如何调用其他对象的成员

　　接上文例子：

　　现在Person有一个属性 name 静态属性 eye 域 gender

  public class Person    {        public string name { get; set; }        public static object eye { get; set; }        public string gender;        public Pet pet { get; set; }public object seefrisbee(object color)        {            return string.Format("{0}看到{1}追着{2}颜色的飞盘", name,pet.name,color);        }        ~Person()        {            Console.WriteLine(name + "离开");        }    }

对属性赋值：

　　

 <object id="person" type="SpringDemo.Person,SpringDemo" singleton="true" >    <property name="pet" ref="dog" ></property>    <property name="name" value="Yahue"></property>    <property name="gender" value="男"></property>    <property name="eye" value="拥有迷离而又忧郁的眼神"></property>    <listener event="frisbeefly" method="seefrisbee">      <ref object="dog"/>    </listener>  </object>

name

  <object id="personname" type="Spring.Objects.Factory.Config.PropertyRetrievingFactoryObject, Spring.Core">    <property name="TargetObject" ref="person"></property>    <property name="TargetProperty" value="name"></property>  </object>

eye

 <!--静态属性的调用-->  <object id="personeye" type="Spring.Objects.Factory.Config.PropertyRetrievingFactoryObject, Spring.Core">    <property name="StaticProperty" value="SpringDemo.Person.eye"></property>  </object>

gender

<object id="persongender" type="Spring.Objects.Factory.Config.FieldRetrievingFactoryObject, Spring.Core">    <property name="TargetObject" ref="person"/>    <property name="TargetField" value="gender"/>  </object>

执行：

 　　　　　　 Console.WriteLine(ctx.GetObject("personname"));            Console.WriteLine(ctx.GetObject("persongender"));            Console.WriteLine(ctx.GetObject("personeye"));            Console.ReadLine();

输出结果：

　　

Yahue男拥有迷离而又忧郁的眼神

调用其他对象的方法：

Person有了静态say的方法：

　　

    public class Person    {        public string name { get; set; }        public static object eye { get; set; }        public string gender;        public Pet pet { get; set; }        public static string say(string word1,string word2,string word3)        {            return string.Format("说：{0}-{1}-{2}", word1, word2, word3);        }        public object seefrisbee(object color)        {            return string.Format("{0}看到{1}追着{2}颜色的飞盘", name,pet.name,color);        }        ~Person()        {            Console.WriteLine(name + "离开");        }    }

xml

<object id="personsay" type="Spring.Objects.Factory.Config.MethodInvokingFactoryObject, Spring.Core">    <property name="TargetType" value="SpringDemo.Person,SpringDemo"></property>    <property name="TargetMethod" value="say"></property>    <property name="Arguments">      <list>        <value>啊</value>        <value>大海啊</value>        <value>全是水</value>      </list>    </property>      </object>

Console.WriteLine(ctx.GetObject("personsay"));

输出：

说：啊-大海啊-全是水

现在有个非静态的say2方法：

 public class Person    {        public string name { get; set; }        public static object eye { get; set; }        public string gender;        public Pet pet { get; set; }        public static string say(string word1,string word2,string word3)        {            return string.Format("说：{0}-{1}-{2}", word1, word2, word3);        }        public string say2(string word1, string word2, string word3)        {            return string.Format("说：{0}-{1}-{2}", word1, word2, word3);        }        public object seefrisbee(object color)        {            return string.Format("{0}看到{1}追着{2}颜色的飞盘", name,pet.name,color);        }        ~Person()        {            Console.WriteLine(name + "离开");        }    }

  <object id="personsay2" type="Spring.Objects.Factory.Config.MethodInvokingFactoryObject, Spring.Core">    <property name="TargetObject" ref="person"></property>    <property name="TargetMethod" value="say2"></property>    <property name="NamedArguments">      <dictionary>        <entry key="word1" value="啊！"></entry>        <entry key="word2" value="大海啊！"></entry>        <entry key="word3" value="全是水！"></entry>      </dictionary>    </property>  </object>

注意ref的值是待调用对象的实例

调用：

 Console.WriteLine(ctx.GetObject("personsay2"));

执行结果：

说：啊！-大海啊！-全是水！

注意：方法参数的传递有两种方式：NamedArguments和Arguments 前者方法名和值是个键值，后者是个注入的参数顺序和方法的参数顺序对应的集合。
