ConfigurationSection中的自定义IEnumerable [英] Customized IEnumerable in ConfigurationSection
问题描述
我需要创建一个简单的自定义ConfigurationSection，其中包含IEnumerable.
I need to create a simple customized ConfigurationSection with an IEnumerable inside it.
我已阅读了几篇文章和stackoverflow链接，将其作为一个简单示例: 如何在app.config中创建自定义配置部分?
I have read several articles and stackoverflow links, taking this as a simple example: How to create custom config section in app.config?
因此，我在控制台应用程序中有此配置文件部分:
So, I have this config file section inside a Console App:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<section name="Disk"
type="ConsoleApplication1_ConfigurationEnumerable.PathsConfigSection"/>
</configSections>
<Disk>
<Paths>
<Path name="one" permission="1" />
<Path name="two" permission="2" />
<Path name="three" permission="3" />
</Paths>
</Disk>
</configuration>
接下来，我将使用整个结构来管理config部分: 使用System.Configuration;
Next I have this whole structure to manage the config section: using System.Configuration;
namespace ConsoleApplication1_ConfigurationEnumerable
{
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 base.BaseGet(index) as Path;
}
set
{
if (base.BaseGet(index) != null) {
base.BaseRemoveAt(index);
}
this.BaseAdd(index, value);
}
}
protected override ConfigurationElement CreateNewElement()
{
return new Path();
}
protected override object GetElementKey(ConfigurationElement element)
{
return ((Path)element).Name;
}
}
public class PathsConfigSection : ConfigurationSection
{
public static PathsConfigSection GetConfig()
{
//return (PathsConfigSection)System.Configuration.ConfigurationManager.GetSection("Disk") ?? new PathsConfigSection();
return (PathsConfigSection)System.Configuration.ConfigurationManager.GetSection("Paths") ?? new PathsConfigSection();
}
[ConfigurationProperty("Paths")]
public Paths Paths
{
get
{
object o = this["Paths"];
return o as Paths;
}
}
}
}
这里是整个程序的program.cs: 使用系统；
And here the program.cs using the whole thing: using System;
namespace ConsoleApplication1_ConfigurationEnumerable
{
class Program
{
static void Main(string[] args)
{
var config = PathsConfigSection.GetConfig();
if (config == null || config.Paths.Count == 0)
{
Console.WriteLine("Is null or empty");
}
else
{
foreach (Path item in config.Paths)
{
Console.WriteLine("Item {0} with valuer {1}", item.Name, item.Permission);
}
}
}
}
}
这里的问题在这两行之内:
The problem here is inside this two lines:
//return (PathsConfigSection)System.Configuration
// .ConfigurationManager.GetSection("Disk") ?? new PathsConfigSection();
return (PathsConfigSection)System.Configuration
.ConfigurationManager.GetSection("Paths") ?? new PathsConfigSection();
如果我使用第二个(上面未注释)，它将返回null.
If I use the second one (uncommented above) it returns null.
如果我使用注释的，则会引发如下异常:
If I use the commented one, then it throws an exception like this:

我的错在哪里?
推荐答案
您需要使用configSections标记中指定类时，nofollow>完全合格的程序集名称:
You need to use the Fully Qualified Assembly Name when specifying the class in the configSections tag:
<configSections>
<section name="Disk"
type="ConsoleApplication1_ConfigurationEnumerable.PathsConfigSection, ConsoleApplication1"/>
</configSections>
这假定您的程序集的名称为ConsoleApplication1.如果仍然遇到异常，则可以使用以下代码确定正确的值:
This assumes that the name of your assembly is ConsoleApplication1. If you are still getting exceptions, you can determine the correct value using the the following code:
typeof(ConsoleApplication1_ConfigurationEnumerable.PathsConfigSection).FullName
.ToString()
顺便说一句:您的名称空间很奇怪.命名标准建议您在分隔名称空间层次结构时使用点(.):
BTW: Your namespace is odd. Naming standard suggest that you use the dot (.) when separating namespace hierarchies:
namespace ConsoleApplication1.ConfigurationEnumerable
