C# App.config 自定义 配置节

（１）App.config

<?xml version="1.0" encoding="utf-8" ?>

<configuration>

<configSections>

<section name="color" type="System.Configuration.NameValueSectionHandler" />

<section name="message" type="System.Configuration.DictionarySectionHandler"/>

<section name="name" type="System.Configuration.SingleTagSectionHandler"/>

</configSections>

<color>

<add key="red" value="#ff0000"/>

<add key="green" value="#00ff00"/>

<add key="blue" value="#0000ff"/>

</color>

<message>

<add key="welcome" value="你好,欢迎"/>

</message>

<name firstName="陈" lastName="明明"/>

</configuration>

对于自定义的配置节，应该先在 <configSections>中声明要配置的节与类型，如着色部分，接着，在后面定义要配置的具体内容，正如定义一个变量。

(2)配置节的访问

public static void Main(string[] args)

{

//get color

NameValueCollection color = (NameValueCollection)ConfigurationManager.GetSection("color");

foreach (String str in color.AllKeys) {

Console.WriteLine(str+":"+color[str]);

}

//get message

IDictionary message = (IDictionary)ConfigurationManager.GetSection("message");

foreach (String str in message.Keys) {

Console.WriteLine(str+":"+message[str]);

}

// get name

IDictionary name = (IDictionary)ConfigurationManager.GetSection("name");

foreach (String str in name.Keys)

{

Console.WriteLine(str + ":" + name[str]);

}

//Console.WriteLine(name["firstName"]);

Console.Read();

}
