新建 ASP.NET Core MVC 項目，coremvc
一.創建一個空項目
請查看 新建 .NET Core 項目 -- Hello World! 一節,新建一個項目:
二.添加引用並修改配置為 MVC
修改 .vscode\launch.json 文件
代碼如下:
![]()
1 {
2 "version": "0.2.0",
3 "configurations": [
4 {
5 "name": ".NET Core Launch (web)",
6 "type": "coreclr",
7 "request": "launch",
8 "preLaunchTask": "build",
9 "program": "${workspaceRoot}\\bin\\Debug\\netcoreapp1.0\\WebAppCore.dll",
10 "args": [],
11 "cwd": "${workspaceRoot}",
12 "stopAtEntry": false,
13 "internalConsoleOptions": "openOnSessionStart",
14 "env": {
15 "ASPNETCORE_ENVIRONMENT": "Development"
16 },
17 "sourceFileMap": {
18 "/Views": "${workspaceRoot}/Views" // 用來編譯 cshtml
19 }
20 }
21 ]
22 }
launch.json
修改 .vscode\tasks.json 文件
代碼如下:
![]()
1 {
2 "version": "0.1.0",
3 "command": "dotnet",
4 "isShellCommand": true,
5 "args": [],
6 "tasks": [
7 {
8 "taskName": "build",
9 "args": [
10 "${workspaceRoot}\\project.json"
11 ],
12 "isBuildCommand": true,
13 "problemMatcher": "$msCompile"
14 }
15 ]
16 }
tasks.json
修改 project.json 項目文件
代碼如下,注意必要依賴的添加項,微軟新的MVC庫文件:
![]()
1 {
2 "dependencies": {
3 "Microsoft.NETCore.App": { // 多平台編譯,必須在這裡指明 .net core
4 "version": "1.0.1",
5 "type": "platform"
6 },
7 "Microsoft.ApplicationInsights.AspNetCore": "1.0.0",
8 "Microsoft.AspNetCore.Mvc": "1.0.1",
9 "Microsoft.AspNetCore.Razor.Tools": {
10 "version": "1.0.0-preview2-final",
11 "type": "build"
12 },
13 "Microsoft.AspNetCore.Routing": "1.0.1",
14 "Microsoft.AspNetCore.Server.Kestrel": "1.0.1"
15 },
16
17 "tools": {
18 "Microsoft.AspNetCore.Razor.Tools": "1.0.0-preview2-final"
19 },
20 "frameworks": {
21 "netcoreapp1.0": {
22 "imports": [
23 "dotnet5.6"
24 ]
25 }
26 },
27 "buildOptions": {
28 "emitEntryPoint": true,
29 "preserveCompilationContext": true
30 },
31 "runtimeOptions": {
32 "configProperties": {
33 "System.GC.Server": true
34 }
35 }
36 }
project.json
添加 Startup.cs 文件
代碼如下,注意代碼中的 ConfigureServices 與 Configure 方法:
![]()
1 using Microsoft.AspNetCore.Builder;
2 using Microsoft.Extensions.Configuration;
3 using Microsoft.Extensions.DependencyInjection;
4
5
6 namespace WebAppCore
7 {
8 public class Startup
9 {
10 public IConfigurationRoot Configuration { get; }
11
12 public Startup()
13 {
14 Configuration = new ConfigurationBuilder().Build();
15 }
16
17 // 被 runtime 使用的方法.
18 // 用這個方法向 容器 中添加服務.
19 public void ConfigureServices(IServiceCollection services)
20 {
21 services.AddApplicationInsightsTelemetry(Configuration);
22 services.AddMvc();
23
24 }
25
26 // 被 runtime 使用的方法.
27 // 用這個方法配置 Http 請求管道.
28 public void Configure(IApplicationBuilder app)
29 {
30 app.UseMvc(routes =>
31 {
32 routes.MapRoute(
33 name: "default",
34 template: "{controller=HelloWorld}/{action=Index}/{id?}");
35 });
36 }
37 }
38 }
Startup.cs
修改 Program.cs 文件
代碼如下,代碼中建立了 Host :
![]()
1 using System.IO;
2 using Microsoft.AspNetCore.Hosting;
3
4 namespace WebAppCore
5 {
6 public class Program
7 {
8 public static void Main(string[] args)
9 {
10 var host = new WebHostBuilder()
11 .UseKestrel()
12 .UseContentRoot(Directory.GetCurrentDirectory())
13 .UseStartup<Startup>()
14 .Build();
15
16 host.Run();
17 }
18 }
19 }
Program.cs
三.添加 Controller/View
在項目中分別添加以下文件夾
Controllers
Views
Views\HelloWorld
Views\Shared
在 Views 目錄中創建 模板頁及相關文件
Views\Shared\_Layout.cshtml
Views\_ViewImports.cshtml
Views\_ViewStart.cshtml
代碼如下,注意布局頁的使用:
![]()
1 <!DOCTYPE html>
2
3 <html>
4 <head>
5 <meta charset="utf-8" />
6 <meta name="viewport" content="width=device-width, initial-scale=1.0" />
7 <title>@ViewData["Title"]</title>
8 </head>
9 <body>
10 <div class="container body-content">
11 @RenderBody()
12 </div>
13 </body>
14 </html>
_Layout.cshtml
![]()
1 @addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers
_ViewImports.cshtml
![]()
1 @{
2 Layout = "_Layout";
3 }
_ViewStart.cshtml
添加控制器 Controllers\HelloWorldController.cs
添加與控制器對應的視圖 Views\HelloWorld\Index.cshtml
相應代碼如下:
![]()
1 using Microsoft.AspNetCore.Mvc;
2
3 namespace WebAppCore.Controllers
4 {
5 public class HelloWorldController : Controller
6 {
7 public IActionResult Index()
8 {
9 //
10 return View();
11 }
12 }
13 }
HelloWorldController.cs
![]()
1 @{
2 ViewData["Title"] = "Index";
3 Layout = "~/Views/Shared/_Layout.cshtml";
4 }
5
6 <h2>Hello World!</h2>
Index.cshtml
四.使用Visual Studio Code 運行
