【问题描述】：
我在从 VS 单元测试工具运行时尝试分析我的 .NET dll，但我遇到了问题。我使用的是独立的命令行分析器，因为 VS2008 Professional 没有内置分析器。
我有一个打开的 CMD 窗口并运行了以下命令（我之前对其进行了检测，这就是 vsinstr 发出警告的原因）：
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
Microsoft (R) VSPerf Command Version 9.0.30729 x86

C:\...\BusinessRules\obj\Debug>
然后，我运行单元测试来执行已检测的代码。当单元测试完成后，我做了......
C:\...\BusinessRules\obj\Debug>vsperfcmd /shutdown
Microsoft (R) VSPerf Command Version 9.0.30729 x86

显然是在等待 VS2008 关闭所以我关闭了它...

C:\...\BusinessRules\obj\Debug>
看起来不错，目录中有一个 3.2mb 的 foo.vsp 文件。接下来我做了...
C:\...\BusinessRules\obj\Debug>vsperfreport foo.vsp /summary:all

注意到关于环境变量和使用 vsperfclrenv 的警告了吗？但我已经运行它了！也许我使用了错误的开关？我不知道。无论如何，将 csv 文件加载到 Excel 或使用 perfconsole 工具会提供大量有用的信息和无用的符号名称：

只要它能给我函数和模块名称而不是十六进制数字，我就可以找到瓶颈了！
我做错了什么？
