如何从Visual Studio 2013调试.NET控制台应用程序

Question

I've created a .NET 4.5 console application (an .exe file) with c# that processes some data in various files. The whole thing runs in less than one second. I have a problem with a testing version of the .exe that I'd like to step through in the Visual Studio 2013 debugger using particular input files (the filenames are passed as command line arguments). I can't do an "Attach to process..." since the process has completed too quickly to attach to it. How do I debug in this case.

Note that I'm from the python world, and the python equivalent of what I'm trying to do is python -m pdb pdb_script.py .

Thanks for any advice!

Answer 1

Right click on your project and go to "properties".

Then select the "debugging" tab on the left-hand side.

There's a box where you can input the desired command line arguments for use when running in debug mode.

EDIT: If you're asking how to start the debugger, then add some breakpoints to your code, then right click on the project in your solution and pick Debug > Start New Instance.

Alternatively you can right click and choose "Set as Startup Project", after which you can start debugging with F5 or the "Start" button at the top of the UI.

Answer 2

Add the following line in your code:

System.Diagnostics.Debugger.Break();

This will allow you to debug your application before it ends.

Answer 3

In Visual Studio, you can add commandline arguments before starting a debugging session by right-clicking your project, selecting properties and then going down to the debug tab.

Then you can start it in Visual Studio with f5

If that's too much trouble (because you are going to change the arguments a lot), you could do something like adding a Console.ReadLine to your program at the beginning that will give you a change to attach a debugger. You could even have an extra command line argument for debugging that will only pause for you to attach the debugger if you pass that argument.
