Question

Ruby has an else block that would go in a begin/rescue (try/catch for .NET folks)

begin
 #some code
rescue
 #oh noes! Catches errors like catch blocks in .NET
else
 #only executes when NO errors have occured
ensure
 #always executes - just like the finally in .NET
end

The code in the else block will only execute if no errors have been raised. Is there a construct in .NET that provides this functionality?

Answer 1

In .NET, you can just list the code after #some code:

try
{
   // some code
   // Only executes when NO errors have occurred
}
catch (Exception e)
{
    // Catches errors
}
finally
{
    // Always executes
}

Any exception within // some code will prevent the “Only executes” section from occurring, as it will jump to the catch then finally.
