Throwing Exceptions

Exceptions can be thrown either by the runtime or in user code. Here, Display throws a System.ArgumentNullException:

static void Display (string name) { if (name == null) throw new ArgumentNullException ("name"); Console.WriteLine (name); }

Rethrowing an exception

You can capture and rethrow an exception as follows:

try { ... } catch (Exception ex) { // Log error ... throw; // Rethrow same exception }

Rethrowing in this manner lets you log an error without swallowing it. It also lets you back out of handling an exception should circumstances turn out to be outside what you expected.
