I’m interested in making a program that will take c# code and allow me to step through the execution of that code line by line – a debugger.
How would I go about this project without having to write a whole c# compiler? I’m using Microsoft Visual Studio, but I want my software to be as independent of their debugger implementation as possible.
You’re looking for ICorDebug, the managed debugging API.
You can use
csc.exeto compile the code (this is included in a standard .Net Framework installation and wrapped by the CSharpCodeProvider class), then execute the assembly, attach the debugger, and step through the code.Note that you would probably still need a C# parser to figure out where you are in the source.
The PDB file will contain some of this information; I’m not sure how much.
Note that most of the features in VS’s debugger which we take for granted (especially the Watch window and variable tooltips) will require painful re-implementation. (Func-evals)
