读取多层配置 configSections

webconfig配置（必须在第一行）

<configuration>
<configSections>
<section name="RedisSetting" type="System.Configuration.NameValueSectionHandler" />
</configSections>

 

然后webconfig配置：

<RedisSetting>

<add key="RedisTimeOut" value="120" />
<!--连接池"写"连接对象数，通常配置为小于并发数（宁大勿小原则）-->
<add key="MaxWritePoolSize" value="10000" />
<!--连接池"读"连接对象数，通常配置为小于并发数（宁大勿小原则）-->
<add key="MaxReadPoolSize" value="100000" />


<!--Redis服务地址配置，写服务器，多个则使用英文逗号隔开192.168.100.152-->
<add key="RedisAddressWrite" value="127.0.0.1:6379" />
<!--Redis服务地址配置，读服务器，多个则使用英文逗号隔开-->
<add key="RedisAddressRead" value="127.0.0.1:6379" />

<!--通用Redis服务地址配置，写服务器，多个则使用英文逗号隔开192.168.100.152-->
<add key="CommonRedisAddressWrite" value="127.0.0.1:6379" />
<!--通用Redis服务地址配置，读服务器，多个则使用英文逗号隔开-->
<add key="CommonRedisAddressRead" value="127.0.0.1:6379" />
</RedisSetting>

 

代码实现：

NameValueCollection nameValueCollection = (NameValueCollection)ConfigurationManager.GetSection("RedisSetting");
this.RedisAddressWrite = nameValueCollection["RedisAddressWrite"];
this.RedisAddressRead = nameValueCollection["RedisAddressRead"];
this.CommonRedisAddressWrite = nameValueCollection["CommonRedisAddressWrite"];
this.CommonRedisAddressRead = nameValueCollection["CommonRedisAddressRead"];
this.MaxWritePoolSize = Convert.ToInt32(nameValueCollection["MaxWritePoolSize"]);
this.MaxReadPoolSize = Convert.ToInt32(nameValueCollection["MaxReadPoolSize"]);
this.Timeout = Convert.ToInt32(nameValueCollection["RedisTimeOut"]);
