Visual Studio Profiler显示DLL名称而不是函数名称

我正在关注分析教程： http ： //msdn.microsoft.com/en-us/magazine/cc337887.aspx

我试图通过使用CPU采样来分析项目。

MSDN结果：

我的结果：

我期待看到System.Drawing.Bitmap.SetPixel而不是[System.Drawing.ni.dll] 。

根据这篇文章的建议，我有：

• 单击“显示所有代码”链接
• 禁用“只是我的代码”
• 在工具>选项>调试>符号中选中“Microsoft Symbol Serves”，重新启动visual studio并再次运行报告。

输出（按照上述步骤后）：

解压缩后，它将位于名为VSTSProfiler的文件夹中。 无论如何，这是粘贴的源代码，以防它下降:)

Answer 1

发现如何：

• 从您正在编译的相同版本的.NET运行NGEN.exe版本。 示例： C:\Windows\Microsoft.NET\Framework64\v4.0.30319
• 给它参数createpdb
• 指定PDB所需的DLL的完整路径指定程序集缓存的路径。 示例： ngen.exe createpdb C:\windows\pathtoassembly.dll C:\SymbolCache

有效的最终命令。 我重新加载了Visual Studio，之后又成功了。 我使用了相同的链接Hans Passant顺便发布。
