VS 2010 [RESOLVED] WriteAllText: append with a space, multiple variables

Hi all.

I am using the below code to write to a file. Each time this code is used, it appends to the file, with no space between the old and new entry.

1. How can I append with a space between the two entries?

2. What about writing multiple variables? If I have two variables, NewEvent1 & NewEvent2, how can I write both to the file, with a comma between them?

EDIT: Forgot to mention that I want to separate with a comma because I want to read the variables back from the file. So the comma is a delimiter.

Thanks in advance.
