Question

In Java, the throws keyword allows for a method to declare that it will not handle an exception on its own, but rather throw it to the calling method.

Is there a similar keyword/attribute in C#?

If there is no equivalent, how can you accomplish the same (or a similar) effect?

Answer 1

In Java, you must either handle an exception or mark the method as one that may throw it using the throws keyword.

C# does not have this keyword or an equivalent one, as in C#, if you don’t handle an exception, it will bubble up, until caught or if not caught it will terminate the program.

If you want to handle it then re-throw you can do the following:

try
{
  // code that throws an exception
}
catch(ArgumentNullException ex)
{
  // code that handles the exception
  throw;
}
