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，请提前谢谢。
使用的名称空间
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;
}

对于企业库version 5.0 and above，Microsoft发布了一个企业库配置tool，允许您在configuration file中直观地更改配置。您也可以从NuGet安装此工具，可以从visual studio Tools >> Library Package Manager >> Manage NuGet Packages for solution 中访问该工具，并添加相应的 EntLib Application Block 。您可以从here找到指南。
使用该工具我已经生成了一个配置文件，如下所示：
将其放在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>

我建议您不要在应用程序的bin目录中生成日志文件，而应通过将 fileName="RollingFlatFile.log" 的值更改为来指定物理位置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”）。如果您计划记录异常，我建议您查看异常处理应用程序块，而不是编写代码来自行处理创建LogEntry。
答案 2 :(得分：-2)
IConfigurationSource configurationSource = ConfigurationSourceFactory.Create();
LogWriterFactory logWriterFactory = new LogWriterFactory(configurationSource);
Logger.SetLogWriter(logWriterFactory.Create(), false);
Logger.Write("btnStartProcess_Click");
Logger.Reset();
