.net 开发 配置文件的灵活使用

配置文件的编写代码：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <section name="spring" type="spring_test.springClass,spring_test"/>
    <section name="hellowChild_1" type="spring_test.IFactory.HelloClassChild_1,spring_test"/>
    <section name="hellowChild_2" type="spring_test.IFactory.HelloClassChild_2,spring_test"/>
  </configSections>
  <spring Name="spring_class:this is a test" ></spring>
  <hellowChild_1  Name="HelloClassChild_1 : this is a  HelloClassChild_1 class"  NameSpace="spring_test.IFactory"></hellowChild_1>
  <hellowChild_2  Name="HelloClassChild_2 : this is a  HelloClassChild_2 class"  NameSpace="spring_test.IFactory"></hellowChild_2>
</configuration>

类的编写代码：

public HelloClassChild_2()
        {
             
        }
        public HelloClassChild_2(string Name, string NameSpace)
        {
            this.Name = Name;
            this.NameSpace = NameSpace;
        }

        [System.Configuration.ConfigurationProperty("Name", IsRequired = true)]
        public string Name
        {
            get
            {
                return this["Name"].ToString();
            }
            set
            {
                this["Name"] = value;
            }
        }

        [System.Configuration.ConfigurationProperty("NameSpace", IsRequired = true)]
        public string NameSpace
        {
            get
            {
                return this["NameSpace"].ToString();
            }
            set
            {
                this["NameSpace"] = value;
            }
        }
        public string GetWriteLine(string Name,string NameSpace)
        {
            return string.Format("程序加载的类为：{0} \n所属的命名空间为：{1}",  Name,  NameSpace);
        }

        public void WriteLineString(string Name, string NameSpace)
        {
            Console.WriteLine(GetWriteLine(Name,NameSpace));
        }

类的实例化代码：

  static void Main(string[] args)
        {
            var dataClass1 = System.Configuration.ConfigurationManager.GetSection("spring");
            springClass spring = dataClass1 as spring_test.springClass;
            Console.WriteLine(spring.Name);

            var dataClass2 = System.Configuration.ConfigurationManager.GetSection("hellowChild_1");
            IFactory.IHello iFactory_1 = dataClass2 as IFactory.IHello;
            iFactory_1.WriteLineString(iFactory_1.Name, iFactory_1.NameSpace);

            var dataClass3 = System.Configuration.ConfigurationManager.GetSection("hellowChild_1");
            IFactory.IHello iFactory_2 = dataClass2 as IFactory.IHello;
            iFactory_2.WriteLineString(iFactory_2.Name, iFactory_2.NameSpace);
            
            Console.Read();
        }
