使用记录器记录堆栈跟踪
我正在使用 C#.Net 2.0 的日志应用程序块。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，并且工作正常。 但问题是，我不能在 le.Message 属性中放置超过 50 个字符。就我而言，堆栈跟踪长度超过 500 个字符，我想在发生错误时将其登录到平面文件中。
我们可以在 LogEntry 对象的 Message 属性中放入的字符数量有限制吗？或者是否有其他方法将堆栈跟踪记录到记录器平面文件中？
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" />

type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings,
Microsoft.Practices.EnterpriseLibrary.Data, Version=4.1.0.0, Culture=neutral,
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,
Microsoft.Practices.EnterpriseLibrary.Logging, Version=4.1.0.0,
Culture=neutral, PublicKeyToken=null" name="Text Formatter" />
</formatters>
这是监听器，
<add fileName="Logs/ErrorLog_{Date}.log"
listenerDataType="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.
CustomTraceListenerData,
Microsoft.Practices.EnterpriseLibrary.Logging, Version=4.1.0.0, Culture=neutral,

type="EnterpriseLibrary.Logging.Extensions.RollingFlatFileTraceListener,
EnterpriseLibrary.Logging.Extensions, Version=1.0.0.0, Culture=neutral,
PublicKeyToken=null" name="Custom TraceListener" initializeData="" />
类别
<categorySources>
<add switchValue="All" name="ErrorsToEventLog">

<add name="Formatted EventLog TraceListener" />
</listeners>

<add switchValue="All" name="ErrorsToLogFile">

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,

<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,

据我所知，日志消息没有这样的限制。如何设置消息的堆栈跟踪？
To my knowledge, there is no such limit for log message. How do you set the stack trace to the message?
假设您的分析是正确的（我现在不方便仔细检查），您是否考虑过为 LogEntry 创建一个没有您遇到的限制的子类？
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?
