【问题描述】：

我想用 Enterprise Library 6 在 SQL DB 中记录我的应用程序。

我启动了 SQL 脚本来创建 SQL 事物，我决定将 Logger 放入类库中。

这是我为制作 POC 所做的代码：

便携类内容：

public static void LogToDatabase()
{
    try
    {
        //Bootstrapping logging
        DatabaseFactory.SetDatabaseProviderFactory(new DatabaseProviderFactory());
        IConfigurationSource configurationSource = ConfigurationSourceFactory.Create();
        LogWriterFactory logWriterFactory = new LogWriterFactory(configurationSource);
        Logger.SetLogWriter(logWriterFactory.Create());

        if (Logger.IsLoggingEnabled())
        {

            LogEntry log = GetLogEntry();
            log.Categories.Add("General");  // name of Categorie in EntLib Config editor
            log.Priority = 5;
            log.Severity = System.Diagnostics.TraceEventType.Information;
            log.Message = "Hello dude, from Logger";
            Logger.Write(log);

        }

    }
    catch (Exception ex)
    {
    }
}

private static LogEntry GetLogEntry()
{
    LogEntry log = new LogEntry();
    log.TimeStamp = DateTime.Now;
    log.Title = "TANOLIS";
    log.Priority = 5;                       // default priority
    log.Severity = System.Diagnostics.TraceEventType.Verbose;  // default severity
    log.MachineName = "MachineName";//HttpContext.Current.Server.MachineName;
    log.ProcessId = System.Diagnostics.Process.GetCurrentProcess().Id.ToString();
    return log;
}

这是我在单元测试中完成的配置字符串（我在其中启动 LogToDatabase()）：

    </formatters>

      providerName="System.Data.SqlClient" />
  </connectionStrings>
</configuration>

错误出现在这一行：

LogWriterFactory logWriterFactory = new LogWriterFactory(configurationSource);

并且是

Invalid TraceListenerData type in configuration 'listenerDataType="Microsoft.Practices.EnterpriseLibrary.Logging.Database.Configuration.FormattedDatabaseTraceListenerData, Microsoft.Practices.EnterpriseLibrary.Logging.Database, Version=6.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"'.

感谢帮助我:-)

【解决方案1】：

我终于找到了解决方案，我将using Microsoft.Practices.EnterpriseLibrary.Logging.Database; 包含在调用者（UnitTest）中

问题已解决，但仍然无法正常工作...所以警告，不要使用整个代码 :-)

【讨论】：

可能没有部署 Microsoft.Practices.EnterpriseLibrary.Logging.Database 程序集，因为它是软依赖项（在配置中）。如果这是一个单元测试，您可以使用DeploymentItemAttribute 强制部署程序集。
