[英]How to create executable console app from .NET Core 2.0 in Linux?
As far as I know in the https://www.microsoft.com/net/learn/get-started/macos , we only able to run it: 据我所知,在https://www.microsoft.com/net/learn/get-started/macos中 ,我们只能运行它:
$ dotnet run
I have a requirement to create a console app that we execute from a terminal as below: 我需要创建一个我们从终端执行的控制台应用程序,如下所示:
$ ./my_console_app file_inputs.txt
How to create an executable that can run in a terminal like that? 如何创建可以在这样的终端中运行的可执行文件?
In order to create a standalone console app in Linux, you should use a self-contained deployment (SCD) publishing mode for your dotnet core app: 要在Linux中创建独立控制台应用程序,您应该为您的dotnet核心应用程序使用自包含部署(SCD)发布模式:
This will generate a single binary that bundles the target framework and can be executed independently without any extra shell-scripts or pre-installed dotnet runtime. 这将生成捆绑目标框架的单个二进制文件,并且可以独立执行,无需任何额外的shell脚本或预先安装的dotnet运行时。
I recommend to use the official dotnet cli console
template and then publish your project as a --self-contained
switch by specifying your target runtime (eg: linux-x64
) and framework what you use. 我建议使用官方dotnet cli console
模板,然后通过指定目标运行时 (例如: linux-x64
)和框架将您的项目作为--self-contained
开关发布。
So start with the basic console
template: 所以从基本的console
模板开始:
dotnet new console -o myconsoleapp
cd myconsoleapp
Edit program.cs
to process your input-file or other arguments based on your business logic, eg: nano program.cs
and add something like: 编辑program.cs
以根据您的业务逻辑处理您的输入文件或其他参数,例如: nano program.cs
并添加如下内容:
using System;
namespace myconsoleapp
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Hello Linux!");
if (args.Length > 0) { Console.WriteLine("Input is: " + args[0]); }
}
}
}
Test your application with dotnet run file_inputs.txt
and it should print to the console correctly. 使用dotnet run file_inputs.txt
测试您的应用程序,它应该正确打印到控制台。
In order to get the binaries and the bundled framework to be distributed, you should run dotnet publish
: 为了分发二进制文件和捆绑框架,你应该运行dotnet publish
:
dotnet publish -c release --self-contained --runtime linux-x64 --framework netcoreapp2.0
You can then distribute your publish folder
and then execute your app just simply by: 然后,您可以通过以下方式分发您的publish folder
,然后执行您的应用:
./myconsoleapp file_inputs.txt
Here's a bit more detailed article about creating standalone Linux console app in dotnet core: 这里有一篇关于在dotnet核心中创建独立Linux控制台应用程序的更详细的文章:

page: 此处还可以在publish
页面上阅读有关其他可用Linux模板的更多信息:
Finally, I'm able to find the answer and solve this by my self. 最后,我能够找到答案并通过我自己来解决这个问题。 I created a shell script and made it executable. 我创建了一个shell脚本并使其可执行。
$ touch my_console_app
$ chmod 777 my_console_app
I put this command to that newly created my_console_app file and saved it. 我把这个命令放到新创建的my_console_app文件中并保存。
dotnet run --project ./path/to/your/project.csproj "$1"
Now I can run and execute my .net core project using this executable shell script and able to accept a parameter argument. 现在我可以使用这个可执行的shell脚本运行并执行我的.net核心项目,并且能够接受参数参数。
$ ./my_console_app file_inputs.txt
EDIT: 编辑:
If you only have the .dll file from .net core project you can change the content of my_console_app into: 如果您只有.net核心项目的.dll文件,则可以将my_console_app的内容更改为:
dotnet ./path/to/your/project.dll "$1"
