A focused VS Code extension for searching Type, Method, Member, and Impl C# symbols from a dedicated Activity Bar view.

Preview

Tree View List View

Features

  • Dedicated Activity Bar entry: C# Search.
  • Tab-based symbol search:
    • Type: class / interface / struct / enum / record.
    • Method: methods and constructors.
    • Member: fields and properties.
    • Impl: implementations by interface/base type.
  • Switchable result view: Tree / List (single toolbar toggle button).
  • Single-click Expand/Collapse All in result view toolbar.
  • Click a result to open file and jump to line.
  • Focus search view shortcut: Ctrl+T (Cmd+T on macOS), same as Visual Studio.
  • Incremental in-memory index with file watcher updates.

Search Behavior

  • The extension activates when the C# Search panel is opened for the first time.
  • Triggering the focus command (Ctrl+T / Cmd+T) also opens the panel and activates the extension if it is not active yet.
  • Indexing starts only when the opened workspace is detected as a .NET project.
  • In non-.NET workspaces, the view shows an unsupported-workspace hint and does not start indexing.
  • During initial indexing, the search view shows indexing status/progress.
  • Excludes bin, obj, .git, .github, .vscode by default.
  • Updates cache incrementally on create/change/delete events.
  • Supports Fuzzy / Exact mode switching, with case-insensitive matching, and returns up to the configured csharpSearch.maxResults (default 500).
  • Search results are loaded by pages while scrolling; each page size is controlled by csharpSearch.pageSize (default 100).
  • In Impl, search supports implementation type names and interface/base type names.
  • Input placeholder text updates by active tab to indicate expected query intent.

Understanding Search Results

  • Two display modes are available in the toolbar:
    • Tree: folder → file (.cs) → matched line content.
    • List: file (.cs) groups → matched line content.
  • In both modes:
    • Last-level entries show matched full line preview with query highlight.
    • File/group rows show result count badges.
    • Expand/collapse states are supported and can be toggled globally via toolbar.
  • Clicking any last-level match opens the source file and jumps to the exact line.
  • Result meta shows loaded count and total count while more pages are available.
  • A single query returns up to csharpSearch.maxResults items (default 500); if more matches exist, only the first N are kept.

Configuration

csharpSearch.excludeFolders

  • Type: string[]
  • Default: ['bin', 'obj', '.git', '.github', '.vscode']
  • Description: Folder names excluded from indexing (matches at any path depth).

csharpSearch.searchDebounceMs

  • Type: number
  • Default: 300
  • Range: 0-1000
  • Description: Debounce delay (ms) before sending search request while typing.

csharpSearch.pageSize

  • Type: number
  • Default: 100
  • Range: 20-500
  • Description: Number of results loaded per page while scrolling.

csharpSearch.maxResults

  • Type: number
  • Default: 500
  • Range: 50-1000
  • Description: Maximum number of results returned per query.

Development

  • Install dependencies: npm install
  • Build: npm run compile
  • Watch mode: npm run watch
  • Debug extension: press F5

一个专注于 C# 符号检索的 VS Code 扩展,支持 类型、方法、成员、实现 四类检索,并提供独立的活动栏搜索视图。

预览

树形视图 列表视图

功能特性

  • 活动栏独立入口:C# Search。
  • 按类别检索符号:
    • 类型:class / interface / struct / enum / record。
    • 方法:方法与构造函数。
    • 成员:字段与属性。
    • 实现:按接口/基类检索实现或派生类型。
  • 支持结果视图切换:树形 / 列表(顶部单按钮切换)。
  • 支持结果区一键“全部展开 / 全部折叠”。
  • 点击结果可打开文件并定位到行。
  • 聚焦搜索视图快捷键:Ctrl+T(macOS 为 Cmd+T),与 Visual Studio 一致。
  • 内存增量索引 + 文件监听更新。

搜索逻辑

  • 首次打开 C# Search 面板时激活扩展。
  • 触发聚焦命令(Ctrl+T / Cmd+T)也会打开该面板;若扩展尚未激活,将在此时激活。
  • 仅当判定当前工作区为 .NET 项目时,才会启动索引构建。
  • 非 .NET 工作区会显示“当前工作区不是 .NET 项目,未启动索引”,且不会触发索引构建。
  • 首次索引期间,搜索视图会展示索引状态/进度。
  • 默认排除 bin、obj、.git、.github、.vscode。
  • 文件新增/修改/删除后增量刷新缓存。
  • 支持“模糊匹配 / 精确匹配”切换,匹配大小写不敏感,单次最多返回 csharpSearch.maxResults 配置的条数(默认 500)。
  • 搜索结果支持滚动分页加载,每页条数由 csharpSearch.pageSize 控制(默认 100)。
  • 在“实现”标签下,可按实现类名、接口名或基类名检索。
  • 输入框提示会根据当前标签动态切换,降低误搜成本。

搜索结果说明

  • 顶部工具栏支持两种结果视图:
    • 树形:目录 → 文件(.cs)→ 命中行内容。
    • 列表:文件(.cs)分组 → 命中行内容。
  • 两种视图下:
    • 最后一层均显示命中的整行代码预览,并保留关键字高亮。
    • 文件/分组层显示命中数量徽标。
    • 支持节点展开/折叠,并可通过工具栏进行全局展开/折叠。
  • 点击任意最后一层命中项,会打开源文件并跳转到对应行。
  • 结果区在存在更多分页时会显示“已加载/总数”。
  • 单次查询最多返回 csharpSearch.maxResults 配置的条数(默认 500);若实际命中更多,仅保留前 N 条。
