浅谈ASP.NET Core 2.0 部分视图(译)

问题

如何在ASP.NET Core 2.0中使用部分视图来重用页面的公共部分？

答案

新建一个空项目，在Startup中添加MVC服务和中间件：

public void ConfigureServices(IServiceCollection services)

{

  services.AddMvc();

}

 

public void Configure(IApplicationBuilder app, IHostingEnvironment env)

{

  if (env.IsDevelopment())

  {

    app.UseDeveloperExceptionPage();

  }

 

  app.UseMvc(routes =>

  {

    routes.MapRoute(

      name: "default",

      template: "{controller=Home}/{action=Index}/{id?}");

  });

}

添加两个模型：

 public class EmployeeViewModel

{

  public int Id { get; set; }

  public string Firstname { get; set; }

  public string Surname { get; set; }

  public AddressViewModel Address { get; set; }

}

 

public class AddressViewModel

{

  public string Line1 { get; set; }

  public string Line2 { get; set; }

  public string Line3 { get; set; }

}

添加控制器，返回ViewResult并传入模型实例：

public class HomeController : Controller

{

  public IActionResult Index()

  {

    var model = new EmployeeViewModel

    {

      Id = 1,

      Firstname = "James",

      Surname = "Bond",

      Address = new AddressViewModel

      {

        Line1 = "Secret Location",

        Line2 = "London",

        Line3 = "UK"

      }

    };

    return View(model);

  }

}

添加视图页面Index.cshtml：

@using PartialView.Models;

@model EmployeeViewModel

 

<div style="border: 1px solid black; margin: 5px">

  <h2>Employee Details (parent view)</h2>

 

  <p>Firstname: @Model.Firstname</p>

  <p>Surname: @Model.Surname</p>

 

  @Html.Partial("_Address.cshtml", Model.Address)

</div>

添加部分视图_Address.cshtml：

@using PartialView.Models

@model AddressViewModel

 

<div style="border: 1px dashed red; margin: 5px">

  <h3>Address Details (partial view)</h3>

 

  <p>Lin1: @Model.Line1</p>

  <p>Line2: @Model.Line2</p>

  <p>Line3: @Model.Line3</p>

</div>

现在，解决方案中的目录结构：
