asp.net-web-api - 在 asp.net web api 中找到了与请求匹配的多个操作

Question

我正在研究“Code Camper”示例 SPA 应用程序。我在安装了 MVC 4 的 VS 2010 上运行该应用程序。但是我遇到了 LookupsController 的问题。

这是我得到的错误:

    "exceptionMessage":"Multiple actions were found that match the request: \r\nSystem.Collections.Generic.IEnumerable`1[CodeCamper.Model.Room] GetRooms() on type
 CodeCamper.Controllers.LookupsController\r\nSystem.Collections.Generic.IEnumerable`1[CodeC
amper.Model.TimeSlot] GetTimeSlots() on type 
CodeCamper.Controllers.LookupsController","exceptionType":"System.InvalidOperationException
","stackTrace":"   at System.Web.Http.Controllers.ApiControllerActionSelector.ActionSelectorCacheItem.SelectActio
n(HttpControllerContext controllerContext)\r\n   at 
System.Web.Http.Controllers.ApiControllerActionSelector.SelectAction(HttpControllerContext 
controllerContext)\r\n   at 
System.Web.Http.ApiController.ExecuteAsync(HttpControllerContext controllerContext, 
CancellationToken cancellationToken)\r\n   at 
System.Web.Http.Dispatcher.HttpControllerDispatcher.SendAsyncInternal(HttpRequestMessage 
request, CancellationToken cancellationToken)\r\n   at

CancellationToken cancellationToken)"

我找到了答案!

创建web api项目时，默认global.asax.cs中有这行代码

WebApiConfig.Register(GlobalConfiguration.Configuration);

我删除了它(正如我从 codecamper 的源代码中看到的那样)，现在没有问题了!但我不知道为什么
