我收到以下異常，同時試圖登錄使用企業庫5.0的錯誤：企業庫5.0日誌記錄在ASP.Net web服務項目 - 激活錯誤
Activation error occured while trying to get instance of type LogWriter, key \"\""
內部異常消息1：
"Resolution of the dependency failed,
type = \"Microsoft.Practices.EnterpriseLibrary.Logging.LogWriter\",
name = \"(none)\".
內部異常消息2：
The type LogWriter cannot be constructed.
You must configure the container to supply this value."
下面的代碼：
public static void WriteException(Exception ex, string title)
{
try
{
LogEntry logEntry = new LogEntry()
{
Title = title,
Message = ex.Message,
Severity = TraceEventType.Error,
TimeStamp = DateTime.Now
};
Logger.Write(logEntry);
}
catch (Exception exception)
{
}
}
下面是我的web.config：
<?xml version="1.0"?>

的 「門戶」 事件日誌已被創建。
這個相同的代碼和相同的配置在其他項目中工作正常。但是，在嘗試登錄時，我收到ASP .Net Webservice中的激活錯誤。它似乎在嘗試創建LogWriter時無法找到Web.config。
是在你的bin目錄中的日誌記錄DLL？ – NotMe 2012-02-27 20:03:15
是的，日誌記錄以及所有依賴項都位於bin目錄中。 – Auc 2012-02-27 20:30:06
