c# - 如何在ASP .NET应用程序上的OData和.NET Core 3.0中启用计数？

当我发出请求时： http：// localhost：5000 / api / v1 / users？$ count = true

它返回对象及其属性值，但不返回用户数：

这是我在控制器中的操作：

   /// <summary>
    /// Gets the list of all available users in the system
    /// </summary>
    /// <returns></returns>
    [HttpGet]
    [EnableQuery]
    public IEnumerable<UserDto> Get()
    {
        var users = dbContext.Users.ToList();

        return users.Select(u =>
        {
            var dto = mapper.Map<UserDto>(u);
            var claims = dbContext.UserClaims.Where(c => c.UserId == u.Id);
            dto.FirstName = claims.FirstOrDefault(c => c.ClaimType == JwtClaimTypes.GivenName)?.ClaimValue;
            dto.FamilyName = claims.FirstOrDefault(c => c.ClaimType == JwtClaimTypes.FamilyName)?.ClaimValue;
            return dto;
        }).ToList();
    }

这是我的启动配置：

services.AddOData();

app.UseMvc(router =>
        {
            router.EnableDependencyInjection();
            router.Select().Expand().Filter().OrderBy().MaxTop(100).Count().EnableContinueOnErrorHeader();
            router.MapODataServiceRoute("odata", "odata", GetEdmModel());
        });

    IEdmModel GetEdmModel()
    {
        var odataBuilder = new ODataConventionModelBuilder();
        odataBuilder.EntitySet<IntentUser>("Users");
        return odataBuilder.GetEdmModel();
    }
