Visual Studio: references in code not recognized?
提问by Chris
I have a solution in VS2008 (C#) that contains multiple projects. I just retooled some of the .csproj files for our build process, and suddenly while coding Project B won't recognize references from Project A in the class code...think the red squiggly lines under a variable type I've created. However, building the solution generates no errors. Why's it behaving like this?
我在 VS2008 (C#) 中有一个包含多个项目的解决方案。我刚刚为我们的构建过程重组了一些 .csproj 文件，突然间，在编码项目 B 时无法识别类代码中项目 A 的引用......想想我创建的变量类型下的红色波浪线。但是，构建解决方案不会产生错误。为什么会有这样的行为？

I would suggest that you clear your Visual Studio temp files - it can often get confused about project structures and require a fresh start.
我建议您清除 Visual Studio 临时文件 - 它经常会对项目结构感到困惑，需要重新开始。
First, quit out of VS completely and restart it. If the problem is still there, find your VS cache folder and delete it, and then do a rebuild.
首先，完全退出VS并重新启动它。如果问题仍然存在，请找到您的VS缓存文件夹并将其删除，然后进行重建。
For help finding your cache folder, check this post.

In your Project Properties from B, make sure Project A is checked under dependencies.
在 B 的项目属性中，确保在依赖项下选中项目 A。

When VS starts acting strangely wonky, and I can't find a logical fix, I kill Visual Studio, and manually do a 'clean' by deleting all of the bin/obj folders.
当 VS 开始表现得很奇怪并且我找不到逻辑修复时，我会杀死 Visual Studio，并通过删除所有 bin/obj 文件夹手动执行“清理”。
I have a batch file that does this for me quicker than I could do it manually. I place this in my solution directory, and all my projects are found in subdirectories.
我有一个批处理文件，它比我手动完成的速度更快。我把它放在我的解决方案目录中，我所有的项目都在子目录中。
rem "%%~dpa" says: Give me the (d)drive and (p)path of the (a, %%a) file.
rem However, our dir /a:d will result in only listing folders...
rem The final "%%a" is just appending the 'file' (diretory name) to the
rem drive-and-path string
for /f %%a in ('dir /b /a:d *.*') do call :process "%%~dpa%%a"
pause
goto :eof
:process
echo Looking in %1
cd "%1"
if EXIST "%1\bin" (
echo Found 'bin' - it's gone now.
rd /s /q "%1\bin"
)
if EXIST "%1\obj" (
echo Found 'obj' - it's gone now.
rd /s /q "%1\obj"
)
cd ..

Make sure both projects are being built in the Configuration Manager
确保两个项目都在配置管理器中构建
(right click on the solution and then click “Configuration Manager”)
（右键单击解决方案，然后单击“配置管理器”）
You might also hover over the redline or just build again to see if you get anymore details. C# and VB are both pretty good at telling you why they not happy.
您也可以将鼠标悬停在红线上或重新构建以查看是否获得更多详细信息。C# 和 VB 都非常擅长告诉你为什么他们不开心。

I've removed the reference from the project which classes were not recognized and re-added this reference. Everything got fixed.
我已经从项目中删除了无法识别类的引用，并重新添加了这个引用。一切都搞定了。
