Log4net不會寫入數據庫

在過去的幾個小時裏，我一直在試圖讓日誌寫入數據庫的表中。Log4net不會寫入數據庫

開啓調試後，我收到以下錯誤語句：SqlCommand.Prepare方法要求所有可變長度參數有一個明確設置非零大小

這裏是我的代碼片段：

和類：

      log4net.Config.XmlConfigurator.Configure(); 
      log4net.Util.SystemInfo.NullText = null; 

      GlobalContext.Properties["UserName"] = userName; 
      GlobalContext.Properties["ProcessModeID"] = processModeId; 
      GlobalContext.Properties["CcCompanyNameID"] = ccCompanyNameId; 
      GlobalContext.Properties["CcExpDate"] = cCExpDate; 
      GlobalContext.Properties["CcID"] = ccId; 
      GlobalContext.Properties["CcOwnerID"] = ccOwnerId; 
      GlobalContext.Properties["CcOwnerName"] = ccOwnerName; 
      GlobalContext.Properties["InvoiceDate"] = invoiceDate; 
      GlobalContext.Properties["CustomerNo"] = customerNo; 
      GlobalContext.Properties["SumWithDue"] = sumWithDue; 
      GlobalContext.Properties["SumWithoutDue"] = sumWithoutDue; 
      GlobalContext.Properties["PaymentTypeID"] = paymentTypeId; 
      GlobalContext.Properties["TaxRegistrationNum"] = taxRegistrationNum; 
      GlobalContext.Properties["TrxUniqueID"] = trxUniqueId; 
      GlobalContext.Properties["SalesPerson"] = salesPerson; 

      log.Debug(string.Format("UserName: {0}, ProcessModeID: {1}, CcCompanyNameID: {2}, CcExpDate: {3}, CcID: {4}, CcOwnerID: {5}, InvoiceDate: {6}, CustomerNo: {7}, SumWithDue: {8}, SumWithoutDue: {9}, PaymentTypeID: {10}," 
            + "TaxRegistrationNum: {11}, TrxUniqueID: {12}, SalesPerson: {13}", userName, processModeId, ccCompanyNameId, cCExpDate, ccId, ccOwnerId, ccOwnerName, invoiceDate, customerNo, sumWithDue, sumWithoutDue, 
            paymentTypeId, taxRegistrationNum, trxUniqueId, salesPerson));

「輸出」窗口中未顯示任何錯誤。

任何幫助，將不勝感激。

嘗試打開內部調試，看看會發生什麼：http://stackoverflow.com/questions/756125/how-to-track-down-log4net-problems –

嘿，對於遲到的回覆抱歉，我已經變成了調試並收到以下錯誤：SqlCommand.Prepare方法要求所有可變長度參數有一個顯式設置非零大小 –

你可以嘗試給所有的字符串參數的大小如下？大小應該與數據庫中的實際大小相匹配。

 <parameter> 
     <parameterName value="@CustomerNo"/> 
     <dbType value="String" /> 
     <size value="50" /> 
     <layout type="log4net.Layout.PatternLayout"> 
      <conversionPattern value="%property{CustomerNo}" /> 
     </layout> 
     </parameter>

好吧，我向前邁進了一步，我需要設置我的小數的精度和比例，你能幫助嗎？與語法請？ –

一般對於固定大小的數據類型（int，decimal，bit等），你不需要指定大小 –

嗯，我確實追加了規模和精度，它確實有效。現在我得到System.FormatException：無法將參數值從字符串轉換爲Int32。 ---> System.FormatException：輸入字符串的格式不正確。 –

我已經解決了這個問題，通過向我的小數添加精度和小數位數並將大小添加到字符串中。另外，我在查詢中錯過了一個冒號。謝謝你們的支持！
