app.config配置方案1:   

 1 <?xml version="1.0" encoding="utf-8" ?>
 2 <configuration>
 3 <configSections>
 4 <section name="orders" type="TestSection.SectionClass.OrderSection,TestSection"></section>
 5 </configSections>
 6 
 7 <orders companyID="12">
 8 <order number="11" amount="333"></order>
 9 <order number="22" amount="444"></order>
10 </orders>
11 </configuration>

　引用1：　　

1   static void Main(string[] args)
2         {
3             OrderSection config = (OrderSection)ConfigurationManager.GetSection("orders");
4             Console.WriteLine(config.CompanyID);
5             Console.WriteLine(config.Orders[0].Number);
6             Console.WriteLine(config.Orders[0].Amount);
7             Console.ReadKey();
8         }
