Question

我有一个使用ELAB作为日志记录的Windows服务。在控制台模式下运行服务时，所有日志记录都可以。但是一旦我作为服务启动它就不会发生日志记录。

我检查过的事情：

检查了文件夹权限和
从服务使用的用户
使用PROCMON检查是否尝试创建日志文件
使用绝对路径和相对路径来指定日志文件

我不知道为什么这不起作用。

初始化日志记录：

try
{
    var config = new SystemConfigurationSource(true, 30000);
    var logWriterFactory = new LogWriterFactory(config);
    LogWriter = logWriterFactory.Create();
    Logger.SetLogWriter(LogWriter, false);
}
catch (Exception ex)
{
    var msg = $"{DateTime.Now:yyyy-MM-dd HH:mm:ss} Error loading configuration. {ex}";
    File.WriteAllText(Environment.ExpandEnvironmentVariables("%TEMP%\\mayflower_logging_error.txt"), msg);
    Debug.WriteLine(msg);
}

我的ELAB配置：

没关系。我终于找到了问题。我的控制台模式启动了实际代码，而在服务模式下，我的代码未被调用 - 因此没有记录：）。

EntLib V6在Windows服务中记录
