I have a bunch of exceptions in a file and I want to catch those exceptions by using regular expression. For that the first expression has to match with 'System.' and last expression has to match with the Exception.

How many exception are there in that file I can find out? Please tell me what is the expression for System.NullRefferenceException etc)
or how to write custom exception expression.

I have reffered the Regex website but I did not found anything for my requirement.

Sounds like a terrifying abuse of exception technology which is so good by itself. Why all that?

Is this a log file and you are trying to parse out exception details written to it?

How about:

the ^ says that the match has to start at the beginning of the line
\. to mach the .
. matches any character
* zero or more times
$ end of line

Take a look at:
