解析C#中的命令行参数/选项 [英] Parse command line arguments/options in C#

问题描述

我有一个带有一些参数和选项的控制台应用程序，所以我想使用免费的第三方库.

I have a console application with some arguments and options so I would like to use a free third-party library.

我为此找到了两个库: NDesk.Options 和

I have found two libraries for this purpose: NDesk.Options and Command Line Parser Library

最后，我决定使用命令行分析器库，因为使用属性可以使它更清晰，因此我下载了该库并添加了对它的引用.

Finally I have decided to use Command Line Parser Library because it is clearer using properties so I have downloaded it and added a reference to it.

问题是，当将引用添加到我的.NET Framework 3.5项目时，我得到一个警告图标.从上面下载了它的页面上，它说兼容性是.NET Framework 3.5+，所以我知道3.5是兼容的，对吗?如果不是，它的哪个早期版本与.NET Framework 3.5兼容?

The problem is that when adding the reference to my .NET Framework 3.5 project I get a warning icon. From the above page where I have downloaded it, it says that compatibility is .NET Framework 3.5+ so I understand 3.5 is compatible, am I right? If not which previous version of it is compatible with .NET Framework 3.5?

推荐答案

您还可以使用新的 Microsoft CommandLineUtils 库. nuget软件包在这里，但仅适用于.NET Core或Framrwork 4.5.2. 但是您可以下载源代码(仅7个文件)并包含在您的projet中.对于Framework 3.5，您只有2个编译错误要解决:删除一个额外的方法(使用Tasks)和删除一行(在HandleUnexpectedArg中).

You can also use the new Microsoft CommandLineUtils library. The nuget package is here, but only for .NET Core or Framrwork 4.5.2. But you can download the source code (only 7 files) and include in your projet. For the Framework 3.5, you have only 2 compilation errors to solve: remove an extra method (using Tasks) and remove one line (in HandleUnexpectedArg).

• Nuget: https://www.nuget.org/packages/Microsoft.Extensions .CommandLineUtils
• 来源: https://github.com /aspnet/Common/tree/dev/shared/Microsoft.Extensions.CommandLineUtils.Sources

• Nuget: https://www.nuget.org/packages/Microsoft.Extensions.CommandLineUtils
• Source: https://github.com/aspnet/Common/tree/dev/shared/Microsoft.Extensions.CommandLineUtils.Sources

要使用此库，请在此处找到第一个示例:

To use this library, find here a first sample:

static void Main(string[] args)
{
    var cmd = new CommandLineApplication();
    var argAdd = cmd.Option("-a | --add <value>", "Add a new item", CommandOptionType.SingleValue);

    cmd.OnExecute(() =>
    {
        Console.WriteLine(argAdd.Value());
        return 0;
    });

    cmd.HelpOption("-? | -h | --help");
    cmd.Execute(args);            
}
