appSettings太简单，为每个程序自定义配置节点太复杂，因此要解决app.config&web.config自定义配置的复用问题。
1.读取不依赖SectionName,根节点可以定义为任何名称。
2.足够简单，配置项采用name value的形式；足够复杂，采用树型结构，每个节点都可以有多个配置项和子节点。
3.使用简单，采用路径简化配置项的读取。如: config.Get<string>("root.sub.item-test")。
一、调用方式：1.配置文件：
<?xmlversion="1.0" encoding="utf-8"?><configuration><configSections><sectionname="node"type="Onion.Configuration.AppConfig.ConfigSection,Onion.Configuration"/></configSections><nodename="root"><items><itemname="version"value="1.0.0.1"/></items><nodes><nodename="runtime"><items><itemname="debug"value="false"/><itemname="ioc"value="IoC.Contianer.StructureMapIoC"/></items></node><nodename="upload"><items><itemname="auth"value="true"/><itemname="path"value="~/upload"/><itemname="url"value="~/Upload/Index"/></items></node><nodename="captcha"><items><itemname="timeout"value="3000"/><itemname="url"value="~/Captcha/Index"/></items></node><nodename="oauth2"><items><itemname="disabled"value="false"/><itemname="callback"value="/Home/ExternalLoginCallBack?PRoviderName="/></items><nodes><nodename="QQclient"><items><itemname="disabled"value="false"/><itemname="method"value="get"/><itemname="key"value="9233e24d"/><itemname="secret"value="1ac35907-7cfa-4079-975c-959b98d23a95"/></items></node><nodename="weiboclient"><items><itemname="disabled"value="true"/><itemname="method"value="post"/><itemname="key"value="0cdea8f3"/><itemname="secret"value="dc679dbb-7e75-44f7-a99e-5359259fc94b"/></items></node></nodes></node></nodes></node></configuration>
2.调用代码：
[Fact]publicvoidTests()
{varconfig =newAppConfigAdapter();
Assert.True(config.Get<string>("version") =="1.0.0.1");
Assert.True(config.Get<bool>("runtime.debug") ==false);
Assert.True(config.Get<string>("runtime.ioc") =="IoC.Contianer.StructureMapIoC");
Assert.True(config.Get<bool>("upload.auth") ==true);
Assert.True(config.Get<string>("upload.path") =="~/upload");
Assert.True(config.Get<string>("upload.url") =="~/Upload/Index");
Assert.True(config.Get<int>("captcha.timeout") ==3000);
Assert.True(config.Get<string>("captcha.url") =="~/Captcha/Index");
Assert.True(config.Get<bool>("oauth2.disabled") ==false);
Assert.True(config.Get<string>("oauth2.callback") =="/Home/ExternalLoginCallBack?ProviderName=");
Assert.True(config.GetNode("oauth2").Nodes.Any(o => o.GetItem<bool>("disabled")));foreach(varnodeinconfig.GetNode("oauth2").Nodes)
{if(node.Name =="qqclient")
{
Assert.True(node.GetItem<bool>("disabled") ==false);
Assert.True(node.GetItem<string>("method") =="get");
Assert.True(node.GetItem<string>("key") =="9233e24d");
Assert.True(node.GetItem<string>("secret") =="1ac35907-7cfa-4079-975c-959b98d23a95");
}elseif(node.Name =="weiboclient")
{
Assert.True(node.GetItem<bool>("disabled") ==true);
Assert.True(node.GetItem<string>("method") =="post");
Assert.True(node.GetItem<string>("key") =="0cdea8f3");
Assert.True(node.GetItem<string>("secret") =="dc679dbb-7e75-44f7-a99e-5359259fc94b");
}
}
}
二、接口定义：1.配置项定义：IItem接口定义最基础的配置项，只包含Name和Value属性。
public interface IItem
{
string Name { get; set; }
string Value { get; set; }
}
2.配置节点定义：INode接口定义了配置节点的树形结构
public interface INode
{
string Name { get; set; }
IEnumerable<IItem> Items { get; set; }
IEnumerable<INode> Nodes { get; set; }
string GetItem(string itemName);
T GetItem<T>(string itemName);
}
3.读取接口定义：IConfig接口定义了配置节点和配置项的读取
public interface IConfig
{
INode GetNode(string nodeName);
string Get(string nameOrPath);
T Get<T>(string nameOrPath);
}
以上3个接口定义了所有的逻辑。
三、接口实现：1.自定义ItemElement（IItem）和ItemElementCollection用于实现单个节点的配置项读取。
