中的ConfigurationSection定製的IEnumerable II

Question

原來的問題和代碼：Customized IEnumerable in ConfigurationSection

推進在解決這一與@Daniel Hilgarth答案我已經改變（app.config）中這樣的：

<section name="Disk" 
     type="ConsoleApplication1_ConfigurationEnumerable.PathsConfigSection"/> 

本之一：

<section name="Disk" 
      type="ConsoleApplication1_ConfigurationEnumerable.PathsConfigSection, 
      ConsoleApplication1_ConfigurationEnumerable"/> 

現在，我這還有一個例外：

System.Configuration.ConfigurationErrorsException was unhandled 
    HResult=-2146232062 
    Message=Unrecognized element 'Path'. (C:\Users\blackberry\Desktop\ConsoleApplication1_ConfigurationEnumerable\ConsoleApplication1_ConfigurationEnumerable\bin\Debug\ConsoleApplication1_ConfigurationEnumerable.vshost.exe.config line 9)

Answer 1

嘗試添加下列屬性的PathsConfigSection.Paths屬性：

[ConfigurationCollection(typeof(Paths), AddItemName = "Path")] 

現在應該是這樣的：

[ConfigurationProperty("Paths")] 
    [ConfigurationCollection(typeof(Paths), AddItemName = "Path")] 
    public Paths Paths 
    { 
     get 
     { 
      var o = this["Paths"]; 
      return o as Paths; 
     } 
    }

你的配置應該是現在這個樣子：

<?xml version="1.0" encoding="utf-8" ?> 
<configuration> 
    <configSections> 
    <section name="Disk" type="ConsoleApplication1.DiskConfigSection, ConsoleApplication1"/> 
    </configSections> 
    <Disk> 
    <Paths> 
     <Path name="one" permission="1" /> 
     <Path name="two" permission="2" /> 
     <Path name="three" permission="3" /> 
    </Paths> 
    </Disk> 
</configuration> 

你的課堂現在應該廁所k像這樣：

using System.Configuration; 

namespace ConsoleApplication1 
{ 
class Program 
{ 
    static void Main(string[] args) 
    { 
     var t = DiskConfigSection.GetConfig(); 
     // Put a breakpoint on the line after this and put a watch on t 
    } 
} 

public class Path : ConfigurationElement 
{ 
    [ConfigurationProperty("name", IsRequired = true)] 
    public string Name 
    { 
     get 
     { 
      return (string)this["name"]; 
     } 
    } 

    [ConfigurationProperty("permission", IsRequired = true)] 
    public string Permission 
    { 
     get 
     { 
      return (string)this["permission"]; 
     } 
    } 
} 

public class Paths : ConfigurationElementCollection 
{ 
    public Path this[int index] 
    { 
     get 
     { 
      return BaseGet(index) as Path; 
     } 
     set 
     { 
      if (BaseGet(index) != null) 
      { 
       BaseRemoveAt(index); 
      } 
      BaseAdd(index, value); 
     } 
    } 

    protected override ConfigurationElement CreateNewElement() 
    { 
     return new Path(); 
    } 
    protected override object GetElementKey(ConfigurationElement element) 
    { 
     return ((Path)element).Name; 
    } 
} 

public class DiskConfigSection : ConfigurationSection 
{ 
    public static DiskConfigSection GetConfig() 
    { 
     var b = ConfigurationManager.GetSection("Disk") != null; 
     return b ? (DiskConfigSection)ConfigurationManager.GetSection("Disk") : new DiskConfigSection(); 
    } 

    [ConfigurationProperty("Paths")] 
    [ConfigurationCollection(typeof(Paths), AddItemName = "Path")] 
    public Paths Paths 
    { 
     get 
     { 
      var o = this["Paths"]; 
      return o as Paths; 
     } 
    } 
} 
} 

我已經在控制檯應用程序中進行了測試，配置完全加載。
