怎样在运行时读取及修改app.config文件中的wcf配置内容？
服务端app.config文件内容如下：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.serviceModel>
<services>
<service behaviorConfiguration="NewBehavior" name="Learn.Library.WCF.MyService">
<host>
<baseAddresses>
<add baseAddress="http://localhost:8080/MyService" />
</baseAddresses>
</host>
<endpoint address="" binding="basicHttpBinding"
contract="Learn.Library.WCF.IContract" />
<endpoint address="mex" binding="mexHttpBinding"
contract="IMetadataExchange" />
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="NewBehavior">
<serviceMetadata httpGetEnabled="true" />
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
</configuration>

我想在运行时读取及修改
<add baseAddress="http://localhost:8080/MyService" />
引号中间的字符串，如何实现？

[解决办法]
Configuration conf = ConfigurationManager.OpenExeConfiguration(Assembly.GetEntryAssembly().Location);
ServiceModelSectionGroup svcmod = (ServiceModelSectionGroup)conf.GetSectionGroup("system.serviceModel");
foreach (ServiceElement el in svcmod.Services.Services)
{
Type svcType = Type.GetType(el.Name + "," + "");
if (svcType == null)
throw new Exception("Invalid");
aServiceHost = new ServiceHost(svcType);
}
