格式化选区:Ctrl+K, Ctrl+F

格式化文档:Ctrl+K, Ctrl+D

查看预定义的键盘快捷键。(这两个是编辑。FormatSelection和Edit.FormatDocument。)

macOS的注意事项

在macOS上，使用CMD⌘键而不是Ctrl键:

格式化选定内容:CMD⌘+K, CMD⌘+F 格式化文档: CMD⌘+ k, CMD⌘+ d

遵循以下步骤:

转到菜单工具 进入选项 转到文本编辑器选项 单击您选择的语言。我以c#为例。

请看下图:

在Visual Studio 2019中，“代码清理”(RunDefaultCodeCleanup)更高级(取自ReSharper): Ctrl + K, Ctrl + E

选项对话框:文本编辑器→c#→代码样式→格式化

在Visual Studio中自动格式化设置

你可以通过工具→选项→环境→键盘来定义新的键绑定:
