Have you ever worship those knock a few lines of code to create the god of the project, learning the commands to create a project you can also become a great God, in fact, very simple command to create the project.

1.cmd command line you intend to create a project location

 

 

 

2. Create the directory solution folder JIYUWU_ONE, then you use the command to create a solution with the following command:

mkdir JIYUWU_ONE
cd JIYUWU_ONE
dotnet new sln

 

Note: The name of the default solution is the name of the current directory. 

3. Create a Web project, the following command:

dotnet new mvc -o JIYUWU_ONE.Web

As shown below:

 

4. Create a Common Class Library project, the command is as follows:

dotnet new classlib -o JIYUWU_ONE.Common

As shown below:

 

5. If you want to JIYUWU_ONE.Common class library project JIYUWU_ONE.Common.csproj added to the solution file, use the following command:

dotnet sln JIYUWU_ONE.sln add JIYUWU_ONE.Common/JIYUWU_ONE.Common.csproj

JIYUWU_ONE.Web project, too, use the following command:

dotnet sln JIYUWU_ONE.sln add JIYUWU_ONE.Web/JIYUWU_ONE.Web.csproj

As shown below:

 

6 . Add a reference to JIYUWU_ONE.Common.csproj projects in JIYUWU_ONE.Web.csproj project, use the following command:

dotnet add JIYUWU_ONE.Web/JIYUWU_ONE.Web.csproj reference JIYUWU_ONE.Common/JIYUWU_ONE.Common.csproj

如下图所示：

 

7.在解决方案下每个项目中执行命令：

dotnet restore

如果在某个项目下执行dotnet restore那么则restore的是某个项目，如下图所示：

 

8.在命令行中执行命令(VS Code安装参考我的上一篇文章)：

code .

则使用Visual Studio Code打开该项目，如下图所示：

 

 

 注意：中间有个空格。

9.我们在Visual Studio Code中找到类库项目，添加一个新类One,并添加一个返回字符串的静态方法

using System;

 

namespace JIYUWU_ONE.Common

{

    public class One

    {

        public static string HelloBody()

        {

            return "认识你真好，缘来你也想学.Net Core呀！";

        }

    }

}

如下图所示：

 

10.我们在MVC项目的HomeController中，在Privacy方法中添加对类库项目方法的调用

public IActionResult Privacy()

        {

            string msg=JIYUWU_ONE.Common.One.HelloBody();

            ViewData["Msg"]=msg;

            return View();

        }

如下图所示：

 

11.修改Privacy.cshtml试图页面

@{

    ViewData["Title"] = "Privacy Policy";

}

<h1>@ViewData["Title"]</h1>

<p>@ViewData["Msg"]</p>

如下图所示：

 

12.我们回到命令行输入:

dotnet build 

编译整个项目，如下图所示：

 

13.命令行输入:

dotnet publish

发布项目

 

14.命令行输入:

cd JIYUWU_ONE.Web/bin/Debug/netcoreapp3.0/publish

将目录切换到MVC项目目录，然后在命令行中输入:

dotnet JIYUWU_ONE.Web.dll

来运行项目如图：

 

15.地址栏输入：https://localhost:5001/Home/Privacy可以看到效果如下图：

 

16.由于它是不受信任的，我们给它弄个证书吧，执行命令：

dotnet dev-certs https –trust

 

 再次运行看效果

 

 

 

都看到最后了，帮助到你了就动动小手，点个推荐吧！
