NLOG被寫入文件而不是數據庫表

Question

這是我NLog.config文件：

<?xml version="1.0" encoding="utf-8" ?> 
    <nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd" 
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
      xsi:schemaLocation="http://www.nlog-project.org/schemas/NLog.xsd NLog.xsd" 
      autoReload="true" 
      throwExceptions="false" 
      internalLogLevel="Off" internalLogFile="c:\temp\nlog-internal.log" > 

     <variable name="myvar" value="myvalue"/> 

     <targets> 

     <target name="database" xsi:type="Database" 
       dbUserName="internwebuser" 
       dbProvider="System.Data.SqlClient" 
       connectionStringName="SECURE" 
       connectionString="Data Source=sqlservtest.starledger.com;Initial Catalog=SECURE;User ID=webuser;Password=password" 
       commandText="insert into dbo.tracelog (custom_message, excep_message, insertdate) 
       values 
       (@custom_message, @excep_message, @insertdate);" > 


      <parameter name="@custom_message"  layout="${exception}" /> 
      <parameter name="@excep_message"  layout="${exception:tostring}" /> 
      <parameter name="@insertdate"   layout="${date}" /> 


     </target> 


     <target name="file" xsi:type="File" 
       layout="${longdate} ${uppercase:${level}} ${callsite} from Line: ${callsite-linenumber} ${newline} 
    ${exception} ${newline} 
    ${exception:tostring} ${newline}" 
       fileName="${basedir}/logs/${shortdate}-${level}.log" /> 


     </targets> 

     <rules> 

     <logger name="*" minlevel="Debug" writeTo="file" /> 
     <logger name="*" minlevel="Debug" writeTo="database" /> 

     </rules> 
    </nlog> 

我的控制器看起來是這樣的：

public class ReportController : Controller 
{ 
    private static Logger logger = LogManager.GetCurrentClassLogger(); 

    public ActionResult Index() 
    { 
     try 
     { 
      <!-- some statement --> 
     } 
     catch (Exception e) 
     { 
      logger.Error(e); 
     } 
     return View(); 
    } 
} 

此代碼完全寫入文件但數據庫表仍然是空的。另外，在我的文件中，當我使用StreamWriter來創建文件而不是使用NLog時，應用程序會同時向文件中寫入2/3種錯誤。但NLog只寫入最後一個錯誤。

例如：

在StreamWriter情況下，錯誤是：

Exception Name:ExecuteReader requires an open and available Connection. The connection's current state is closed. 

Exception Name:Object reference not set to an instance of an object. 

但在NLOG的情況下，我只得到：

Exception Name:Object reference not set to an instance of an object. 
and the first one is missed out. 

我StreamWriter方法看起來是這樣的：

DateTime today = DateTime.Now; 

      string path = Directory.GetCurrentDirectory(); 

      string fileName = "error-log-" + today.Date.ToString("MM-dd-yyyy") + ".txt"; 

      var file = Path.Combine(path, fileName); 

      StreamWriter log; 

      if (!File.Exists(file)) 
      { 
       log = new StreamWriter(file); 
      } 

      else 
      { 
       log = File.AppendText(file); 
      } 

      // Write to the file: 

      log.WriteLine("Data Time:" + DateTime.Now);  
      log.WriteLine("Exception Name:" + sExceptionName);  
      log.WriteLine("Event Name:" + sEventName);  
      log.WriteLine("Error Line No.:" + nErrorLineNo);  

      // Close the stream: 

      log.Close(); 

我將該方法傳遞到我的控制器的catch部分。

這裏我的主要問題是寫入數據庫表，儘管我會很感謝使用Nlog而不是最後一個寫入所有錯誤。
