四、HelloWorld项目
- 1、创建项目
#使用命令提示符(cmd)或者Windows PowerShell
#1、打开项目文件夹(如果没有就先创建好)
d:
cd d:\projects
#2、创建项目
dotnet new console -o helloworld
#dotnet new :创建&初始化项目
#console : 模板类型(相当于VS创建项目选择控制台应用程序)
#-o :指定output路径名,可以理解为项目文件夹名称,默认项目名称=项目文件夹名称,也可以用-n 单独指定项目名称
#dotnet new console -n helloworld 效果等同于 dotnet new console -o helloworld
#执行输出:
The template "Console Application" was created successfully.

Running 'dotnet restore' on helloworld\helloworld.csproj...

#项目文件就在d:\projects\hellworld中
- 2、输出结果分析
#1、显示根据指定dotnet new console -o helloworld模板创建了项目
The template "Console Application" was created successfully.
#2、然后又主动调用了dotnet restore命令来还原项目的引用,主动安装依赖

- 3、运行
cd d:\projects\helloworld
dotnet run
#运行结果
Hello World!
# 恭喜你,你的第一个.NET Core应用程序就这么诞生了
#源代码请查 d:\projects\hellworld\Program.cs 文件
五、备注
- 支持的项目模板
#使用命令提示符(cmd)或者Windows PowerShell
#1、打开项目文件夹(如果没有就先创建好)
d:
cd d:\projects
#2、创建项目
dotnet new console -o helloworld
#dotnet new :创建&初始化项目
#console : 模板类型(相当于VS创建项目选择控制台应用程序)
#-o :指定output路径名,可以理解为项目文件夹名称,默认项目名称=项目文件夹名称,也可以用-n 单独指定项目名称
#dotnet new console -n helloworld 效果等同于 dotnet new console -o helloworld
