C#定义一个类，并生成属性的例子

 class Person
     {
         private string name;
         private string age;
         private string job;

         public Person(string name,string age,string job)
         {
             this.name = name;
             this.age = age;
             this.job = job;
         }

         //因为有get方法，所以必须要有返回类型
         public string Name
         {
             get { return this.name; }
             set { this.name = value; }//赋值的来源是系统级别的value变量，系统维护的
         }

         public string Age
         {
             get { return this.age; }
             set { this.age = value; }
         }

         public string Job
         {
             get { return this.job; }
             set { this.job = value; }
         }
     }
