使用SOS-在VisualStudio中启用非托管代码调试来支持本机代码调试..doc

?? SOS(Son of Strike)扩展调试器可以用来显示CLR数据结构的内容。SOS是作为.net framework的一部分安装的(SOS.dll)，位于%windir%\Microsoft.NET\Framework\v*.*.****(版 本号)\目录下。在使用SOS(加载SOS.dll)进行调试的步骤：Step1 在Visual Studio中设置项目属性,以启动托管调试:Visual Studio打开要调试的项目，菜单-项目(Project)-Project属性-调试-启用非托管代码调试，如下图所示： Step2 在代码中设置断点-F5启动调试，运行到断点处； Step3 设置Symbol目录：??? 如果不设置Symbol目录，运行下面的命令时会提示“PDB symbol for mscorwks.dll not loaded”，这里我们只需要再设置下Symbol目录就行了：菜单-工具-选项-调试-符号，设置如下： Step4 菜单-调试(Debug)-窗口(Windows)-即时(Immediate)，在打开的“即时窗口”中输入“!load sos.dll”来加载SOS.dll，如果加载成功，则会提示“已加载扩展%windir%\Microsoft.NET\Framework \v*.*.****(版本号)\sos.dll”； Step5 在“即时窗口”中输入“!help”可以获得调试命令列表(如下)，输入!help command 可以获得该命令的详细信息. !help-------------------------------------------------------------------------------SOS?is?a?debugger?extension?DLL?designed?to?aid?in?the?debugging?of?managedprograms.?Functions?are?listed?by?category,?then?roughly?in?order?ofimportance.?Shortcut?names?for?popular?functions?are?listed?in?parenthesis.Type?!help?functionname?for?detailed?info?on?that?function.?Object?Inspection??????????????????Examining?code?and?stacks-----------------------------??????-----------------------------DumpObj?(do)???????????????????????ThreadsDumpArray?(da)?????????????????????CLRStackDumpStackObjects?(dso)?????????????IP2MDDumpHeap???????????????????????????UDumpVC?????????????????????????????DumpStackGCRoot?????????????????????????????EEStackObjSize????????????????????????????GCInfoFinalizeQueue??????????????????????EHInfoPrintException?(pe)????????????????COMStateTraverseHeap???????????????????????BPMD?Examining?CLR?data?structures??????Diagnostic?Utilities-----------------------------??????-----------------------------DumpDomain?????????????????????????VerifyHeapEEHeap?????????????????????????????DumpLogName2EE????????????????????????????FindAppDomainSyncBlk????????????????????????????SaveModuleDumpMT?????????????????????????????GCHandlesDumpClass??????????????????????????GCHandleLeaksDumpMD?????????????????
