Hello everyone,
I am using C# and Visual Studio 2005 to develop a class library. I am
wondering whether there are any built-in log component in C# so that I can
utilize directly other than write from scratch?
I am also wondering if there does exist such log component, if multiple
processes using the built-in log component to open the same log file to write
log (in my application, I want all processes which loads the class library
DLL to have a common log file), will there be any risk of racing condition
(e.g. interlacing log of one process and another process)? Do we need any
lock/synchronization approach?
thanks in advance,
George

You could try nlog: http://www.nlog-project.org/
Regarding the race condition - I believe most logging components will
worry about this on your behalf.

Hi George,
In addition to Marc's suggestion there is also log4net http://logging.apache.org/log4net/index.html
I haven't tried logging to file, but it seems robust enough that numerous logging sources should not be a problem.

Happy coding!

i typed the last comment all messed up
what i actually do is
1 try to write to my errorsdb..log table
if fails
2. try to write to app defined text file log
if that fails
3 try to write to machine event log
if all 3 of the above fails... well somthing is really broken
i never write to all 3 at once....some people do...
i just think that is a waist of time and resources

You mean Microsoft .Net has no built-in log function?

Does it provide function to keep log size to some threshold? I do not want
the log file too big. Thanks.

I make a similar post in another newsgroup, but this example is
simplified somewhat.
I have a component (cmpMyComponent) with 2 properties. The 1st property
is a string value (Description) and the 2nd property is a strongly typed
collection class (myCollectionProperty).
The collection contains a simple class (myCustomClass) which has 1 text
property (TextProperty).

Hello everyone,
I have created a custom component and one of its properties is a class
object with it's own properties. During runtime, I can assign values to the
class object properties just fine. However, when attempting to assing
default values as designtime in the propertygrid, nothing is working on the
class object. I know that I am doing it wrong, any ideas what it is?
