用Ninject 实现webapi ApiController 示例源码

【核心代码】

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web.Http;
using Model;
using Newtonsoft.Json;
using Strategy;
using Service;
using Ninject;
namespace WebSite.Controllers
{
	public class ValuesController : ApiController
	{
		public static IList<Product> products = new List<Product>()
		{
			new Product{Id="1",ProductName="Iphone4s",Price=3788},
			new Product{Id="2",ProductName="Ipad3",Price=2788}
		};
		// GET api/values/
		public string Get()
		{
			var json = JsonConvert.SerializeObject(products);
			return json;
		}

		// GET api/values/5
		public string Get(decimal id)
		{
			IKernel kernel = new StandardKernel();

			decimal result = products.Sum(p => p.Price);
			decimal para;
			if (id > 0 && id < 100)
			{
				para = id / 10;
			}
			else
				para = id;
			NinjectBinder binder = new NinjectBinder(kernel, result, para);//这里应该到全局里注册的

			var sum = "";
			switch (id.ToString()) //这里使用了固定的值 可以采用枚举 和XML配置 来反射做
			{
				case "0":
					INormal normal = kernel.Get<INormal>();
					sum = normal.TotalSum().ToString();
					break;
				case "9":
					IDiscount discount = kernel.Get<IDiscount>();
					sum = discount.DisCountTotalSum().ToString();
					break;
				case "100":
					IReturn returns = kernel.Get<IReturn>();
					sum = returns.ReturnTotalSum().ToString();
					break;

			}
			return sum.ToString();
		
		}

		// POST api/values
		public void Post([FromBody]string value)
		{
		}

		// PUT api/values/5
		public void Put(int id, [FromBody]string value)
		{
		}

		// DELETE api/values/5
		public void Delete(int id)
		{
		}
