.NET 中的自定义配置

发布于 2024-07-16 20:33:24 字数 848 浏览 8 评论 0原文

我看到有关 .NET 中自定义配置的简单示例。我的情况有点复杂，有嵌套节点。

我希望能够从配置文件中读取此内容：

 <environments>

<environment name="live" url="http://www.live.com">
  <server name="a" IP="192.168.1.10"></server>
  <server name="b" IP="192.168.1.20"></server>
  <server name="c" IP="192.168.1.30"></server>      
</environment>

<environment name="dev" url="http://www.dev.com">
  <server name="a" IP="192.168.1.10"></server>
  <server name="c" IP="192.168.1.30"></server>
</environment>

<environment name="test" url="http://www.test.com">
  <server name="b" IP="192.168.1.20"></server>
  <server name="d" IP="192.168.1.40"></server>
</environment></environments>

如果有人可以为此提供一些代码，我将不胜感激。

谢谢！

I am seeing simple examples regarding custom configuration in .NET. My case is a bit more complex, with nested nodes.

I'd like to be able to read this from the configuration file:

 <environments>

<environment name="live" url="http://www.live.com">
  <server name="a" IP="192.168.1.10"></server>
  <server name="b" IP="192.168.1.20"></server>
  <server name="c" IP="192.168.1.30"></server>      
</environment>

<environment name="dev" url="http://www.dev.com">
  <server name="a" IP="192.168.1.10"></server>
  <server name="c" IP="192.168.1.30"></server>
</environment>

<environment name="test" url="http://www.test.com">
  <server name="b" IP="192.168.1.20"></server>
  <server name="d" IP="192.168.1.40"></server>
</environment></environments>

If anyone could provide some code for that, I'd appreciate it.

Thanks!

您可以通过实现从 ConfigurationElement 类继承的自定义配置类来阅读此内容。

以下是“server”元素的示例：

public class ServerElement: ConfigurationElement
{
    [ConfigurationProperty("name", IsRequired = true, IsKey = true)]
    public string Name
    {
        get { return ((string)base["name"]); }
        set { base["name"] = value; }
    }

    ...
}

环境元素实际上是一个集合，可以这样实现：

public class EnvironmentElement: ConfigurationElementCollection
{
    protected override ConfigurationElement CreateNewElement(string elementName)
    {
        return new ServerElement(...);
    }
}

You can read this by implementing custom configuration classes inheriting from the ConfigurationElement class.

Here is an example of the "server" element:

public class ServerElement: ConfigurationElement
{
    [ConfigurationProperty("name", IsRequired = true, IsKey = true)]
    public string Name
    {
        get { return ((string)base["name"]); }
        set { base["name"] = value; }
    }

    ...
}

The environment element is actually a collection and could be implemented like this:

public class EnvironmentElement: ConfigurationElementCollection
{
    protected override ConfigurationElement CreateNewElement(string elementName)
    {
        return new ServerElement(...);
    }
}
