Visual Studio 2017编辑器换行仅一个Tab，需恢复为两个的问题咨询

Hey Robert, I’ve run into this exact indentation quirk before in VS2017—let’s get it sorted out quickly. Here are the steps to restore your 2-tab auto-indent when pressing Enter:

1. Check Global Text Editor Settings (Applies to Most Languages) #

• Open the Tools menu at the top, then select Options (or press Ctrl+Q, type "Options", and hit Enter to jump straight there).
• In the Options window, expand the Text Editor node, then select General.
• Scroll down to the Indentation section:
  • Make sure Auto indent is checked (this enables automatic indentation when you press Enter).
  • If you prefer actual Tab characters over spaces, ensure Insert tabs is selected (instead of "Insert spaces").

2. Verify Language-Specific Indentation Settings (Critical!) #

VS lets you override indent settings per language, so this is likely where the unexpected change happened:

• Still in the Options window, expand Text Editor again, then select the language you’re working with (e.g., C#, C++, HTML, etc.).
• Choose the Tabs sub-node under that language.
• Configure these settings:
  • Select Keep tabs to ensure actual Tab characters are inserted (not spaces).
  • Set Tab size to your preferred width for a single Tab (e.g., 4 characters—this controls how wide each Tab appears, not the number of Tabs inserted).
  • Set Indent size to 2—this tells VS to insert 2 Tab characters whenever you press Enter to wrap a line.
  • Confirm Smart indent is selected under "Indent style" (this ensures indentation matches your code’s context).

3. Reset Settings (If All Else Fails) #

If the above steps don’t fix the issue, corrupted settings might be the culprit:

• Go to Tools > Import and Export Settings.
• Select Reset all settings, then follow the prompts to reset to default settings (you can back up your current settings first to preserve other customizations).
• After resetting, revisit the Tabs settings for your language and reconfigure the 2-tab indent as needed.

That should bring back the 2-tab auto-indent you’re used to. Let me know if you hit any snags!
