Csharp C#System.Commandline：如何向命令添加参数以便向其传递值

下面的简单Program.cs要求已定义的根命令只有一个参数:

using System.CommandLine;

var inputArgument = new Argument<string>(
  name: "--input", 
  description: "input any value and print it out");

var rootCommand = new RootCommand();
rootCommand.AddArgument(inputArgument);
rootCommand.SetHandler((inputArgumentValue) =>
{
  Console.WriteLine($"{inputArgumentValue}");
}, inputArgument);

rootCommand.Invoke(args);

我希望使用以下参数调用它:--input "Hello World"以在shell 中打印出Hello World.但是，我得到以下错误:

Unrecognized command or argument 'Hello World'.个

当我将Argument类替换为Option类时，它按预期工作:

using System.CommandLine;

var inputArgument = new Option<string>(
  name: "--input", 
  description: "input any value and print it out");

var rootCommand = new RootCommand();
rootCommand.AddOption(inputArgument);
rootCommand.SetHandler((inputArgumentValue) =>
{
  Console.WriteLine($"{inputArgumentValue}");
}, inputArgument);

rootCommand.Invoke(args);

What did I misunderstand about the 100 class? Why can I not pass an argument with a value to it?

由于它的其他属性，我想使用参数类而不是选项.我使用的是.NET 6.0和System.CommandLine版本2.0.0-beta4.22272.1
