的OData V4使用2参数

Question

我只想2参数传递到控制器，并运行自己的SQL-功能 尝试和GOOGLE了大量的资源，没有运气，

任何人都可以给我一些提示吗？

我基本上遵循这一Web API and OData- Pass Multiple Parameters

在使用builder.Function编译我一直告诉我没有发现扩展方法。

package.config

Answer 1

您应该使用System.Web.OData.Builder，而不是System.Web.Http.OData.Builder。它应该在包Microsoft.AspNet.OData。

如果.GetEdModel()引发异常，那么您的定义可能有问题，而不是使用。

Answer 2

嗯，我按照这个办法：

WebApiConfig.cs

using System.Web.Http; 
using System.Web.OData.Extensions; 
using System.Web.OData.Builder; 
//using System.Web.OData.Extensions; 
using wcod.Model; 

namespace wcod 
{ 
    public static class WebApiConfig 
    { 
     public static void Register(HttpConfiguration config) 
     { 
      // Web API configuration and services 
      ODataModelBuilder builder = new ODataConventionModelBuilder(); 
      config.Count().Filter().OrderBy().Expand().Select().MaxTop(null); 

      builder.EntitySet<TimeMarker>("TimeMarkers"); 

      var function = builder.Function("GetTimeMarkerSearch"); 
      function.Parameter<string>("bookID"); 
      function.Parameter<string>("keywords"); 
      function.ReturnsCollectionFromEntitySet<TimeMarker>("TimeMarkers"); 
       config.MapHttpAttributeRoutes(); 

      //config.Routes.MapODataServiceRoute("odata", "odata/v4", builder.GetEdmModel()); 

      config.MapODataServiceRoute("odata", "odata/v4", builder.GetEdmModel()); 
     } 

    } 
} 

然后在我的控制， mycase Ti meMarkersControllers

[HttpGet] 
[ODataRoute("GetTimeMarkerSearch(bookID={bookID},keywords={keywords})")] 
public IHttpActionResult WhateverName([FromODataUri]string bookID, [FromODataUri]string keywords){ 
// my logic 
}
