1. 确保在项目中安装了 Microsoft.AspNetCore.OData NuGet 包。
2. 确保在 Startup.cs 中添加了以下配置：

using Microsoft.AspNet.OData.Extensions;
using Microsoft.AspNet.OData.Builder;

// ...

public void ConfigureServices(IServiceCollection services)
{
    // ...
    services.AddMvc(options => {
        options.EnableEndpointRouting = false; // If using ASP.NET Core 3.0 or later
    });

    services.AddOData();
    services.AddSingleton();
}

public void Configure(IApplicationBuilder app)
{
    app.UseMvc(routeBuilder =>
    {
        routeBuilder.Select().Filter().Expand().OrderBy().MaxTop(null).Count();
        routeBuilder.MapODataServiceRoute("odata", "odata", GetEdmModel());
    });
}

private static IEdmModel GetEdmModel()
{
    var builder = new ODataConventionModelBuilder();
    builder.EntitySet("MyEntitySet");
    return builder.GetEdmModel();
}

3. 在控制器类上添加 [EnableQuery] 属性，如下所示：

using Microsoft.AspNet.OData;

// ...

[EnableQuery]
public class MyController : ODataController
{
    // ...
}

4. 确保使用正确的命名空间，如下所示：

using Microsoft.AspNet.OData;
using Microsoft.AspNetCore.Mvc;

// ...

5. 如果使用了 ASP.NET Core 2.x，则需要为控制器启用 OData 功能，如下所示：

using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.OData.Routing.Controllers;

// ...

public class MyController : ODataController
{
    // ...
}
