EntLib5:Loggin应用程序块未记录到事件日志中(例外:无法构造LogWriter类型)-有人可以帮忙吗? [英] EntLib5: Loggin application block not logging to Event Log (exception: type LogWriter cannot be constructed)- Can anyone help?
问题描述
我只是设置了Enterprise Library 5的日志记录应用程序块部分.我想我已经做对了，但是没有将其记录到事件日志中，它在写入方法上出错，并且给了我以下异常.
I just setup the logging application block part of Enterprise Library 5. I think i have done it correct but its not logging to the event log it errors on the write method and gives me the following exception.
The type LogWriter cannot be constructed.
You must configure the container to supply this value.
任何人都可以给我支票或告诉我我所缺少的..
Can anyone do me a check or tell me what i am missing..
首先，我使用Winforms应用程序在Windows 7中运行.
First of all i am running in windows 7 with a winforms application.
这是我创建日志的方法，您会看到write方法.
Here is my method that creates the log and you see the write method.
public class Logger : ILogger
{
public void SendTest(string test)
{
LogEntry log = new LogEntry();
log.EventId = 300;
log.Message = test;
log.Categories.Add("testing");
log.Severity = TraceEventType.Information;
log.Priority = 5;
Microsoft.Practices.EnterpriseLibrary.Logging.Logger.Write(log);
}
}
我所有的配置都是使用entlib5编辑器构建的，而不是手工构建的.并确认这是entlib.config所在的路径
All my configs were built using the entlib5 editor and not by hand. And confirmed this si the path where entlib.config is
filePath="C:\myapp\entlib.config" />
这是我的app.config，指向我的entlib.config

我仍然遇到错误.

内部异常是

我使用EntLib配置器来创建两个文件.
I used the EntLib configurator to create both files.
entlib.config我接受了默认设置，因为它似乎包含了EventLog侦听器.
The entlib.config i accepted the default as it appears to have the EventLog listener included..

这是我在entlib.config文件中的行，日志为空-ermm对吗?
this is my line in the entlib.config file, log is empty-- ermm is this correct?

我的Logger.write在dll中，但是我的app.config/entlib.config在winforms应用中..winforms应用引用了我在其中写入日志的dll项目.
MY Logger.write is in a dll but my app.config / entlib.config are in a winforms app.. the winforms app has a reference to the dll project where i write the log.
dll和winforms都有对
Both the dll and the winforms has a reference to
Microsoft.Practices.EnterpriseLibrary.Logging
并且也使用统一性，具有
and also using unity, has
Microsoft.Practices.Unity
Microsoft.Practices.Unity.Interception
推荐答案
马丁，您已经创建了基于文件的配置源，但是尚未将日志记录部分重定向到该文件.
Martin, you've created a file-based configuration source, but you haven't redirected the logging section to it.
将以下内容添加到enterpriseLibrary.ConfigurationSource节点内的App.config中:
Add the following to App.config inside enterpriseLibrary.ConfigurationSource node:
<redirectSections>
<add sourceName="File-based Configuration Source" name="loggingConfiguration" />
</redirectSections>
In addition, I recommend the Configuration Sources Labs from the Enterprise Library 5.0 Hands-on Labs set. It covers this and more advanced scenarios.
