I was recently working on an application that was known for throwing random exceptions at various times for no apparent reason. Frustrated, I wrote this snippet of code to ease the tension. I just thought I'd share it with you.
Program.cs
using System;
using System.Collections.Generic;
namespace RandomConsoleTests
{
class RandomConsoleTests
{
static void Main(string[] args)
{
ThrowRandomException();
}
public static void ThrowRandomException()
{
throw ExceptionFactory.CreateRandomException();
}
}
}
ExceptionFactory.cs
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Configuration;
using System.Configuration.Provider;
using System.Data;
using System.IO.IsolatedStorage;
using System.Net.Mail;
namespace RandomConsoleTests
{
public static class ExceptionFactory
{
public static Exception CreateRandomException()
{
Random rand = new Random();
switch (rand.Next(0, 20))
{
case 0:
return new ApplicationException();
case 1:
return new ProviderException();
case 2:
return new SettingsPropertyIsReadOnlyException();
case 3:
return new SettingsPropertyNotFoundException();
case 4:
return new SettingsPropertyWrongTypeException();
case 5:
return new IsolatedStorageException();
case 6:
return new SmtpException();
case 7:
return new SystemException();
case 8:
return new AccessViolationException();
case 9:
return new AppDomainUnloadedException();
case 10:
return new ArgumentException();
case 11:
return new ArithmeticException();
case 12:
return new ArrayTypeMismatchException();
case 13:
return new BadImageFormatException();
case 14:
return new CannotUnloadAppDomainException();
case 15:
return new KeyNotFoundException();
case 16:
return new WarningException();
case 17:
return new TimeoutException();
case 18:
return new OutOfMemoryException();
case 19:
return new DataException();
case 20:
return new InvalidOperationException();
default:
return new Exception();
}
}
}
}
