我怎样才能让用户类型的 C # 语法突显在 vs2012RC 中重新工作？

不知何故，我对 C # 代码的部分语法突显在2012年版本的 IDE 中消失了。卸载、重新启动和重新安装都不起作用，重新设置选项对话框中的颜色也不起作用。

下面是一些项目的例子，这些项目都默认显示(黑色) ，通常有颜色，但没有:

  • 属性
  • 系统类
  • 我自己的课

下面是一些仍然有颜色的关键词:

  • 使用
  • 公众人士
  • 无效
  • Var
  • 为了

还有其他人经历过这种情况，并设法修复它吗？

I had the same issue....just uninstalling and re-installing alone did not correct the problem. After I un-installed, deleted all remnants of VS 2012 in program files, removed all related registry keys, and deleted the VS 2012 folder from My Documents, then re-installed, user types showed up in the display items in fonts and colors and everything went back to normal. My guess is that it was an issue with one or more of the registry keys but I can't be sure of that.

Here is a simple solution. Go to the directory where devenv is (for 2012 RC), and type devenv.exe /setup. It will fix your problem.

devenv.exe is usually in something like C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE.

Edit: It has been suggested that you do this from the Visual Studio command prompt (Start>Microsoft Visual Studio>Tools>Visual Studio Command Prompt), and/or make sure your command prompt has administrator permissions.

Note for others: This has a very good chance of working for many other versions of Visual Studio, including 2008, 2010, 11 beta, ...

If none of the above work for you, delete all GUID-named folders under this registry key (make sure your Visual Studio instance is closed):

If you're using Visual Studio 2012: HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\11.0\FontAndColors

If you're using Visual Studio 2013: HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\12.0\FontAndColors

If you're using Visual Studio 2015: HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\14.0\FontAndColors

Restart Visual Studio, and you should see a few various "User Types" to configure. You can then import your Fonts and Colors that you backed-up, and everything will be good to go. This may also work for previous and future versions of VS, but I have not tested.

Disclaimer: Make sure you export/backup your current Fonts and Colors settings before making these registry adjustments. I cannot be held responsible for you losing your configs :)

exit devenv

go to below path hkey_current_user\software\microsoft\visualstudio!

remove 9.0 , 10.0 , 10.0_config (i mean to say all other folders except 11.0 and 11.0_config)

Now start devenv and see the magical colors get back normal

If you still have this issue try ResetSettings (worked for me)

NOTE: this will reset the Visual Studio 2012 settings :)

1) close vs.

2)open cmd (as administrator).

3) go to devnev.exe folder (something like "C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE" ).

4) type "devnev.exe /ResetSettings"

5) open vs and look at the beautiful colors

This is what worked for me:

1 - delete all in C:\Users\userNAme\AppData\Roaming\Microsoft\VisualStudio\11.0
2 - open vs console as administrator, and run:
devenv.exe /setup
devenv.exe /ResetSettings

This will reset all your environment settings.

My problem was limited to having the "DateTime" type not showing up in light blue like other class names. I fixed it by simply switching back-and-forth between VS Themes. Discovered by accident. Much quicker than reset settings or repair install...

VS menu Tools -> Change Color Theme

For me "Productivity Power Tools 2012" was the cause. Nothing suggested here helped. After removing the Power Tools the colors came back.

小开

Found the source of the problem: If you have the "Productivity Power Tools 2012" installed,

you should go to Tools -> Options -> Productivity Power Tools and turn off the "Colorized Parameter Help" option.

This fixed the syntax highlight problem.

If anybody runs in to the same problem for Visual Studio 2013 as I did, the only solution that worked for me was to first close VS2013 and then delete the following registry key:

HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\12.0\FontAndColors

After reopening VS2013, my syntax highlighting for types was restored.

Prior to deleting the registry key, I noticed that all of the "User Types..." settings in the Fonts and Colors section of Tools > Options were missing. Deleting the registry key restored them. They attained their default values which gave me the syntax highlighting colors I was looking for.

This was the only solution that worked for me. Switching themes, resetting my personalized settings to defaults, running devenv.exe with various command line switches to setup/reset Visual Studio did not work.

I also created the following bug report with Microsoft on their Connect site:

http://connect.microsoft.com/VisualStudio/feedback/details/810985/incorrect-syntax-highlighting-for-c-types.

If you've installed the preview of Roslyn, unintstall it. This worked for me.

After trying several of the solutions listed here, I eventually found that my issue was caused by a very large (488000+ characters) string variable. Highlighting was working up to that line, but not after it. Once I reduced the length of the string, highlighting in the rest of the file resumed working normally.

I did all the things listed here and still nothing (VS2013 Update 3). I tried /setup, /resetsettings, deleting the stuff in AppData, deleting the registry keys. Still, User Types wouldn't be highlighted even in the default color scheme.

What helped in the end was opening the Fonts and Colors dialog, selecting Identifier, and making it Bold. Then removing the Bold. Instant fixage!

I already had VS 2012 Pro installed on my machine. I then installed VS 2013 Pro and started facing this color issue. I then deleted the HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\12.0\FontAndColors key and opened VS 2013. This approach solved my issue and the colors were back.

If the windows desktop is configured with a high contrast theme the syntax coloring seems to disappear completely from Visual Studio. If this is the case, select a normal windows theme and set a solid background color (if you don't want a background pictures) to restore syntax coloring in VS.
