finally

Is the working of the following two pieces of code equivalent(concerning the code that's executed no matter an exception is thrown or not)? Or is there a difference other than pure syntactical dispute?

C#: 
namespace Tests
{
	using System;

	public class tryApp
	{
		private static void Main()
		{
			try
			{
				// some code that could throw an exception
			}
			catch
			{
				// handle the exception
			}
			finally
			{
				// run clean up code IN FINALLY BLOCK
			}
		}
	}
}

C#: 
namespace Tests
{
	using System;

	public class tryApp2
	{
		private static void Main()
		{
			try
			{
				// some code that could throw an exception
			}
			catch
			{
				// handle the exception
			}
			// run clean up code OUT OF TRY BLOCK
		}
	}
}
 
In the first one the Finally block is always run.

The second one will not if there's an error

Both seem to work exactly the same to me

C#: 
namespace Tests
{
	using System;

	public class tryApp
	{
		private static void Main()
		{
			try
			{
				Console.WriteLine("Something is about to go wrong");
				int a = 6;
				int b = 0;
				Console.WriteLine("Division = {0}", a/b);
			}
			catch
			{
				Console.WriteLine("Let me handle this");
			}
			finally
			{
				Console.WriteLine("I always run...");
			}
			Console.WriteLine("And does this run?");
		}
	}
}
 
Thanx, I see now... very important when rethrowing exceptions....

C#: 
namespace Tests
{
	using System;

	public class tryApp
	{
		private static void Main()
		{
			try
			{
				Console.WriteLine("Something is about to go wrong");
				int a = 6;
				int b = 0;
				Console.WriteLine("Division = {0}", a/b);
			}
			catch
			{
				Console.WriteLine("Let me handle this");
				throw;
			}
			finally
			{
				Console.WriteLine("I always run...");
			}
			Console.WriteLine("And does this run?");
		}
	}
}
 
Hi Robby,

I started this thread under the Systax Related subjects for C#, with thread name 'finally'. It seems to be moved to the general pages, but there it got the thread name "DataView RowFilter Hell". I have been reading on the "DataView RowFilter Hell" thread today, but I did not start that thread, and it handled about complete different subjects. Now, I find our discussion under the general subjects with thread name "DataView RowFilter Hell", of which I would be the thread starter.... Any idea whats going on?
 
Maybe you had accidentaly posted in that thread and a Mod split it into this one.

I have since correvted the title.
