationCollection(typeof(EnvironmentConfigurationElement), AddItemName = "selectedEnv")] 
    public EnvironmentConfigurationElement EnvironmentConfig 
    { 
     get { return this["environment"] as EnvironmentConfigurationElement; } 
    } 
} 

ElementColle ction：

public class EnvironmentConfigurationCollection : ConfigurationElementCollection 
{ 
    public new EnvironmentConfigurationElement this[string key] 
    { 
     get { return this.BaseGet(key) as EnvironmentConfigurationElement; } 
    } 
    public EnvironmentConfigurationElement this[int index] 
    { 
     get { return base.BaseGet(index) as EnvironmentConfigurationElement; } 
     set 
     { 
      // Remove any existing element 
      if (base.BaseGet(index) != null) 
      { 
       base.BaseRemoveAt(index); 
      } 
      this.BaseAdd(index, value); 
     } 
    } 
    protected override ConfigurationElement CreateNewElement() 
    { 
     return new EnvironmentConfigurationElement(); 
    } 
    protected override object GetElementKey(ConfigurationElement element) 
    { 
     return ((EnvironmentConfigurationElement)element).Environment; 
    } 
} 

元素：

public class EnvironmentConfigurationElement:ConfigurationElement 
{ 
    [ConfigurationProperty("env", IsRequired = true, IsKey = true)] 
    public string Environment 
    { 
     get { return this["env"].ToString(); } 
     set { this["env"] = value; } 
    } 

    [ConfigurationProperty("secure", IsRequired = true)] 
    [ConfigurationCollection(typeof(CheckoutConfigurationCollection), AddItemName   ="site")] 
    public CheckoutConfigurationCollection Secure 
    { 
     get { return this["secure"] as SecureConfigurationCollection; } 
    } 
    [ConfigurationProperty("content", IsRequired = true)] 
    [ConfigurationCollection(typeof(ContentConfigurationCollection), AddItemName = "site")] 
    public CheckoutConfigurationCollection Content 
    { 
     get { return this["content"] as CheckoutConfigurationCollection; } 
    } 
    [ConfigurationProperty("office", IsRequired = true)] 
    [ConfigurationCollection(typeof(officeBaseUrlConfigurationElement), AddItemName = "url")] 
    public BackOfficeBaseUrlConfigurationElement Office 
    { 
     get { return this["office"] as officeBaseUrlConfigurationElement; } 
    } 
} 

當我運行使用

EnvironmentConfiguration = (EnvironmentsConfigurationSection)ConfigurationManager.GetSection("testExecutionSettings/environments"); 

我得到屬性的錯誤代碼 「ENV」 沒有找到，即使它的部分目前的元素..

任何人都可以告訴我在這種情況下做什麼？

如果你是開放的嘗試Linq2Xml和XPath

string selectedEnvironment="10"; 
string selectedSite= "UK"; 

var xpath = string.Format("//environments[@selectedEnvironment='{0}' and @selectedSite='{1}']//*[@url]", 
          selectedEnvironment, 
          selectedSite); 

var xDoc = XDocument.Parse(xml); //XDocument.Load(filename) 

var urls = xDoc.XPathSelectElements(xpath) 
       .Select(e => e.Attribute("url").Value) 
       .ToList();
