我試圖從VS單元測試工具運行它時剖析我的.NET DLL，但是我遇到問題。我正在使用獨立的命令行分析器，因爲VS2008 Professional不附帶內置的分析器。在VS2008 Professional中使用MS獨立分析器
我有一個開放的CMD窗口，並運行以下命令（我儀表早前這就是爲什麼vsinstr給了警告，它沒有）：
C:\...\BusinessRules\obj\Debug>vsperfclrenv /samplegclife /tracegclife /globalsamplegclife /globaltracegclife
Enabling VSPerf Sampling Attach Profiling. Allows to 'attaching' to managed applications.
Current Profiling Environment variables are:
COR_ENABLE_PROFILING=1
COR_PROFILER={0a56a683-003a-41a1-a0ac-0f94c4913c48}
COR_LINE_PROFILING=1
COR_GC_PROFILING=2
C:\...\BusinessRules\obj\Debug>vsinstr BusinessRules.dll
Microsoft (R) VSInstr Post-Link Instrumentation 9.0.30729 x86

Error VSP1018 : VSInstr does not support processing binaries that are already instrumented.
C:\...\BusinessRules\obj\Debug>vsperfcmd /start:trace /output:foo.vsp

然後我跑了單元測試，行使儀表碼。當單元測試是完全的，我沒有...
C:\...\BusinessRules\obj\Debug>vsperfcmd /shutdown

這顯然是在等待VS2008封閉，因此我關閉了它......
Shutting down the Profile Monitor

C:\...\BusinessRules\obj\Debug>
所有看起來不錯，有一個3.2MB目錄中的foo.vsp文件。我接下來做了...
C:\...\BusinessRules\obj\Debug>vsperfreport foo.vsp /summary:all

注意關於環境變量和使用vsperfclrenv的警告？但我已經跑了！也許我使用了錯誤的開關？我不知道。無論如何，加載CSV文件導入Excel或使用perfconsole工具提供有用的信息負載無用的符號名：

我如此接近能夠找到瓶頸，如果只有它會給我的功能和模塊名稱而不是十六進制數字！
我在做什麼錯？
