Mono - Debug.Assert does not work

Question

I have this program here:

namespace TodoPlus {
using System.Diagnostics;

    public class LameProg {
        public LameProg() {}
        public static void Mai         


        

Answer 1

1. Debug.Assert is annotated with [ConditionalAttribute("DEBUG")]. This means that all invocations are removed by the compiler unless the DEBUG preprocessor symbol is defined. Try this:

   $ dmcs -d:DEBUG LameProg.cs
   

2. Mono does not show a dialog box like Microsoft's .NET implementation when an assertion is hit. You need to set a TraceListener, e.g.

   $ export MONO_TRACE_LISTENER=Console.Error
   $ mono LameProg.exe

Debug.Assert invocations are typically used in debug builds and removed from release builds. If you want to make sure that a certain condition holds, and this check should be present in release builds, use an if statement and throw an exception:

public static void Main(string[] args)
{
    int a = 2;
    int b = 3;
    if (a != b)
    {
        throw new Exception("Bleh");
    }
    System.Console.WriteLine("Haha it didn't work");
}
