How to make C# application crash

Question

I want to test if my application crash dump can be debugged. But firstly, I need to generate a crash dump of my application. I\'m using C# to code my app, and have tried wit

Answer 1

The following will provide an unhandled exception and will ask for you to choose a debugger:

System.Diagnostics.Debugger.Launch()

Answer 2

 int[] x = {0};
 int blah = x[2];

will cause an exception just as well

Answer 3

It's easy enough to reproduce if you try to transform a null game object. For example, like this:

public static GameObject gameObjectCrash;
public void GenerateCrash()
{
    gameObjectCrash.transform.rotation = Quaternion.Euler(90, 0, 0);
}

Answer 4

Use below code to close the application.

Environment.Exit(1);    

Exit needs a parameter called exitcode. If exitcode=0 means there was no error. Supply a non-zero exit code to to reflect an error.

Answer 5

Throw an exception :)

throw new Exception("Your exception here!");

Answer 6

Well. The only good 100% way actualy crash CLR is to inject a native exception into the managed world.

Calling the Kernel32.dll's RaiseException() directly will immediately crash ANY C# application, and Unity Editor as well.

[DllImport("kernel32.dll")]
static extern void RaiseException(uint dwExceptionCode, uint dwExceptionFlags,  uint nNumberOfArguments, IntPtr lpArguments);

void start()
{
    RaiseException(13, 0, 0, new IntPtr(1));
}

Happy crashing. Please note that in order to debug native and managed, you will need two instances of Visual Studio running. If you are developing native P/INVOKE plugin, set up it that Visual Studio Instance 1 is native debugger and uses Unity or your C# program as a Host program, and you attach to the Host program from another Visual Studio Instance.
