将消息记录到以前创建的日志文件
本文关键字：创建 日志 文件 消息 记录 | 更新日期: 2023-09-27 18:20:18
我正在使用企业库5.0登录我的asp.net网站，
我的web.config文件如下：
<?xml version="1.0"?>

我正在使用以下功能更改日志文件路径：
public static void SetLogFilePath(string filePath)
{
//string logdirectory = AppDomain.CurrentDomain.BaseDirectory + "Logs''";
//if (!Directory.Exists(logdirectory))
// Directory.CreateDirectory(logdirectory);
//logFilePath = logdirectory + (string.IsNullOrWhiteSpace(txtBatchName.Text) ? "" : (txtBatchName.Text + " ")) + DateTime.Now.ToString("yyyy-MM-dd HH-mm-ss") + ".log";
if (!File.Exists(filePath))
File.Create(filePath);
ConfigurationFileMap objConfigPath = new ConfigurationFileMap();
// App config file path.
string appPath = AppDomain.CurrentDomain.SetupInformation.ConfigurationFile;
objConfigPath.MachineConfigFilename = appPath;
Configuration entLibConfig = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~");
LoggingSettings loggingSettings = (LoggingSettings)entLibConfig.GetSection(LoggingSettings.SectionName);
TraceListenerData traceListenerData = loggingSettings.TraceListeners.Get("Flat File Trace Listener");
FlatFileTraceListenerData objFlatFileTraceListenerData = traceListenerData as FlatFileTraceListenerData;
objFlatFileTraceListenerData.FileName = filePath;
entLibConfig.Save();
}
每当我更改日志文件路径并将日志消息发送到文件时，日志都不会转到新创建的文件。日志消息将转到以前设置的文件路径。似乎新的环境并没有立即反映出来。
string path = "C:''Logs''" + DateTime.Now.ToString("yyyy-MM-dd HH-mm-ss") + ".log";
SetLogFilePath(path);
Logger.Write(message, "General", 1, 0, System.Diagnostics.TraceEventType.Information);
如何立即刷新新设置以进行编码？
如何定义"立即"？如果您的意思是在执行请求的过程中，那么我认为您不能通过配置来实现这一点，因为不会为该请求刷新配置。
这是一个基于博客文章Enterprise Library Programmatic Configuration的实现，它似乎对我有用。我不会将配置更改写回磁盘，而是在内存中进行更改。
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
EnterpriseLibraryContainer.Current.GetInstance<LogWriter>()
.Write("test", "General");
string path = "C:''Logs''anotherlogfile.log";
SetLogFilePath(path);
EnterpriseLibraryContainer.Current.GetInstance<LogWriter>()
.Write("Another test", "General");
}
public void SetLogFilePath(string filePath)
{
ConfigurationFileMap objConfigPath = new ConfigurationFileMap();
// App config file path.
string appPath = AppDomain.CurrentDomain.SetupInformation.ConfigurationFile;
objConfigPath.MachineConfigFilename = appPath;

// Release lock(s) on existing file(s)
