我使用WebApi
创建了一个示例rest webservice。
这是名为Employee Controller
的控制器类。
namespace HelloWebApi.Controllers
{
public class EmployeesController : ApiController
{
private static IList<Employee> list = new List<Employee>()
{
new Employee()
{
Id = 12345, FirstName = "John", LastName = "Human",Department = 2
},
new Employee()
{
Id = 12346, FirstName = "Jane", LastName = "Public",Department = 3
},
new Employee()
{
Id = 12347, FirstName = "Joseph", LastName = "Law",Department = 2
}
};
// GET api/employees
public IEnumerable<Employee> Get()
{
return list;
}
// GET api/employees/12345
public Employee Get(int id)
{
return list.First(e => e.Id == id);
}
// POST api/employees
public void Post(Employee employee)
{
int maxId = list.Max(e => e.Id);
employee.Id = maxId + 1;
list.Add(employee);
}
// PUT api/employees/12345
public void Put(int id, Employee employee)
{
int index = list.ToList().FindIndex(e => e.Id == id);
list[index] = employee;
}
// DELETE api/employees/12345
public void Delete(int id)
{
Employee employee = Get(id);
list.Remove(employee);
}
public HttpResponseMessage Patch(int id, Delta<Employee> deltaEmployee)
{
var employee = list.FirstOrDefault(e => e.Id == id);
if (employee == null)
{
throw new HttpResponseException(HttpStatusCode.NotFound);
}
deltaEmployee.Patch(employee);
return Request.CreateResponse(HttpStatusCode.NoContent);
}
}
}
这里我使用了所有HTTP谓词方法进行插入,更新,删除。我使用了一个存储Employee对象的列表。插入,删除和更新基于此列表。但是这个程序没有数据库连接。我想知道如何在此程序中使用数据库访问。我想使用数据库中的表。我怎么能这样做?请联系任何有用的链接。
