看了很久终于有点眉目了。
首先建一个项目Asp.net MVC4 Web Application下的Web Api项目；
在Controllers文件夹下新建一个类（继承 ApiController）
public class UserController : ApiController
{
public IQueryable<User> Get()
{
return List.AsQueryable();
}
public User Get(string id)
{
User user = List.Single<User>(u => u.userNo == id);
if (user != null)
{
return user;
}
return user;
}
public bool Post(User user)
{
if (user != null)
{
List.Add(user);
return true;
}
return false;
}
public bool Put(User user)
{
if (user != null)
{
User u = List.Single<User>(mu => mu.userNo == user.userNo);
List.Remove(u);
List.Add(user);
return true;
}
return false;
}
public bool Delete(string id)
{
if (id != null)
{
User u = List.Single<User>(mu => mu.userNo == id);
List.Remove(u);
return true;
}
return false;
}
/// <summary>
/// 测试数据
/// </summary>
private static List<User> List = new List<User>();
public class User
{
public string userNo { get; set; }
public string Name { get; set; }
public string Pwd { get; set; }
}
}
需要注意一下方法名(get ,post,put,delete)和参数名(string id)和Global.asax对应。

好像其他没啥要改的，初步就这样吧。
