我写作交流＃窗体应用程序任务是：NLOG：自定义安装程序
- 显示可用的网站的DDL到NLOG安装到（根据我们的内部标准）
- 所需的文件安装到支持NLog
我有工作网站（我没有写）与NLog的功能，我用作基地开始。 Global.asax和App_Code/LogManager.vb之间有一些连接/交互，用于将错误引导到NLog中。我没有写这个部分，所以我认为这可能是问题出在哪里，因为我不知道它们是如何相互作用的...
这意味着我们的实施工程师将其用作部署工具。
（注：这个程序是C＃，但目标网站将永远是VB作为是 我们的生态系统）
文件被复制：
- 斌/ NLog.dll
- bin/NLog.Extended.dll
- Global.asax
- NLog.config
- App_Code文件/ LogManager.vb
在我们的Global.asax中，我们捕捉象这样的错误：
Sub Application_Error(ByVal sender As Object, ByVal e As EventArgs)
' Code that runs when an unhandled error occurs
Dim lastException As Exception = Server.GetLastError()
HandleError(lastException)
End Sub
Public Shared Sub HandleError(ex As Exception)
'Honor the config setting for whether we should do the logging.
Dim hostId As String = ""
If HttpContext.Current IsNot Nothing AndAlso HttpContext.Current.Request IsNot Nothing Then
hostId = " (" + HttpContext.Current.Request.Url.Host + ")"
End If
If ex Is Nothing Then
'OrElse request.Url.Host.ToLower = "localhost" Then
Return
End If
If ShouldLogError(ex) Then
Dim LogManager As New LogManager()
LogManager.Logger.LogError("Global Exception",ex)
End If
End Sub
Protected Shared Function ShouldLogError(ex As Exception) As Boolean
If TypeOf ex Is System.Web.HttpRequestValidationException Then
Return False
End If
If TypeOf ex Is HttpException Then
Dim exHttp As HttpException = DirectCast(ex, HttpException)
Select Case exHttp.GetHttpCode()
Case 404
'File Not Found
Return False
End Select
End If
If TypeOf ex Is System.IO.FileNotFoundException Then
Return False
End If
If TypeOf ex.InnerException Is System.IO.FileNotFoundException Then
Return False
End If
If TypeOf ex Is System.Reflection.TargetInvocationException OrElse TypeOf ex Is System.FormatException OrElse (TypeOf ex Is HttpException AndAlso ex.Message.Contains("Invalid viewstate.")) OrElse TypeOf ex Is System.Security.Cryptography.CryptographicException Then
If HttpContext.Current.Request.Url.AbsolutePath.EndsWith("ScriptResource.axd", StringComparison.OrdinalIgnoreCase) OrElse HttpContext.Current.Request.Url.AbsolutePath.EndsWith("WebResource.axd", StringComparison.OrdinalIgnoreCase) Then
Return False
End If
End If
Return True
End Function
在LogManager.vb：
Public Class LogManager
Private _Logger As ILogger
Public Sub New()
End Sub
Public ReadOnly Property Logger As ILogger
Get
If _Logger Is Nothing Then
_Logger = New LoggerFactory().CreateLoggerNlog("Website")
End If
Return _Logger
End Get
End Property
End Class
和NLOG。 config：

所以，即使最精简的NLog.config它不输出任何东西...尝试了一个简单的日志文件，web服务邮件...什么也没有。我尝试了几个地方旅行错误，但命名var错误，缺少conn.open等，无济于事...
我也尝试绕过检查'ShouldLogError()'，以确保它火，但没有走。
需要其他文件或调整才能让NLog以这种方式工作？
对于{{iis-站点名称}'你确实需要[NLog.Web]（https://www.nuget.org/packages/NLog.Web/），它已经从NLog 4迁移到一个单独的包。请参阅[NLog 4发布文章]（http ：//nlog-project.org/2015/06/09/nlog-4-has-been-released.html）和[布局渲染器概述]（https://github.com/nlog/nlog/wiki/Layout-渲染器）。 NB：NLog.Web是一个官方的NLog包 – Julian
谢谢。这最初是在3x版本中创建的。因此有些混乱。 –
