使用正则匹配所有中文,但特定行除外

使用下面的正则表达式,可以匹配出所有的中文,但是我想把注释行排除,正则表达式应该怎样更改? 我知道排除//的表达式是(?!//),但是添加进去都没有效果,望高手指点
期望的输出结果:
文字一
文字二
文字三
文字四

$s= @'
class Program
{
    static void Main()
    {
        //这里的文字不处理
        ComponentInfo.SetLicense("FREE-LIMITED-KEY");

        DocumentModel document = new DocumentModel();

        Section section = new Section(document);
        document.Sections.Add(section);

        Paragraph paragraph = new Paragraph(document);
        section.Blocks.Add(paragraph);

        Run run = new Run(document, "文字一"); 
        paragraph.文字二Inlines.Add(run);文字三

        文字四document.Save("test.docx");
    }
}
'@

[regex]::Matches($s, '[^x00-xff]+') | foreach { $_.value } | echo
