Hey man...The .NET Framework SDK includes the command-line runtime debugger
named CorDbg.exe, which some developers might prefer over its Windows-based
counterparts, DbgClr and the debugger that is built into Visual Studio. As with
DbgClr, CorDbg does not compile applications. To use these compilers, it is
first necessary to build the application so that it includes the appropriate
/debug switch.
The run-time debugger allows you to perform the following tasks. Start,
attach to, continue, detach from, and stop a running process. Display
application domains, assemblies, loaded modules, classes, and global functions.
Step into and over both source and native instructions. Show
source-code lines. Set the value of a variable. Set the next
statement to a new line. Set or display breakpoints.
The full list of CorDbg options can be displayed by typing CorDbg /? from a
command prompt.
for example., if you wanna debug "Sample.exe", From a command prompt, you can
start the debugger with this program by typing CorDbg Sample.exe from the
directory that contains the executable file. This action starts CorDbg and
displays the following lines.(cordbg) run sample.exe Process 1596/0x63c
created. [thread 0x624] Thread created. 234: using (Form f = new
VersioningDemo()){ //automatically calls Dispose()Now execute the
"pro(cessenum)" instruction:
(cordbg) pro
PID=0x49c (1596) Name=C:\...\Sample\CS\sample.exe
ID=1 AppDomainName=sample.exe*
PID=0x544 (1348) Name=C:\...\aspnet_wp.exe
ID=3 AppDomainName=/LM/w3svc/1/Root/NetSDK/Debug-2-...
ID=2 AppDomainName=/LM/w3svc/1/Root/NetSDK-1-...
ID=1 AppDomainName=DefaultDomain
This shows that Sample.exe has a ProcessID of 1596. This computer is also
executing an ASP.NET application with a ProcessID of 1348. If you are not
running debug versions of the .NET runtime, you will likely not have the
symbols installed for the runtime libraries, and you will also see a series of
warnings saying those symbols cannot be loaded. Now, execute the "sh(ow)"
instruction to show the source code:(cordbg) sh 229: } 230: }
231: 232: [System.STAThreadAttribute()] 233: public static void
Main(string[] args) { 234* Form f = new VersioningDemo(); 235:
f.ShowDialog(); 236: //throw(new System.Exception()); //a
runtime error 237: } 238: } 239: }
This tells us that execution is currently halted in line 234, which is the
first line in the program. At this point, you might want to try executing the
following commands: ap � Displays information about the application domain.
l � Lists the currently loaded modules, classes, and global functions.
p � Prints the current variables. sh 50 � Shows the 50 preceding
source-code lines.
