Note that if you change this to:
Console.WriteLine("'{0}': '{1}'", match.Groups["KEY"].Value,
match.Groups["VALUE"].Value);
you get:
'KEY1': 'value1 '
'KEY2': 'value2 '
'KEY3': ''
'NOTE': 'This is a note '
'NAME': 'Fred Knuckle'
To remove the extraneous spaces at the end of value, change the regex
to this (only changes near the end):
@"\s*%(?<KEY>[^,]+),\s*(?<VALUE>[^%]*?)\s*(?=%|$)"
Now the output is:
'KEY1': 'value1'
'KEY2': 'value2'
'KEY3': ''
'NOTE': 'This is a note'
'NAME': 'Fred Knuckle'
