VS Code：如何阻止注释状态代码自动展开及折叠注释代码？

Hey there! I totally get how frustrating it is when commented code in VS Code keeps auto-expanding without your permission. Let's break down the solutions step by step, based on common scenarios you might be facing.

1. Disable Auto-Expansion When Commenting Folded Code #

If you notice that every time you comment a folded block of code, it automatically unfolds—this is a default VS Code behavior that's easy to turn off:

• Open the Settings panel with Ctrl+, (Windows/Linux) or Cmd+, (Mac)
• In the search bar, type editor.unfoldOnComment
• Toggle the switch from true to false

From now on, commenting folded code won't trigger an auto-unfold. Problem solved for that scenario!

2. Make Comment Blocks Foldable (and Keep Them Folded) #

If your commented code isn't folding at all, or keeps popping open, adjust these settings and use manual controls:

Enable Comment Folding by Default #

First, ensure VS Code recognizes comment blocks as foldable:

• In Settings, search editor.foldingStrategy and confirm it's set to auto (this is the default, but double-check if you've modified it before)
• Search editor.autoFoldComments:
  • Set to true if you want comment blocks to auto-fold when you open a file
  • Set to false if you prefer to fold them manually as needed

Manually Fold/Unfold Comment Blocks #

Even with default settings, you can take control manually:

• Fold a comment block: Place your cursor anywhere in the comment, then press Ctrl+Shift+[ (Windows/Linux) or Cmd+Shift+[ (Mac)
• Unfold it: Use Ctrl+Shift+] (Windows/Linux) or Cmd+Shift+] (Mac)

Custom Foldable Comment Regions (For Tricky Cases) #

If VS Code doesn't automatically recognize a large comment block as foldable, use manual region markers to force it:

// #region Commented Code Block
/* 
This is a long comment section
that you want to keep folded
without auto-expansion
*/
// #endregion

These markers work across most languages and let you fully control which comment blocks are foldable.

3. Lock Folded Comment Blocks (Prevent Accidental Unfolding) #

If you want to make sure a folded comment block stays folded no matter what (even if you edit nearby code), use the lock feature:

• Right-click the small fold arrow (next to the line numbers on the left side of the editor)
• Select Lock Folding—the arrow will turn gray, and the block won't auto-unfold
• To unlock it later, right-click the arrow again and choose Unlock Folding
