C# 读取配置文件

App.config:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <appSettings>
    <add key="factory" value="Abstract_Dactory.SummerSkinFactory"/>
  </appSettings>
</configuration>

C#:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Configuration;////导入命名空间(记得在解决方案资源管理器里的“引用”中添加“System.Configuration”)

namespace Abstract_Dactory
{
    class Program
    {
        static void Main(string[] args)
        {
            //读取配置文件
            string factoryType =ConfigurationManager.AppSettings["factory"];
            Console.WriteLine(factoryType);  
            Console.ReadKey();
        }
    }
}
