英文:
Get C# file fields and properties using regular expression
问题
我想要使用正则表达式匹配（从.cs文件中选择）属性名称、字段名称以及它们被使用的位置。
这是一个示例类：
using System;... // 使用的命名空间using Grpc.Net.Client;using UI = Gtk.Builder.ObjectAttribute;namespace DummyProject;public class MainWindow : Window{[UI] private readonly MenuItem _aboutMenuItem;[UI] private readonly MenuItem _openFolderItem;[UI] private readonly MenuItem _openFileItem;[UI] private readonly Viewport _fileViewport;[UI] private readonly Notebook _codeNotebook;private readonly SourceView _codeSourceView;private readonly FileViewer _fileViewer;private readonly Files.FilesClient _filesClient;public FileSystemViewer FileSystemViewer { get; }public MainWindow(){_fileViewer = new FileViewer();// 一些代码}// 方法
结果将是：_aboutMenuItem, _openFolderItem, _openFileItem, _fileViewport, _codeNotebook, _codeSourceView, _fileViewer, _filesClient, FileSystemViewer
我尝试了以下正则表达式：^(?:(?=[^()]*$))?(?:(?!.*\b(namespace|return|using|class)\b))[\t \b]*(?:[\[\]a-zA-Z0-9_.]+\s+)?(?:(?:private|public|protected|internal)\s+)?(?:(?:static readonly|static|const|readonly|volatile|virtual|override)\s+)?(?:(?:[a-zA-Z0-9\.]+)\s+)?(\w+)\s*
但是这个正则表达式匹配错误（请参见https://regex101.com/r/ZbctGa/3）
有什么建议吗？
英文:
I want to match (select from .cs file) property names, field names and places where they are used using regular expression.
This is example class:
using System;... // usingsusing Grpc.Net.Client;using UI = Gtk.Builder.ObjectAttribute;namespace DummyProject;public class MainWindow : Window{[UI] private readonly MenuItem _aboutMenuItem;[UI] private readonly MenuItem _openFolderItem;[UI] private readonly MenuItem _openFileItem;[UI] private readonly Viewport _fileViewport;[UI] private readonly Notebook _codeNotebook;private readonly SourceView _codeSourceView;private readonly FileViewer _fileViewer;private readonly Files.FilesClient _filesClient;public FileSystemViewer FileSystemViewer { get; }public MainWindow(){_fileViewer = new FileViewer();// some code}// methods
Result will be: _aboutMenuItem, _openFolderItem, _openFileItem, _fileViewport, _codeNotebook, _codeSourceView, _fileViewer, _filesClient, FileSystemViewer
I've tried this regular expression: ^(?:(?=[^()]*$))?(?:(?!.*\b(namespace|return|using|class)\b))[\t \b]*(?:[\[\]a-zA-Z0-9_.]+\s+)?(?:(?:private|public|protected|internal)\s+)?(?:(?:static readonly|static|const|readonly|volatile|virtual|override)\s+)?(?:(?:[a-zA-Z0-9\.]+)\s+)?(\w+)\s*
But this regex matches incorrectly (see https://regex101.com/r/ZbctGa/3)
Any suggestions?

得分: 1
以下是翻译好的部分：
_aboutMenuItem_openFolderItem_openFileItem_fileViewport_codeNotebook_codeSourceView_fileViewer_filesClientFileSystemViewer
英文:
You can use the following to capture the properties and fields.
(?:public|private)(?! class) (?:readonly )?(?:.+?) (.+?)[ ;]
Output
_aboutMenuItem_openFolderItem_openFileItem_fileViewport_codeNotebook_codeSourceView_fileViewer_filesClientFileSystemViewer
