log4net 在其他机器上不起作用

Question

我创建了一个 Web 服务项目，该项目使用 Log4Net 记录到事件查看器，也可以选择记录到 .log 文件。一切都在我的机器上运行良好，当我尝试在另一台机器上部署它时，它甚至不会登录到文本文件或事件查看器。它甚至没有写入文本文件的事实让我认为它无法找到 log4net.dll 或类似的东西？

当它在我的 global.asax 中点击下面指出的行时，我也会收到一条错误消息：

log4net:ERROR XmlConfigurator: 未能在应用程序的 .config 文件中找到配置部分“log4net”。检查 .config 文件中的 and 元素。配置部分应如下所示：

section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" /

我很困惑，我不知道为什么这不起作用，求助！

运行从以下代码编译的 exe，将源添加到 Windows 中的事件日志中，就像我说的，在我的机器上运行良好：

Option Explicit On
Option Strict On

Imports System
Imports System.Diagnostics
Imports System.Threading

Module Module1

Sub Main()

    If Not EventLog.SourceExists("LendingService") Then
                    EventLog.CreateEventSource("LendingService", "Application")
        Console.WriteLine("Creating Event Source: LendingService")
    Else
        Console.WriteLine("LendingService events already defined to this system.")
    End If

      End Sub

结束模块

您正在 app.config 文件中查找您的配置。要更改此设置，您可以使用：

// Configure log4net using the .log4net file
[assembly: log4net.Config.XmlConfigurator(ConfigFileExtension="log4net",Watch=true)]
// This will cause log4net to look for a configuration file
// called TestApp.exe.log4net in the application base
// directory (i.e. the directory containing TestApp.exe)
// The config file will be watched for changes.

或

log4net.Config.XmlConfigurator(ConfigFileExtension="log4net",Watch=true)]

作为参考：

// Configure log4net using the .config file
[assembly: log4net.Config.XmlConfigurator(Watch=true)]
// This will cause log4net to look for a configuration file
// called TestApp.exe.config in the application base
// directory (i.e. the directory containing TestApp.exe)
// The config file will be watched for changes.
