Asp.net使用分页的核心OData似乎无法找到如何获得总记录计数

回复如下:

访问此链接 https://www.odata.org/getting-started/basic-tutorial/#count 我的朋友。

这是一个样品。希望能帮上忙,朋友:)

安装程序包Microsoft.AspNetCore.OData-版本7.1.0

--模型--

public class Product
    {
        public int ID { get; set; }
        public string Name { get; set; }
    }

public class ProductsController : ODataController
    {
        private List<Product> products = new List<Product>()
        {
            new Product()
            {
                ID = 1,
                Name = "Bread",
            },
            new Product()
            {
                ID = 2,
                Name = "Tomato",
            },
            new Product()
            {
                ID = 3,
                Name = "Lemon",
            },new Product()
            {
                ID = 4,
                Name = "Orange",
            }
        };

        [EnableQuery]
        public List<Product> Get()
        {
            return products;
        }
    }

--启动---

public void ConfigureServices(IServiceCollection services)
        {
            services.AddMvc(option => 
            {
                option.EnableEndpointRouting = false;
            }).SetCompatibilityVersion(CompatibilityVersion.Version_2_2);            
            services.AddOData();
        }

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }
            else
            {
                // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
                app.UseHsts();
            }            

            var builder = new ODataConventionModelBuilder(app.ApplicationServices);

            builder.EntitySet<Product>("Products");

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

        }
