问题 I have a 32 bit .Net 4.0 application running in a wow64 environment in a 64 bit machine. The application encountered an error and I took a dump with 32 bit taskmanager present in C:\Windows\SysWOW64\taskmgr.exe I am using a 32 bit Windebugger to analyze this dump. I loaded the following dlls. 1).loadby sos CLR 2).load mscordacwks ( from the client machine). But still I am not able to use SOS commands like !clrstack,!threads etc. I get the error: Failed to load data access DLL, 0x80004005 What

问题 I am trying to understand the object size difference between 32 bit and 64 bit processors. Let’s say I have a simple class class MyClass { int x; int y; } So on a 32 bit machine, an integer is 4 bytes. If I add the Syncblock into it ( another 4 bytes), the object size will be 12 bytes. Why is it showing 16 bytes? 0:000> !do 0x029d8b98 Name: ConsoleApplication1.Program+MyClass MethodTable: 000e33b0 EEClass: 000e149c Size: 16(0x10) bytes (C:\MyTemp\ConsoleApplication1\ConsoleApplication1\bin

问题 One can dump all the string using the following command !dumpheap -type System.string How can dump or print only those string which starts or contains a specific "string" Example. I am only intrested to view the string which contains "/my/app/request" 回答1: Use sosex instead of sos for this. It has a !strings command which allows you to filter strings using the /m:<filter> option. 回答2: Use !sosex.strings. See !sosex.help for options to filter strings based on content and/or length. 回答3: Not
