第一步创建MVC4项目：

选择api

第二步：在Models下创建一个Student类：

namespace TestOne.Models
    {
        public class Student
        {
            public int id { get; set; }
            public string name { get; set; }
            public string sex { get; set; }
            public long grade { get; set; }
        }
    }

第三步：添加一个 Controler控制器：

namespace TestOne.Controllers
    {
        public class GetStudentController : ApiController
        {
            private static IList<Student> students = new List<Student>  
            {   
                new Student(){ id=1,name="zzg", sex="男",grade=12 },     
                new Student(){ id=2,name="sss", sex="女",grade=23  },  
            };
    
            public IEnumerable<Student> GetStudent()
            {
                return students;
            }
    
            public Student GetStudentById(int id)
            {
                return students.FirstOrDefault(x => x.id == id);
            }  
      
    
        }
    }

注意此处继承的是ApiControler

第四步：运行项目，点击右上角的api：

第五步：使用Poster工具调试接口：  
接口： [http://localhost:5579/api/GetStudent][http_localhost_5579_api_GetStudent]  
method：get  
返回结果：  
\[\{"id":1,"name":"zzg","sex":"男","grade":12\},  
\{"id":2,"name":"sss","sex":"女","grade":23\}\]
