使用 2 个参数的 ode vc

Question

我只想将 2 个参数传递给控制器和运行我的 sql-函数尝试用谷歌搜索很多资源，但没有成功，

谁能给我一些提示？

基本上我遵循这个Web API and OData- Pass Multiple Parameters

当我使用 builder.Function 编译器时，一直告诉我找不到扩展方法。

好吧，我遵循这种方法：

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());
        }

    }
}

然后在我的控制器中，mycase TimeMarkersControllers

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

Answer 2

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.

中

如果 .GetEdModel() 抛出异常，则可能是您的定义有问题，而不是使用问题。
