.NET Forum / .NET Framework / CLR / April 2007debugging dynamic code
Hi. I want to debug in an app written by me (not in vs) in step by step a routine copiled using the microsoft.csharp.compiler. Is there any way to do so? Thanks Cristian Mori Hi MoriCristian, I am not quite sure what you mean here...do you want to debug an assembly that has been compiled to IL where you do not have the associated source code? Debugging IL is possible but certainly not easy and there will be compromises that you have to make because of the way sequence points are generated. Sequence points essentially map between IL instructions and native instructions. Depending on the size of the assembly it may be possible for you to convert the IL code back in to source code using a tool such as .Net reflector. If this is not possible then you could take a look at the managed debugger located here: http://blogs.msdn.com/jmstall/archive/2004/09/30/236281.aspx. It is restricted to #2 of the framework and is really not recommended as a production strength utility. I guess it depends on how desperate you are to get into the assembly. I hope I have understood your problem properly, please let me know if that is not the case. wibbleret Development blog at http://wibberlet.blogspot.com ==================================================== > Hi. > I want to debug in an app written by me (not in vs) in step by step a > routine copiled using the microsoft.csharp.compiler. > Is there any way to do so? > Thanks > Cristian Mori Gi wibbleret, thanks for your reply I need to add dynamic "scripting" in c# to a program I made (this program is also made in c#) I want to open an internal editor from my program, load my source file, compile it and debug it. All this while the other components of my program continue running. I hope I made myself clearer. Do you think you can help me with this issue? Thanks Cristian Mori > Hi MoriCristian, > [quoted text clipped - 28 lines] > > Thanks > > Cristian Mori Hi, You can attach referenced code that you have written to a running process and then debug your code when it is called (assuming you have the source code); your reply here implies that perhaps you do. The process is described here http://msdn2.microsoft.com/en-us/library/c6wf8e4z.aspx You can attach to multiple processes at once if required. I guess it all depends on how you are referencing your dependant assemblies. regards wibbleret Development blog at http://wibberlet.blogspot.com =================================================== > Gi wibbleret, thanks for your reply > I need to add dynamic "scripting" in c# to a program I made (this program is [quoted text clipped - 40 lines] > > > Thanks > > > Cristian Mori the problem is that i do not want to use vs to debug the script. the debugger must be inside my app, so iI need to have a debugger that dubug the dynamic code generate insie my app inside itself. cristian > Hi, > [quoted text clipped - 57 lines] > > > > Thanks > > > > Cristian Mori Hi Cristian, My apologies for not quite understanding your requirements. Given what you are trying to do I think your only chance is to look at something like Cordbg.exe that ships with the framework SDK (including source code I believe). http://msdn2.microsoft.com/en-us/library/a6zb7c8d(vs.80).aspx There is also DbgCLR.exe http://msdn2.microsoft.com/en-us/library/7zxbks7z(VS.80).aspx which may be suitable for what you are trying to do. This provides a graphical UI for debugging services. Other than that you are probably stuck with the VS IDE (and the licensing fee) or a free utility such as SharpDevelop altho this would have to be spawned as a separate process from your application (which is of course what you are trying to avoid). regards wibbleret Development blog at http://wibberlet.blogspot.com ===================================================== > the problem is that i do not want to use vs to debug the script. > the debugger must be inside my app, so iI need to have a debugger that dubug [quoted text clipped - 63 lines] > > > > > Thanks > > > > > Cristian Mori thanks for your reply. I'll take a look at the samples you gave me, maybe i'll find a way. Anyway I want to point that i need to avoid vs not for fee issues, but becaouse in out toolkit we neet to implement a c# script engine and a debugger for those scripts, so vs cannot be used as debugging engine and another way must be found Thanks Cristian Mori > Hi Cristian, > [quoted text clipped - 85 lines] > > > > > > Thanks > > > > > > Cristian Mori Hi Cristian, Based on my understanding, your application is dynamically generating C# code through microsoft.csharp.compiler. Now, you want to employ a debugging function in your own application to debug the generated C# code step by step. If I have misunderstood you, please feel free to tell me, thanks. Based on my knowledge, the CLR debugging feature is exposed through ICorDebug as managed debugging service. So your application may leverage this interface to get debugging feature. The CLR team has implemented a sample C# debugger MDbg with source code available. All the best resource regarding MDbg is maintained here: "MDbg Linkfest" http://blogs.msdn.com/jmstall/archive/2005/11/08/mdbg_linkfest.aspx The CLR developer Mike Stall also created a category regarding MDBG below: http://blogs.msdn.com/jmstall/archive/tags/MDbg/default.aspx Hope this helps.
