I want to be able to call a class for logging info to a file with the
filename being tied into the function where the logging is occurring.

When I call the class using something like:

WriteLog.Log(FunctionName,stringToLog);

is there any way of determining the Function name automatically?

Cheers,

I know that in an exception object, you get stack information, that can be
parsed to get the top most/bottom most etc.

Maybe try looking at the "System.Threading.Thread.CurrentThread" object. Or
try looking at reflection, though I doubt anything in reflection will keep
track of what function is currently running.

However, seeing as how it's included in exceptions, it has to be kept
someplace, good luck.

There is a package called Diagnostics (I believe) that gives you the
StackFrame object and others. This should be what you need...

Thanks Jason and Russ.

Unfortunately I'm not sure that I understand.

To explain in more detail.

I have a class that I use for logging events on a website called
WriteLog.

Within the class there is a method called Log that writes the
information to a file on the server.

I am currently passing the method the name of the file to write to, but
want to streamline the code by setting the name of the file to the name
of the function that called it.

For example: I have a method called SqlDb.ExQry() that executes a SQL
query that calls the WriteLog.Log() method twice to write the query
string to the log fine and then write the returned results of the
query.

When the WriteLog.Log() method is called, is there any way that I can
get it to work out the name of the method that called it i.e. ExQry or
SqlDb.ExQry?

Cheers,

Yes, that is exactly what the StackFrame object gets you. There is
another class along with StackFrame (I don't recall the name and don't
have .Net loaded at home yet). The collection gives you the current
execution stack. Inside your Log(), you can "get" the current execution
stack and look "backwars" one StackFrame to get the caller.
