使用Enterprise库创建滚动平面日志文件

Question

在我的Web应用程序中,我正在尝试创建用于记录错误和异常的日志文件,但是当我运行应用程序时,日志文件未在我的解决方案文件夹或bin文件夹中创建.

我使用了以下代码.请帮帮我,我遇到了这个问题,提前谢谢你.

使用的命名空间

using Microsoft.Practices.EnterpriseLibrary.Logging;

using Microsoft.Practices.EnterpriseLibrary.Common.Configuration;

.cs文件

        public int GetdeskKMasterRecordsCount(string CircleId, string StoreId)
        {
            try
            {
               throw new Exception("this is normal exception");

            }
            catch (Exception ex)
            {
                BindLog(ex);
                return 0;
            }
        }


        public static void BindLog(Exception ex)
        {
            if (ex == null) return;
            Logger.Write(LogInformation(1, DateTime.Now, ex.Message, " "));

        }

        public static LogEntry LogInformation(int eventId, DateTime timeStamp, string message, string documentName)
        {
            LogEntry logEntryObject = new LogEntry();
            logEntryObject.EventId = eventId;
            logEntryObject.Title = documentName;
            logEntryObject.TimeStamp = timeStamp;
            logEntryObject.MachineName = System.Environment.MachineName;
            logEntryObject.Message = message;
            logEntryObject.Categories.Add("Exception");

            return logEntryObject;
        }

Answer 1

对于企业库version 5.0 and above，微软发布了企业库配置工具，允许您在configuration file. 您还可以从 NuGet 安装此工具，并且可以从 Visual Studio 内部访问该工具Tools >> Library Package Manager >> Manage NuGet Packages for solution并添加适当的EntLib Application Block. 您可以从这里找到指南。

使用该工具我生成了一个配置文件，如下所示：

将其放入 Web.Config 或 App.Config 文件中

  <loggingConfiguration name="loggingConfiguration" tracingEnabled="true"
    defaultCategory="General" logWarningsWhenNoCategoriesMatch="true">
    <listeners>
      <add name="Rolling Flat File Trace Listener" type="Microsoft.Practices.EnterpriseLibrary.Logging.TraceListeners.RollingFlatFileTraceListener, Microsoft.Practices.EnterpriseLibrary.Logging, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
        listenerDataType="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.RollingFlatFileTraceListenerData, Microsoft.Practices.EnterpriseLibrary.Logging, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
        fileName="RollingFlatFile.log"
        footer="---------------------------" formatter="Text Formatter"
        header="---------------------------" rollFileExistsBehavior="Increment"
        rollInterval="Week" rollSizeKB="20000" timeStampPattern="yyyy-MM-dd hh:mm:ss"
        maxArchivedFiles="7" traceOutputOptions="LogicalOperationStack, DateTime, Timestamp, ProcessId, ThreadId, Callstack"
        filter="All" />
    </listeners>
    <formatters>
      <add type="Microsoft.Practices.EnterpriseLibrary.Logging.Formatters.TextFormatter, Microsoft.Practices.EnterpriseLibrary.Logging, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
        template="Timestamp: {timestamp}&#xA;Message: {message}&#xA;Category: {category}&#xA;Priority: {priority}&#xA;EventId: {eventid}&#xA;Severity: {severity}&#xA;Title:{title}&#xA;Machine: {machine}&#xA;Application Domain: {appDomain}&#xA;Process Id: {processId}&#xA;Process Name: {processName}&#xA;Win32 Thread Id: {win32ThreadId}&#xA;Thread Name: {threadName}&#xA;"
        name="Text Formatter" />
    </formatters>
    <categorySources>
      <add switchValue="All" name="General">
        <listeners>
          <add name="Rolling Flat File Trace Listener" />
        </listeners>
      </add>
    </categorySources>
    <specialSources>
      <allEvents switchValue="All" name="All Events">
        <listeners>
          <add name="Rolling Flat File Trace Listener" />
        </listeners>
      </allEvents>
      <notProcessed switchValue="All" name="Unprocessed Category">
        <listeners>
          <add name="Rolling Flat File Trace Listener" />
        </listeners>
      </notProcessed>
      <errors switchValue="All" name="Logging Errors &amp; Warnings">
        <listeners>
          <add name="Rolling Flat File Trace Listener" />
        </listeners>
      </errors>
    </specialSources>
  </loggingConfiguration>

我建议您不要在应用程序的 bin 目录中生成日志文件，而是应该通过将 的值更改fileName="RollingFlatFile.log"为类似的值来指定物理位置fileName="c:\logs\RollingFlatFile.log"

您需要在 LogEntry 上设置一个类别，以匹配配置文件中的类别源（您发布的配置中的“常规”）。如果您打算记录异常，我还建议您查看异常处理应用程序块，而不是编写代码来自己处理创建 LogEntry。
