AssemblyInfo.cs

using System.Reflection;
using System.Runtime.CompilerServices;
using System.Runtime.InteropServices;

// General Information about an assembly is controlled through the following 
// set of attributes. Change these attribute values to modify the information
// associated with an assembly.
[assembly: AssemblyTitle("Catalogi.Web.UI")]
[assembly: AssemblyDescription("")]
[assembly: AssemblyConfiguration("")]
[assembly: AssemblyCompany("")]
[assembly: AssemblyProduct("Catalogi.Web.UI")]
[assembly: AssemblyCopyright("Copyright ©  2017")]
[assembly: AssemblyTrademark("")]
[assembly: AssemblyCulture("")]

// Setting ComVisible to false makes the types in this assembly not visible 
// to COM components.  If you need to access a type in this assembly from 
// COM, set the ComVisible attribute to true on that type.
[assembly: ComVisible(false)]

// The following GUID is for the ID of the typelib if this project is exposed to COM
[assembly: Guid("df78b702-d445-4a44-8d80-2888056184b2")]

// Version information for an assembly consists of the following four values:
//
//      Major Version
//      Minor Version 
//      Build Number
//      Revision
//
// You can specify all the values or you can default the Revision and Build Numbers 
// by using the '*' as shown below:
[assembly: AssemblyVersion("1.0.0.0")]
[assembly: AssemblyFileVersion("1.0.0.0")]

// Log4net
[assembly: log4net.Config.XmlConfigurator(Watch = true)]

我尝试了很多方法来解决这个问题:

  1. 在程序集中添加配置文件的路径,如

    [程序集:log4net.Config.XmlConfigurator(ConfigFile = "Config\log4net.config", Watch = true)]

  2. 将副本设置为 log4net.config 文件的输出

  3. 已将 <add key="log4net.Internal.Debug" value="true"/> 添加到 Web 配置以查看调试

    log4net:log4net 程序集 [log4net,Version=2.0.8.0,Culture=neutral,PublicKeyToken=669e0ddf0bb1aa2a]。从 [C:\Users\MichaelV.PROSEC\AppData\Local\Temp\Temporary ASP.NET Files\root\cd31ee63\e12ae4ed\assembly\dl3cb568d0\dbc1e838_1decd201\log4net.dll] 加载。 (Microsoft Windows NT 6.3.9600.0 上的 .NET 运行时 [4.0.30319.42000])

    log4net: defaultRepositoryType [log4net.Repository.Hierarchy.Hierarchy]

    log4net:为程序集创建存储库 [Catalogi.Core,版本=1.0.0.0,文化=中性,PublicKeyToken=null]

    log4net:程序集 [Catalogi.Core,版本=1.0.0.0,文化=中性,PublicKeyToken=null] 从 [C:\Users\MichaelV.PROSEC\AppData\Local\Temp\Temporary ASP.NET 加载Files\root\cd31ee63\e12ae4ed\assembly\dl3\c63084c384b750_0cf4d201\Catalogi.Core.dll]

    log4net: 程序集 [Catalogi.Core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null] 没有指定 RepositoryAttribute。

    log4net:程序集 [Catalogi.Core,版本=1.0.0.0,文化=中性,PublicKeyToken=null] 使用存储库 [log4net-default-repository] ​​和存储库类型 [log4net.Repository.Hierarchy.Hierarchy]

    log4net:使用类型 [log4net.Repository.Hierarchy.Hierarchy]

  4. 创建存储库 [log4net-default-repository]

在这个问题上苦苦挣扎后,我找到了解决方案。

首先我必须添加一个新的 appsettings 键来定位单独的配置文件:

<add key="log4net.Config" value="config\log4net.config"/>

之后我开始在输出控制台中看到更多信息。我必须首先为我的 Log4Net.Async.ParallelForwardingAppender 添加包 log4net.async,然后我必须将以下内容添加到 Web 配置中,因为它无法加载以前版本的 log4net:

  <dependentAssembly>
    <assemblyIdentity name="log4net" publicKeyToken="669e0ddf0bb1aa2a" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-2.0.8.0" newVersion="2.0.8.0"/>
  </dependentAssembly>

现在一切正常。
