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 mean Microsoft .Net itself does not provide log function? I only need to
log to a local file.

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.

Not really. The closes thing is the Trace and Debug classes. But you need to write some code to make them good logging classes.

Thanks Morten,
I have found one,TextWriterT raceListener. http://msdn2.microsoft.com/en-us/lib...elistener.aspx
After reading through this page, I am still a little confused about how to
use it step by step. Do you have a tutorial?
regards,
George

Does it provide function to keep log size to some threshold? I do not want
the log file too big. Thanks.
Yes, you can limit the size and also let the file appender roll. You can
specify multiple appenders, e.g. for sending your log output to the
console or a trace window.
It's very simple to configure and has a good performance.
HTH,

You can get a "Logging Application Block" in "Enterprise Library"
from Microsoft.
But I would recommend log4net.

Do you have any experiences of TextWriterTrace Listener? http://msdn2.microsoft.com/en-us/lib...elistener.aspx

Does it provide any function of limit the size of log? If it does not
provide the function, are there any way to implement the size limit function
application code?

No, I have never used it. From looking at the doc, I don't see a
limitation for the file size, too
Perhaps it is an option for you to implement a custom trace listener.
All you have to do (sounds simple :-) )is to derive from TraceListener
and implement the desired methods. You have to to the "ringbuffer "
writing yourself.
If you want to stick to MS stuff, how about the enterprise logging
application block?

I have not tried it.
The link you gave say:
Thread Safety
Any public static (Shared in Visual Basic) members of this type
are thread safe. Any instance members are not guaranteed to be
thread safe.
Arne
The bank where I work as a software architect uses Log4Net extensively and
it's very reliable and simple to use.

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

The collection contains a simple class (myCustomClass) which has 1 text

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?
