Web Api Request.CreateResponse HttpResponseMessage no intellisense VS2012
提问by crizzwald
For some reason, Request.CreateResponseis now "red" in VS2012 and when I hover over the usage the IDE says
出于某种原因，Request.CreateResponse现在在 VS2012 中为“红色”，当我将鼠标悬停在使用上时，IDE 说
Cannot resolve symbol 'CreateResponse'
无法解析符号“CreateResponse”
Here is the ApiController Class:
这是 ApiController 类：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web.Http;
using System.Web.Http.Filters;
using GOCApi.Attributes;
using GOCApi.Models;
using GOCApi.Models.Abstract;
using AttributeRouting;
using AttributeRouting.Web.Http;
namespace GOCApi.Controllers
{
[RoutePrefix("Courses")]
public class CoursesController : ApiController
{
private ICoursesRepository _coursesRepository { get; set; }
public CoursesController(ICoursesRepository coursesRepository)
{
_coursesRepository = coursesRepository;
}
[GET("{id}")]
public HttpResponseMessage Get(int id)
{
var course = _coursesRepository.GetSingle(id);
if (course == null)
return Request.CreateResponse(HttpStatusCode.NotFound, "Invalid ID");
return Request.CreateResponse(HttpStatusCode.OK, course);
}
}
}
Granted, the code does compile and works, it's just really annoying seeing all the "red" on my screen. Also, the intellisense doesn't work now when I type Request.CreateResponse. This also used to work, but I started developing other parts to my API and just came back to building controllers so I do not know what happened.
当然，代码确实可以编译并运行，但看到屏幕上所有的“红色”真的很烦人。此外，当我输入Request.CreateResponse. 这也曾经有效，但我开始为我的 API 开发其他部分，然后又回到构建控制器，所以我不知道发生了什么。
Any thoughts?
有什么想法吗？

Because this extension method lives in System.Net.Http, you just need to include it in your usings statements.
由于此扩展方法存在于 中System.Net.Http，因此您只需要将其包含在 using 语句中。
using System.Net.Http;

You need to add a reference to System.Net.Http.Formatting.dll. The CreateResponseextension method is defined there.
您需要添加对System.Net.Http.Formatting.dll. 该CreateResponse扩展方法被定义在那里。

This is because you have to do:
这是因为你必须这样做：
namespace GOCApi.Controllers
{
[RoutePrefix("Courses")]
public class CoursesController : ApiController
{
private ICoursesRepository _coursesRepository { get; set; }
public CoursesController(ICoursesRepository coursesRepository)
{
_coursesRepository = coursesRepository;
}
[GET("{id}")]
public HttpResponseMessage Get(int id)
{
var course = _coursesRepository.GetSingle(id);
if (course == null){
return this.Request.CreateResponse(HttpStatusCode.NotFound, "Invalid ID");
}
return this.Request.CreateResponse(HttpStatusCode.OK, course);
}
}
}
Note the this.
In my case the compiler now gets it.
Saw the example here
请注意this.
在我的情况下，编译器现在得到了它。看到这里的例子

You can use
您可以使用
HttpResponseMessage result = new HttpResponseMessage(HttpStatusCode.Gone)
instead of
代替
Request.CreateResponse(HttpStatusCode.Gone)

Add a reference to System.Web.Httpto the project. Then add
添加System.Web.Http对项目的引用。然后加
Using System.Web
to the top of the cs file.
到 cs 文件的顶部。
