在哪里可以找到一些开源代码来读取/写入配置文件?
我不喜欢 .NET Framework 中的标准配置机制。 (ConfigurationManager、ConfigurationSection 等)。
我想要更简单的能力来管理我的应用程序配置文件。
例如,我想在我的应用程序文件夹中创建一个名为“Settings”的文件夹。有几个名为的配置文件。
请看一下:
Settings:
- smtp.config
- database.config
- something.config
假设“smtp.config”文件具有以下简单结构:
<smtp>
<username>something</username>
<hostname>something</hostname>
...
</smtp>
我想创建以下类:
public class MySmtpSettings : SomeBaseClassFromSomeConfigLibrary
{
// May be some simple attributes here
public string username;
// May be some simple attributes here. For example:
// Like XPath: [ConfigAttr("smtp\username")], or simply: ConfigAttr("username")
public string hostname;
...
// Only code containing properties declaration.
}
我想使用我的设置对象,例如:
var settings = new MySmtpSettings("smtp.config");
var hostname = settings.Hostname;
我不想使用 ConfigurationSection 类。看起来很难。
你知道我在哪里可以找到一个可扩展的、简单的开源库吗?
UPD。
@jjrdk:谢谢您的回答,但使用 ConfigurationSection 类我通常会创建下一个代码:
public class MyConfigurationSection : ConfigurationSection
{
[ConfigurationProperty("username")]
public ConfigurationTextElement<string> Username
{
get { return (ConfigurationTextElement<string>)this["username"]; }
set { this["username"] = value; }
}
// ...
{
public class ConfigurationTextElement<T> : ConfigurationElement
{
private T _value;
protected override void DeserializeElement(XmlReader reader, bool serializeCollectionKey)
{
_value = (T)reader.ReadElementContentAs(typeof(T), null);
}
public T Value
{
get { return _value; }
}
}
它看起来并不简单。也许我做了一些我不明白的事情?
I don't like standard mechanism of configuration in the .NET Framework. (ConfgurationManager, ConfigurationSection and other).
I want a simpler ability to manage my application configuration files.
For example, I want to create a folder named "Settings" in my application folder. There are several config files named.
Please, take a look:
Settings:
- smtp.config
- database.config
- something.config
Assume, the "smtp.config" file has the following simple stucture:
<smtp>
<username>something</username>
<hostname>something</hostname>
...
</smtp>
And I want to create the following class:
public class MySmtpSettings : SomeBaseClassFromSomeConfigLibrary
{
// May be some simple attributes here
public string username;
// May be some simple attributes here. For example:
// Like XPath: [ConfigAttr("smtp\username")], or simply: ConfigAttr("username")
public string hostname;
...
// Only code containing properties declaration.
}
And I want to use my setting object like:
var settings = new MySmtpSettings("smtp.config");
var hostname = settings.Hostname;
I don't want to use the ConfigurationSection class. It looks very hard.
Do you know where I can find an extensible, simple open source library for this?
UPD.
@jjrdk: Thank you for your answer but using the ConfigurationSection class I usually create the next code:
public class MyConfigurationSection : ConfigurationSection
{
[ConfigurationProperty("username")]
public ConfigurationTextElement<string> Username
{
get { return (ConfigurationTextElement<string>)this["username"]; }
set { this["username"] = value; }
}
// ...
{
public class ConfigurationTextElement<T> : ConfigurationElement
{
private T _value;
protected override void DeserializeElement(XmlReader reader, bool serializeCollectionKey)
{
_value = (T)reader.ReadElementContentAs(typeof(T), null);
}
public T Value
{
get { return _value; }
}
}
It does not look simple. Maybe I do something I do not understand?

如果您不想使用 ConfigurationManager,您可以可能想看看一些对象序列化器。
您还可以使用众多 依赖注入 (DI)/
作为旁注,您甚至可以使用 LINQ-to-XML 或一个.Net Framework 中的许多其他 XML/文本阅读器。即使是好的 <a href="http://www.codeproject.com/KB/cs/cs_ini.aspx" rel="nofollow">INI 文件。
If you don't want to use the ConfigurationManager you might want to look at a few of the object serializers.
You could also use one of the many Dependency Injection (DI)/Inversion of Control (IoC) frameworks... but if you don't like the complexity behind ConfigurationManager I'm sure you fill find DI even less appealing.
As a side note could you even use LINQ-to-XML or one of the many other XML/Text readers within the .Net Framework. Even good-ole INI files.
我使用了一段代码,我一开始不知道它来自哪里,但是使用 Google 代码搜索我设法在这里找到它: http://m3dafort2d.googlecode.com/svn/trunk/projects/NCode/NCode/Configuration/
然后我像这样使用它:
这是为了在 IoC 场景中使用而设置的,但您可能可以找到一种以正常方式使用它的方法。
我通常只在 IoC 容器中配置 ISettingsProvider,然后也配置 AppSettings 类。然后我可以将该类注入到任何需要设置的组件中。如果我想将配置设置类分组为逻辑集合,我还可以将它们拆分为多个类。
如果您想读取 web.config 中与 AppSettings 不同的位置的设置,只需实现另一个 ISettingsProvider 即可。我曾经为 SQL Server 创建了一个。
I have used a piece of code that I don't know where it came from in the beginning, but using Google Code Search I managed to find it here: http://m3dafort2d.googlecode.com/svn/trunk/projects/NCode/NCode/Configuration/
I then use it like this:
This is setup to be used in a IoC scenario, but you can probably find a way to use it in a normal way.
I usually just configure the ISettingsProvider in the IoC container and then I configure the AppSettings class as well. I can then just inject that class into any component that need the settings. I can also split the configuration settings classes into several class if I want to group them into logical collections.
If you want to read settings for somewhere different than the AppSettings in web.config, simply implement another ISettingsProvider. I created one for SQL Server at one point.
编写一个 ConfigurationSectionHandler 并不难;当 ConfigurationManager 调用您的代码时,只需遍历作为参数提供给您的 XML 中的节点即可。您编写一种方法(可能还有一些帮助程序)来返回您想要的配置数据结构。对于简单的 XML,该方法也可以非常简单。请参阅 http://msdn.microsoft.com/en-us/library 中的示例/ms228056.aspx。
用作
Writing a ConfigurationSectionHandler is not hard; it's simply a matter of traversing the nodes in the XML that's given to you as a parameter when the ConfigurationManager calls your code. You write one method (and probably a few helpers) that returns the data structure that you want for your configuration. For simple XML, the method can be quite simple as well. See the samples at http://msdn.microsoft.com/en-us/library/ms228056.aspx.
