小白使用visual studio code——创建c#项目

1、打开vscode

2、shift+ctrl+`

3、创建名称为MyVscodeApp的解决方案：

[zeo@doris ~]$ pwd
/home/zeo
[zeo@doris ~]$ ls
Desktop  Documents  Downloads  Music  MyApp  Pictures  Public  Templates  Videos  VirtualBox VMs  vmware
[zeo@doris ~]$ dotnet new sln -o MyVscodeApp
The template "Solution File" was created successfully.
[zeo@doris ~]$ ls
Desktop    Downloads  MyApp        Pictures  Templates  VirtualBox VMs
Documents  Music      MyVscodeApp  Public    Videos     vmware

4、创建项目库，名称MyVscodeApp.Model

[zeo@doris ~]$ dotnet new classlib -o MyVscodeApp.Model
The template "Class library" was created successfully.

Processing post-creation actions...
Running 'dotnet restore' on MyVscodeApp.Model/MyVscodeApp.Model.csproj...
  Restore completed in 302.47 ms for /home/zeo/MyVscodeApp.Model/MyVscodeApp.Model.csproj.

Restore succeeded.

[zeo@doris ~]$ 

5、创建控制台项目，名称为MyVscodeApp.HelloWorld

[zeo@doris ~]$ dotnet new console -o MyVscodeApp.HelloWorld
The template "Console Application" was created successfully.

Processing post-creation actions...
Running 'dotnet restore' on MyVscodeApp.HelloWorld/MyVscodeApp.HelloWorld.csproj...
  Restore completed in 309.55 ms for /home/zeo/MyVscodeApp.HelloWorld/MyVscodeApp.HelloWorld.csproj.

Restore succeeded.

[zeo@doris ~]$ 

6、将刚才新建的两个项目添加到当前解决方案中

(1)先将它们移动到解决方案的目录下

[zeo@doris ~]$ ls
Desktop    Downloads  MyApp        MyVscodeApp.HelloWorld  Pictures  Templates  VirtualBox VMs
Documents  Music      MyVscodeApp  MyVscodeApp.Model       Public    Videos     vmware
[zeo@doris ~]$ ls MyVscodeApp
MyVscodeApp.sln
[zeo@doris ~]$ mv MyVscodeApp.HelloWorld MyVscodeApp
[zeo@doris ~]$ mv MyVscodeApp.Model MyVscodeApp
[zeo@doris ~]$ ls
Desktop  Documents  Downloads  Music  MyApp  MyVscodeApp  Pictures  Public  Templates  Videos  VirtualBox VMs  vmware
[zeo@doris ~]$ ls MyVscodeApp
MyVscodeApp.HelloWorld  MyVscodeApp.Model  MyVscodeApp.sln
[zeo@doris ~]$ 

（2）添加到解决方案中

[zeo@doris ~]$ ls MyVscodeApp
MyVscodeApp.HelloWorld  MyVscodeApp.Model  MyVscodeApp.sln
[zeo@doris ~]$ cd MyVscodeApp
[zeo@doris MyVscodeApp]$ ls
MyVscodeApp.HelloWorld  MyVscodeApp.Model  MyVscodeApp.sln
[zeo@doris MyVscodeApp]$ dotnet sln add ./MyVscodeApp.HelloWorld/MyVscodeApp.HelloWorld.csproj
Project `MyVscodeApp.HelloWorld/MyVscodeApp.HelloWorld.csproj` added to the solution.
[zeo@doris MyVscodeApp]$ dotnet sln add ./MyVscodeApp.Model/MyVscodeApp.Model.csproj
Project `MyVscodeApp.Model/MyVscodeApp.Model.csproj` added to the solution.
[zeo@doris MyVscodeApp]$ 

7、类库Model被控制台HelloWorld项目引用

[zeo@doris MyVscodeApp.HelloWorld]$ dotnet add reference  ../MyVscodeApp.Model/MyVscodeApp.Model.csproj
Reference `..\MyVscodeApp.Model\MyVscodeApp.Model.csproj` added to the project.
[zeo@doris MyVscodeApp.HelloWorld]$ 

8、编译

[zeo@doris MyVscodeApp.HelloWorld]$ dotnet build
Microsoft (R) Build Engine version 16.2.32702+c4012a063 for .NET Core
Copyright (C) Microsoft Corporation. All rights reserved.

  Restore completed in 316.74 ms for /home/zeo/MyVscodeApp/MyVscodeApp.Model/MyVscodeApp.Model.csproj.

  MyVscodeApp.HelloWorld -> /home/zeo/MyVscodeApp/MyVscodeApp.HelloWorld/bin/Debug/netcoreapp2.2/MyVscodeApp.HelloWorld.dll

Build succeeded.
    0 Warning(s)
    0 Error(s)

Time Elapsed 00:00:04.45
[zeo@doris MyVscodeApp.HelloWorld]$ 

9、运行

[zeo@doris MyVscodeApp]$ dotnet run --project MyVscodeApp.HelloWorld
Hello World!
[zeo@doris MyVscodeApp]$ 

10、 添加代码，进行测试

（1）在MyVscodeApp.Model中添加Student.cs

（2）修改HelloWolrd项目中的Program.cs

（3）编译、运行

[zeo@doris MyVscodeApp]$ dotnet build
Microsoft (R) Build Engine version 16.2.32702+c4012a063 for .NET Core

遗留问题：

（1）安装的智能提示插件不起作用

（2）自定格式对齐快捷键不起作用

（3）新创建的cs文件开头没有自动添加“using system;”引用

（4）使用菜单快捷键编译运行
