• C#动态属性(.NET Framework4.5支持)


    获取方法:

      /*
    
    使用方法:
      
      1. 在web.config 的<configSections> 节点中添加
        <section name="customConfigs" type="FortuneLab.Core.Configurations.CustomConfigsSection,FortuneLab.Core"/>
         
      2. 在web.config 中添加 如下配置
          <customConfigs>
            <cfg name="dbCommands" fliePath="ConfigFilesdbCommands.config"/>
            <!--根据需要可以继续添加其他 cfg 配置,如
                <cfg name="dbConnections" fliePath="ConfigFilesdbConnections.config"/>
                <cfg name="params" fliePath="ConfigFilesparams.config"/>
            -->
          </customConfigs>    
       3. cs中通过 ConfigManager.Configs["dbCommands"] 获取
         例如 dbCommands 的配置文件内容如下
    <?xml version="1.0" encoding="utf-8"?>
    <Container>
      <A A1="" A2="">
        <A3><![CDATA[ xxxxxx ]]></A3>
        <A4>
          <Parameters>
            <Param name="p1"></Param>
            <Param name="p2"></Param>
            <Param name="p3"></Param>
          </Parameters>
        </A4>
      </A>
    </Container>
         
        取A : ConfigManager.Configs["dbCommands"].A
        取A1: ConfigManager.Configs["dbCommands"].A.A1
        取A2: ConfigManager.Configs["dbCommands"].A.A2
    	取A3: ConfigManager.Configs["dbCommands"].A.A3
    	取A4: ConfigManager.Configs["dbCommands"].A.A4
    	取Parameters: ConfigManager.Configs["dbCommands"].A.Parameters
    	取Parameters 第一个: ConfigManager.Configs["dbCommands"].A.Parameters["p1"] 或者 ConfigManager.Configs["dbCommands"].A.Parameters[0]
    
    	终极用法: 可以将任意一个节点转换为IDictionary<string, dynamic>, 然后再操作
    	IDictionary<string, dynamic> dict = ConfigManager.Configs["dbCommands"].A as IDictionary<string, dynamic>;
    	取A1: dict["A1"]
    	取A2: dict["A2"]
    	取A3: dict["A3"]
    	取A4: dict["A4"]
    
    	IDictionary<string, dynamic> dict1 = dict["A4"] as IDictionary<string, dynamic>;
    	取Parameters: dict1["Parameters"]
    
    	IDictionary<string, dynamic> dict2 = dict1["Parameters"] as IDictionary<string, dynamic>;
    	取Parameters 第一个: dict2["p1"] 或 dict2[0]
    
    
    	备注: 
    		任何使用都可以使用HasMember("memberName"), 取检查是否有这个成员
    		如果是集合, 可用使用foreach
    		有Value属性,可以取到尖括号之间的内容,比如<A>hahah</A> , 可以用A.Value 取到其中的值,所以请避免显示定义Value属性
