ReSharper 的静态分析器似乎已损坏.我如何解决它? [英] ReSharper's static analyzer appears to be corrupted. How do I fix it?

问题描述

我遇到了 ReSharper 提供明显错误建议的问题.例如，在以下代码示例中，ReSharper 表示从不使用 response、dates 和 ex 变量用于以下几行:

I'm having a problem with ReSharper giving obviously wrong advice. For example, in the following code sample, ReSharper is saying that the response, dates, and ex variables are never used, when they are clearly used on the following lines:

Dim response As New WcfResponseBoolean
Try
    ' ReSharper identifies 'b' as unused, but it is used on the next line.
    b = Builders.CastBuilderFromSession

    If b Is Nothing Then
    response.SetSessionExpired()
        Return response
    End If

    ' ReSharper identifies 'dates' as unused, but it is used on the next line.
    Dim dates As New List(Of DateTime)({ConvertToUSDateTime(inWithTime)})

    CompareDateList(response, inTimeToCompare, New ComparableDatesList() 
        With {.Dates = dates, .CheckCompareType = compareType}, False)

' ReSharper identifies 'ex' as unused, but it is used on the next line.
Catch ex As Exception
    MailHandler.SendExceptionEmailToBTDebug(ex, "CompareDates")
    response.SetUnhandledException()
End Try

我已按照 此链接中的建议 尝试清除 ReSharper 的通过转到 ReSharper --> 选项 --> 环境 --> 常规并单击清除缓存"按钮来缓存.但是当我点击那个按钮时，我没有从 ReSharper 那里得到任何关于发生任何事情的反馈.屏幕就在那里；没有弹出消息，没有任何类型的 UI 反馈.当我单击保存"按钮关闭表单时，问题仍然存在.

I've followed the advice from this link to try clearing ReSharper's caches by going to ReSharper --> Options --> Environment --> General and clicking the "Clear Caches" button. But when I click that button, I get no feedback from ReSharper that anything happened. The screen just sits there; no popup message, no UI feedback of any kind. And when I click the Save button to close the form, the problem persists.

TL;DR:
有没有其他方法可以清除 ReSharper 的缓存?否则，是否有其他方法可以让静态分析器再次工作?

我在 Visual Studio 2012(版本 11.0.61030.0)中运行 ReSharper 8.1.23.546.

更新 1:

我还尝试清理和重建项目，以及关闭和打开 Visual Studio.这些都没有任何影响.从这里我能想到的唯一两件事是:

I've also tried cleaning and rebuilding the project, and closing and opening Visual Studio. Neither of these have had any effect. The only two things I can think to do from here are:

1. 手动删除 ReSharper 的缓存文件.但我不知道它们位于何处，而且我不确定这样做是否安全.
2. 卸载并重新安装 ReSharper.但这似乎很激烈.我宁愿不这样做，除非这是唯一的选择.

更新 2:

我使用 citizenmatt's answer 来定位和删除缓存文件，但没有任何区别.ReSharper 仍在将变量标识为未使用.

I used citizenmatt's answer to locate and delete the cache files, but it didn't make any difference. ReSharper is still identifying the variables as unused.

我还重新启动了我的电脑，但我还没有这样做，但正如我所料，这并没有真正改变任何东西.我可能会认为卸载和重新安装是唯一的选择.

I also rebooted my PC, which I had not done yet, but as I expected that didn't really change anything. I may be getting to the point that uninstalling and reinstalling is the only option left.

更新 3:

我吃完午饭回来，决定硬着头皮卸载并重新安装.这也没有解决这个问题.现在我越来越绝望了.

I came back from lunch and decided to bite the bullet and do an uninstall and reinstall. That did not fix this issue either. Now I'm getting desperate.

推荐答案

您可以在 %LOCALAPPDATA%\JetBrains\ReSharper\v8.1\SolutionCaches 找到解决方案缓存.缓存文件夹名为_ReSharper.{Solution}.{hash}，其中{solution}是解决方案的名称，hash是一个数值，防止名称冲突.您应该能够找到您要找的那个.在关闭 Visual Studio 的情况下将其删除并重新打开解决方案.

You can find the solution caches at %LOCALAPPDATA%\JetBrains\ReSharper\v8.1\SolutionCaches. The cache folder is named _ReSharper.{Solution}.{hash}, where {solution} is the name of the solution, and the hash is a numeric value to prevent name clashes. You should be able to find the one you're looking for. Delete it with Visual Studio closed and reopen the solution.
