描述
I have used the old version of the CommandlineParser and it worked fine.
Now I have upgraded my console app to the latest Nuget, run the app and receive:
`System.InvalidOperationException: 'Zero is not allowed in range of sequence option specifications.'`
I have detected that option 't' is the reason of the exception.
How to fix it?
There is my definition
```
class Options
{
[Option('i', "input", Required = true, HelpText = "Input folder/file to be processed.")]
public string InputFolder { get; set; }
[Option('x', "xfiles", Required = false, HelpText = "Exclude files to be processed.")]
public IEnumerable ExcludeFiles { get; set; }
[Option('t', "types", Required = false, Min =0, Max=6,HelpText = "Exclude file extensions to be processed.")]
public IEnumerable ExcludeFileExtensions { get; set; }
[Value(0)]
public int Offset { get; set; } = 0;
}
```

研究方向
使用提供的 Options 類別重現例外,重點關注 [Option('t', "types", Min = 0, Max = 6)] 宣告及其 IEnumerable 屬性。未指定原始檔案或測試,因此請追蹤選項驗證進入點,並判斷哪種行為或定義應視為已修正。
