c# – 使用记录器记录堆栈跟踪

我正在使用带有C#.Net 2.0的Logging Application块.我的代码将错误信??息记录到平面文件中.我已经在web.config中设置了所有必需的配置,如监听器,格式化程序和类别等,如msdn中所述,它工作正常.
但问题是,我不能在le.Message属性中放置超过50个字符.在我的情况下,堆栈跟踪超过500个字符长,我想在发生错误时登录到平面文件.

我们可以在LogEntry对象的Message Property中放置的charactors数量有限制吗？或者有没有其他方法将堆栈跟踪记录到logger平面文件中？

这是简单的代码.

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);

配置设置

<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,PublicKeyToken=null" />
</configSections>

这是我使用的格式化程序,

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

这是听众,

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