c# ConfigurationSection

怎么把自己的配置文件配置到app.config中？

方案1：在app.config中添加

<!--应用配置-->
<appSettings configSource="Conf\AppSettings.config" />

如果我需要自己定义单独的多个配置文件，又该怎么处理才可以把配置文件添加app.config中呢？

方案2：定义ConfigurationSection类

MyConfigurationSection

public class MyConfigurationSection : ConfigurationSection
{
[ConfigurationProperty("", IsDefaultCollection = true)]
public KeyValueConfigurationElementCollection My
{
get { return (KeyValueConfigurationElementCollection)base[""]; }
}

public string GetValueByKey(string key)
{
foreach (KeyValueConfigurationElement item in this.My)
{
if (item.Key == key)
return item.Value;
}

return string.Empty;
}

//[ConfigurationProperty("configSource", IsRequired = false)]
//public string ConfigSource
//{
//    get { return (string)base["configSource"]; }
//    set
//    {
//        base["configSource"] = value;
//    }
//}
}

KeyValueConfigurationElementCollection

public class KeyValueConfigurationElementCollection : ConfigurationElementCollection
{
protected override ConfigurationElement CreateNewElement()
{
return new KeyValueConfigurationElement();
}

protected override object GetElementKey(ConfigurationElement element)
{
return (element as KeyValueConfigurationElement).Key;
}

public override ConfigurationElementCollectionType CollectionType
{
get { return ConfigurationElementCollectionType.BasicMap; }
}

protected override string ElementName
{
get { return "add"; }
}
}

KeyValueConfigurationElement

public class KeyValueConfigurationElement : ConfigurationElement
{
[ConfigurationProperty("key", IsRequired = true)]
public string Key
{
get { return (string)base["key"]; }
set { base["key"] = value; }
}

[ConfigurationProperty("value", IsRequired = true)]
public string Value
{
get { return (string)base["value"]; }
set { base["value"] = value; }
}
}

修改app.config配置文件：

<configSections>
<section name="my" type="DTCore.MyConfigurationSection,DTCore"/>
</configSections>

<mre configSource="Conf\My_Settings.config" />

Conf\My_Settings.config

<?xml version="1.0" encoding="utf-8"?>
<my>
<add key="DT.AKey" value="c key"/>
<add key="DT.CKey.RIPPRB" value="the value"/>
</my>

怎么调用：

MyConfigurationSection mySection=(MyConfigurationSection)ConfigurationManager.GetSection("my");
string value=mySection.GetValueByKey("DT.AKey");
