.net core 中的局部视图组件是ViewComponent,可以用于建制重复使用公共功能组件
一、新建一个类DemoViewComponent(必须以ViewComponent结尾)且继承ViewComponent
using Microsoft.AspNetCore.Mvc; using NetCoreApiDemo.Model; using System; using System.Collections.Generic; using System.Linq; using System.Threading; using System.Threading.Tasks; namespace NetCorePortal.Components { public class DemoViewComponent : ViewComponent { public async Task<IViewComponentResult> InvokeAsync() { List<tbl_page> pageList = new List<tbl_page>(); for (int i = 0; i < 10; i++) { pageList.Add(new tbl_page() { page_no = i.ToString(), page_name = i.ToString() }); } return View(pageList);//此处没有返回ViewName 对应的视图文件是Default.cshtml //return View("D", pageList);//此处返回的ViewName 是“D” 对应的视图文件是D.cshtml } } }
二、在View/Share目录下建立Components目录,并在此目录下建立Demo目录及对应Default.cshtml文件
@model IEnumerable<NetCoreApiDemo.Model.tbl_page> <h1>Demo IViewComponentResult</h1> <table> <tr> <th>page_no</th> <th>page_name</th> </tr> @foreach (var item in Model) { <tr> <td>@item.page_no</td> <td>@item.page_name</td> </tr> } </table>
