c# – 如何读取app.config中定义的属性的值？

我有一个app.config文件,其形式为：

<?xml version="1.0" encoding="utf-8" ?>
  <configuration>
    <system.serviceModel>
      <client>
        <endpoint address="http://something.com"
        binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IFileTransfer"
        contract="ABC" name="XXX" />
        <endpoint address="http://something2.com"
        binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IFileTransfer"
        contract="ABC2" name="YYY" />
      </client>
    </system.serviceModel>
  </configuration>

我想读取节点端点的属性“address”的值,其名称为“XXX”.请告诉我该怎么做！

(继续讨论与marc_s讨论.抱歉把文字放在这里,因为评论不允许格式化代码)
@marc_s：我使用下面的代码来读取上面的文件,但它显示clientSection.Endpoints有0个成员(Count = 0).请帮忙！

public MainWindow()
    {
        var exeFile = Environment.GetCommandLineArgs()[0];
        var configFile = String.Format("{0}.config",exeFile);
        var config = ConfigurationManager.OpenExeConfiguration(configFile);
        var wcfSection = ServiceModelSectionGroup.GetSectionGroup(config);
        var clientSection = wcfSection.Client;
        foreach (ChannelEndpointElement endpointElement in clientSection.Endpoints)
        {
            if (endpointElement.Name == "XXX")
            {
                var addr = endpointElement.Address.ToString();
            }
        }
    }

解决方法

你真的不需要–WCF运行时将为你做所有这些.

如果你真的必须 – 无论出于何种原因 – 你可以这样做：

using System.Configuration;
using System.ServiceModel.Configuration;

ClientSection clientSettings = ConfigurationManager.GetSection("system.serviceModel/client") as ClientSection;

string address = null;

foreach(ChannelEndpointElement endpoint in clientSettings.Endpoints)
{
   if(endpoint.Name == "XXX")
   {
      address = endpoint.Address.ToString();
      break;
   }
}
