logging stack trace with logger

Question

I am using Logging Application block with C#.Net 2.0. My code is logging the error information to a flat file. I have set all required configuration in web.config like listeners, formatters and categories, etc as described in msdn and it is working fine. But the problem is, I cannot put more than 50 characters in le.Message property. In my case, the stack trace is more than 500 charactors long which I want to log into the flat file when error occurs.

Is there any limit on number of charactors we can put inside Message Property of LogEntry object? or is there any other way to log the stack trace into logger flat file?

Here is the simple code.

LogEntry le = new LogEntry();
le.Categories.Add("ErrorsToEventLog");
le.Categories.Add("ErrorsToLogFile");
le.Title = "Error message";
le.TimeStamp = System.DateTime.Now;
le.Severity = System.Diagnostics.TraceEventType.Error;
le.Message = "<text of error's stack trace>";
Logger.write(le);

configuration settings

<configSections>
 <section name="loggingConfiguration"
type="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.LoggingSettings,
Microsoft.Practices.EnterpriseLibrary.Logging, Version=4.1.0.0, Culture=neutral,
PublicKeyToken=null" />

<section name="dataConfiguration"
type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings,
Microsoft.Practices.EnterpriseLibrary.Data, Version=4.1.0.0, Culture=neutral,
PublicKeyToken=null" />
</configSections>

Here is the formatter I used,

<formatters>
<add template="Timestamp: {timestamp} Message: {message}" 
type="Microsoft.Practices.EnterpriseLibrary.Logging.Formatters.TextFormatter, 
Microsoft.Practices.EnterpriseLibrary.Logging, Version=4.1.0.0,
Culture=neutral, PublicKeyToken=null" name="Text Formatter" />
</formatters>

And here is the listener,

<add fileName="Logs/ErrorLog_{Date}.log" 
listenerDataType="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.
CustomTraceListenerData,
Microsoft.Practices.EnterpriseLibrary.Logging, Version=4.1.0.0, Culture=neutral, 
PublicKeyToken=null" traceOutputOptions="None"
type="EnterpriseLibrary.Logging.Extensions.RollingFlatFileTraceListener,
EnterpriseLibrary.Logging.Extensions, Version=1.0.0.0, Culture=neutral,
PublicKeyToken=null" name="Custom TraceListener" initializeData="" />

Categories

<add name="Formatted EventLog TraceListener" />
</listeners>
</add>
<add switchValue="All" name="ErrorsToLogFile">

    <add name="Custom TraceListener" />

Answer 1

To my knowledge, there is no such limit for log message. How do you set the stack trace to the message?

Answer 2

Assuming your analysis is correct (it isn't convenient for me to double-check right now), have you considered creating a subclass for LogEntry that doesn't have the limits that you're running up against?
