I have an ASP.NET web app which is small yet has a fair amount of C# behind it.
I am trying to run some code, which is dependent on a class library/.dll I have produced (containing business logic). When I debug, after I bind to datasource property, I get an object reference not set to an instance object.
I know how to fix these errors as I have done more than my fair show when I lacked experience, but the trouble I have is I cannot find the last method to execute (which will in turn help me find the variable at fault) until this exception. Is there a way I can make the code break when it reaches the line of code causing this exception (or the line of code matching the last method called in the stacktrace)? I will probably do a find for that method signature but I don’t really like this approach. Is this something for windbg?
I guess this is what they mean by unmaintainable code.
Look at the stack trace that is most likely printed out with the error.
Also try breaking on exceptions – Debug Menu -> Exceptions, Choose CLR Exceptions
